You probably don’t remember this, but about a year ago I was at your place, Chris and Bec were installing the rear locker on my JK and my buddy Andy was helping you with the coil overs on the Juggy. The juggy didn’t have a battery in it, but we were able to use my jump box to start it… that’s the jump box you should get. I love that thing and it’s saved more people that I can remember. Well… I guess you don’t really need it now. LOL ❤😅
How much of a PITA was it to install? I am considering one of those dual battery kits for my JK. About to add three new amps for the sound system. According to my installer, I should be ok as is, but I have my doubts. Any input is appreciated.
Love your channel. I had to comment here. I have been a technical trainer for several European car manufacturers. On newer vehicles the module that controls the charging rate is programed for different batteries. For example a BMW can be programed for the earlier lead acid batteries (the ones that you have to check the water level) or the later deep cycle batteries. While the batteries perform fine, they can damage the alternator. I don't have experience with changing out a deep cycle battery with a lithium Ion battery, but it could wind up damaging the alternator or the module that controls the charging system. Keep up with the great videos!
I literally within the last 4 days began having issues with my 2020 wrangler starting via remote start and this morning actually had to jump start it. I will be replacing the main battery and will look into deleting the auxiliary battery, as the auxiliary has not worked for the last year. Great timing on the video guys, thank you.
You guys need more dirt bikers in your life. These are the only batteris we use. Im glad your lifestyles have afforded a Ferrari and toys to play. Congratulations on life changing supporters and dedication. Take care and blessings to you two.
2022 Jeep was dead this morning. Used the first post in the fuse box to jump. AAA employee said this was the first time she got a newer Jeep to start. Jeep started right up. She was amazed Thanks
I’ve got 2 hacks for this. 2020 rubicon 2.0L turbo with auxiliary battery start/stop. First, You can put an LED receiver hitch light in there and plug in the 5-pin trailer connection and the Start/stop will be disabled. Secondly, just disconnect the negative battery cable coming from the auxiliary battery, and remove fuse F-42 and works fine. No issues or alerts other that I see ‘start stop disable note after start-up. I have the original H-7 in there and it is still fine and it’s over 7-years old. I’ve got the Odyssey Jeep H-7 but haven’t installed it yet. LI batteries usually don’t take heat or jarring. Just saying. Appreciate your production!
Just 4 weeks ago I replaced the main battery in my JL. When it needs replacing I'll seriously consider the AntiGravity battery if the auto parts store does not honor the standard battery warranty. This is the third battery since 2019, so even at the higher cost for the Antigravity battery it will pay for itself if it truly lasts for 8 years. BTW, I do have a trickle charger on the new battery. Thanks for sharing
This was very helpful. Just had my buddy call me up with his 8 month old brand new JL. The battery was stoned and he tried charging and jumping it to no avail and couldn't start the engine. I used your suggestion and jumped it with my jump box to the auxiliary terminal and it fired right up. Guess the Stop/Start battery must be shot already. Thank You !!!!
Your so tall, says Kevin like he only just noticed, keep these how to videos coming, I'm sure there's a lot of owners who need a head's up, thanks guys 😋
I've been running a lithium starter battery in my V6 Toyota for 3yrs now. Quarter the weight of the factory battery and more than double the CCA, they really are a game changer.
Genesis offroad has a sweet dual matched battery setup. I've been running it for a couple of years now without issues. it isolates main battery from the other battery
I don’t own a jeep but I’m a fan and watch all your videos. I shared this video with my friend (he owns a Jeep) but it was a week too late. This just happened to him and it cost him the tow to the dealership and about $1300 just to get it to the original condition so it will happen to him again. He owns a Sahara and a Gladiator and I believe he is going to trade in the Gladiator for a Bronco. Btw really enjoy Brit on the last video climbing those walls
My new 2023 Jeep JLR has less than 2,000 miles and is sitting in my driveway as dead as a door knob right now. Going to try to jump it tomorrow using this method. Went out and bought a battery jump pack this evening but it needs charged. Not sure if the mini tazer process wasn’t done right after recalibrating for 37” tires or if it’s just a crappy battery. Thank you very much for posting!
You pull fuse F42 and disconnect the aux battery lead from the main battery (the L-shaped one that sits beneath the flat one). Electrical tape the shit out of the aux lead and zip tie it out of the way. Done.
My Antigravity battery exploded after 2 weeks of use. The car was just idling. I had to file a warranty claim and am still waiting for reimbursement. It was 680cca smart version with bms which is much smaller but my truck only requires 640cca and wasn’t on their list. I hope you have better luck!
I’m not sure you showed how to exactly eliminate the aux battery. Does just removing it eliminate the special wiring to it? If it’s not there, do you need to do something special with the wiring?
You have to tie post one and two together. He said he did that but didn’t really mention that again after he said to wrap up the hot wire after you yeet the aux battery. You can also put the positive that was on the aux battery to the positive on the main battery to skip the post one and two jumper.
Those of us who have used Lithium Ion batteries on our motorcycles know to turn the headlights on to warm up the batteries prior to starting to help the cold start issues.
Hello! I have the original main battery, and a 2nd aux battery on my 2019 JLU. Before the 2nd aux battery gave up I had installed a solar panel on the hood. It’s been a year now and knock on wood, my main battery has not died on me. BUT this antigravity battery is a great upgrade! Thanks for sharing this info! More power to your channel! 🤜 🤛
Guys I totally love you all and just so happened my battery kicked the bucket today so I was going to buy one of these batteries sounded awesome and just what I needed because my rig is on the heavy side but I think my idea of a little more expensive and yours is COMPLETELY different. 😅
Just ordered the 94R for my 2021 Power Wagon. 90Amp battery with BMS and remote emergency starter and backup cell? Amazing! Expensive at $1000 BUT it's well worth it for when waaay off grid and the truck won't start.
Hello Guys!!!! Smart video! Here’s a smart tip: buy a Halo Bolt. I’ve helped many motorists with dead batteries. With the Halo Bolt you can charge the battery. In addition, it fills tires with air too! Plus, charges cell phones and has a flash light too! Buy at Amazon or QVC. The Halo Bolt, my smartest buy ever!!!!
JINX! Watched this and two days later my aux battery failed spectacularly, taking the main out with it. We had a real cold spell an I hadn't run the jeep in a few weeks. Went to start her and the electronics went berserk. The wipers came on by themselves, the dash went nuts, every light was flashing, shifter locked - but no start. Had to disconnect the aux just to be able to start it with a boost box. (thanks to your vid!) I'm not convinced that the LiOn battery is the way to go though. Too many stories of them causing fires. Keep your fire extinguisher handy and don't park the stepchild in the garage! I'm going with an AGM - like an Optima. Curious to see how it works out for you. Hope to seen an update sometime.
Ran into the dead aux battery while on a trip in our RV flat towing our Gladiator. Of course the Aux battery is only available at dealers, so we had to plan our route through Flagstaff to visit the dealer. Delete is next! Thanks guys for this video! By the way, Lithium Iron Phosphate, LiPo4, is not like Lithium Ion, A.K.A. Lithium Cobalt used in electric cars. Much more forgiving and no danger of run away heat. LiPo4 are the thing in off shore power in the RV world today. While the up front cost is high, they actually cost much less over their life.
Easier to say "Lithium Ferrous Phosphate" for those, so people don't hear "Iron" and think "Ion" And while they're great, and substantially safer, the replacement for them is already coming, Sodium based batteries, which should drop the cost significantly, as Sodium is a lot easier to source and more plentiful.
Thanks you two we just got our jl Rubicon 2020 love it. But hate the stupid auto start. Just a 4 banger turbo. Absolutely love our jeep way better than the 99 TJ.
thank-you for this great info, just a bit confused with the lug nut being used to tie both of those terminals , when stuck in the middle of nowhere ...purpose/reason...little more on that ...thanks again !!
I have to disagree with your assertion about jump starting. I just bought a 2018 JL and one day it wouldn't start. I tried charging the battery ( which was a few months old) but it wouldn't hold a charge. Id only had it 3 weeks, so i called the dealer requesting a replacement battery, or to get them to locate a drain. They told me that it was the aux battery, which i didnt even know i had and to jump start it return it to them. I jumped it no problem just using the main battery terminals. The dealer told me that the main battery had been replaced but that the aux was the original, so they put a new one on. I have now disconnected it. Great vid and great channel. ( Maybe the UK version wiring is different?)
The only drawback is the charge protection won’t allow the battery to charge in anything below 30 degrees. Keep us updated on how you tackle that challenge this winter. I may be ok in Utah. But Colorado that’s just a no go.
I've had one for 2 years now here in Canada Where it gets -20c regularly in the winter. NEVER has it failed , never has it been weak. IT STARTS IN THE COLD BETTER THAN ANY OTHER BATTERY , AND IT WARMS ITS SELF as current flows thru it and allows the alternator to trickle charge even below 0 till it is warm enough to allow full charging. The heater fan and defrost run at 50% faster speeds than a lead acid battery as they get 13.4 V all the time even as it discharges, even at 20% charge it still has over 13 volts.
I will be keen on the short and long term on this. LI batteries are not meant for extreme temperature conditions. Failure and Fire are both risks under extreme heat and cold circumstances. I can't use this in Montana as the BMS would likely not allow a charge half the year. Heat under the hood brings other risks. Hope you found one that tolerates extremes and if you did, I'll be looking to get one. Have yet to find one that wouldn't bring risk under the hood.
@@2superblus like i said, i'm open, but i have not seen a formal or even informal fit test yet survive super cold and hot under the hood for LI. Open to success stories. Good to hear you have realized success with this. May i ask, is this under the hood or, like the vet in Kev's case, inside your vehicle?
@@offroadsoda it is under the hood of an FJ cruiser. Theses have been tested by folks who were doing trail mapping for the USGS in the Arizona desert in summer as well.
I run LiIon in my dirt bikes. I sometimes start the day in the 20’s. I run the headlight for about 3 minutes and I’m ready to rip. (It starts right up) This is certainly an area to watch, but unless the battery is outside for DAYS under 20 degrees, it should be of little concern. This comment is as of late 2022. I absolutely acknowledge this was and still sorta kinda is an “issue”!
First time viewer. I'm a carpenter and a mechanics son, so the 'that's what SHE said' jokes are great. I almost died laughing when Mrs. LB said it. Someone once called me a pervert, to which I answered: I am not! I have been doing this FAR too long to be an amateur... I am PROvert! God Bless and be well.
Welcome to the LiteBrite Nation! Kevin and Brittany are awesome! As you start binge watching all their videos, you'll catch a lot more of that humor. And just wait until you meet Cricket! Have fun!
Keep in mind that Lithium Batteries, ( lifepo4 too) do not like temps over 120DEG F, under the hood temps may cause issues with wheeling/crawling and heat accumulation. Likewise low temps either. They're rather temperamental temp wise.
I understand it’s a lithium battery and you’re basically buying a jump box as well. But my god that’s a lot of money. Hope it works out well for you guys. I’ll keep watching and I’ll be waiting on that 10 year review
That's a cool battery! Thanks for letting us know about it! Happy Trails to both of you! Bummer, None for Ford PUs and Escapes! Damn! You weren't kidding that they're not cheap! Very costly!
A lot of good information I'm glad my jeeps are 1970 and below my newest addition is a 1970 jeep wagoneer God bless and Happy Thanksgiving ✝️🇺🇸 enjoyed watching ✝️
Brit had the wife laughing, I have never seen wrists bend like that! Great tips on JL's. My F-150 is just like the JL's dies if not driven once a week for 30 + miles. I'm on my second battery in one year with a newer F-150 with all the whistles.
You should get ahold of stradman and see if he has any hook up for some exhaust on the 488. You guys have a pretty bad ass assortment of rides. I love it
Traded in my 2012 JKU Rubicon Call of Duty Jeep yesterday and got a 2022 Rubicon Gladiator. And it's a stick shift!! HAven't driven it enough to play with the auto stop/start, but I don't think that's a wise feature for my manual transmission. I love that new type of battery. But $1200 for a battery is a little pricey. But if it helps and lasts longer, and in your case you've already spent that much on new batteries, so this should take care of all your problems.
I have the auxiliary battery, and have had problems. When I had a problem ,you advised me to delete the auxiliary battery So far, I have had no problems I think that I will follow your advice Maybe I can get Chris to upgrade my jeep
It will be interesting to see how this battery works out for you. I helped a friend hook in a lithium battery with a built in BMS into his jeep by wiring in a dedicated charger for it a few years back, and the heat trashed it in less than a year. The heat you'll probably subject yours to, but I doubt you'll be able to test it out in the cold end of the operating spectrum down there in Southern Utah. As always a great battery
I looked up the battery specs for that exact reason. The manufacturer says operating temp range is 23-140f and not to charge outside of 33-113f. I don’t think that battery will last.
@@rjmcmanamy4337 Yeah I heard one of the reasons why lead acid or gel is better than LiFePh as auto batteries is the temperature limitations. In that you HAVE to make sure the battery is above freezing or else it can't charge. Perhaps they could work in the Ferrari which isn't likely to be outside in the cold too much anyway, and the placement will help it survive the engine heat a bit better. Maybe Kev will have to get Chris to move the batteries into the cab and rewire it to accommodate that very idea. As the Stepchild is probably gonna be parked out in the cold, and working in the heat, quite often.
@@rjmcmanamy4337 cold temperature aversion was the first thing that I thought of. The numbers that you have listed are very consistent with other types of Lithium batteries. Will be very interested in the long term durability, as well.
These are a Lithium Iron Phosphate aka LifePO4. They do have some insulation built into them. I run a dual lithium battery setup in my FJ Cruiser, a lithium starting battery and a lithium deep cycle battery for running my fridge. Living in Wisconsin I am had my lithium starting battery since 2018 with no issues and have been running a deep cycle lithium under the hood for lack of interior space. Both batteries have not had heat or cold issues.
You might be having the plates in the battery breaking internally due to the jarring off-road . Also would it be possible to just move terminal for the aux battery to the other terminal for the main battery if the aux battery dies?
I have always liked lithium batteries and have even had highly Insulated ones. I recommend them for motorcycles because most people don't ride in the freezing cold. But depending on how well they are insulated they drop power big time between 30 and 50 degrees. If temperatures get in the single digits I don't know of any lithium battery that would still start a car unless it had some kind of heating element with it like a tesla. It will be interesting to see how this battery performs this winter.
@ it’s been great so far. Was worried too. I use the XS POWER Titan8 LTO lithium in my Ram 2500 with an IOXUS supercap on the starter side. Much more stable chemistry for use under hood.
@@xTinBenderX nice! Do you use a supercap on the JKU? I've been super worried about running lithium in my jku because it gets so hot under the hood. But I've been hearing some success stories like yours also
@@ElevatedTech2Supercap in the Ram only with a Mechman alternator and larger audio system. I don't blame your concerns. Antigravity has a 5 year warranty on their automotive batteries if that helps.Mine is pretty heavily modded with a 6.0 LS etc.
Strongly stand behind antigravity batteries. I use them in my motorcycles and race cars. But I’m a physcopath and use the smaller ones that look like there meant for lawnmowers to power my cars 😅
Pull the F42 fuse and disconnect the ground wire for AUX battery. That is the ground wire towards the fender, the smaller one on the post. That took care of all my problems.
A JL owner would be crazy not to delete the s/s secondary battery with this big of a risk. I've been a Lithium Ion fanboy for some time. Kevin, l suggest that you look at the spec sheet because of where you line (and play). The one idiosyncrasy of Lithium batteries is that they do not like to be charged in the cold. The BMS on the AG's has a temp sensor, but I can't tell if it has a cold temp cutoff sensor or not. You really need to check that out. What would be fine is for you to start it when charged and the engine warming up will quickly take it abovve 32F, but if it's dead, you may need to devise a plan on how to safely jump start it without hurting the battery. That "never die" feature is pretty cool. I've never seen it before and that may be your way out of the "don''t charge under 32F catch-22" since that feature is inherent in the battery. Anyway, wish I had a JL just so I could delete the second battery ::) .
Lithium Ion batteries like to be warmed up before putting a load on them, turning on the lights, heated seats ect, just get current flowing and they internally warm up.
FYI, I have a JL (2023 High Tide) 3.6 manufactured 1-23 by the vin sticker. There is no longer a aux battery below the fuse box. first clue was the neg batt. cable has changed to a single large wire. (If your 22 has the single wire neg connection it's probably the same). there is still they tray but no longer a battery. Not sure if they changed the system due to issues or not, just thought i would save you some time. I didn't see a TSB addressing this.
The only thing I really need my auxiliary battery for is the remote start feature. Living here in Texas, sometimes it's in the high 90s at 6:00 a.m. in the morning when I get up or it can be 0⁰. So I have chosen to keep my auxiliary battery.
That is indeed a glorious sound coming from the Ferrari! Also, I'm totally amazed at the fact that we now have "smart" automotive batteries! See yall tomorrow LiteBrite!
Could you install a capacitor into the aux battery location? I’ve used them in stereos systems until lithium batteries tech came up. The Ferrari should have a fob with its fob. If the doors are locked how would you restart the battery if there’s no Bluetooth app paired with the battery?
Check out your alternator ,it should be putting out 13.5-14.5 volts @ idle. If it’s lower than that it could kill your new battery like it did the rest. Antigravity batteries work great. Great video!
This is not quite true with modern "smart" alternators like the JL and JT have. Output voltage can go as low as 12.3v or so, depending on the engine loading, battery charge, etc. I had the same battery issue within a couple of months of getting my 21 JT. The small aux battery fails typically and subsequently kills the main battery. This is not related to the alternator (unless of course the alternator is actually bad)
No... at idle you're Jeep should be sitting at 12.7 or so on a fully charged battery, as you drive, you will see the 13.5-14.5 v you are talking about.
I saw video of you helping the guy at Pomona. I have looked all over for a Auxiliary Battery delete. No such luck. Can you and Chris do a video on how to do it? Thank in advance...
Hey Kevin, I'm not sure about the antigravity battery, but alternators get burned up because there is something about the LiFePh batteries, where they can not reach a full charge from an alternator. So your alternator is overheating and burning out. There is a fix though, if you add a lead acid battery to your Jeep, the alternator will stop trying to charge.. You might ask around. Just sayin'.
Great vid guys ….. so I got a quick question how do I charge the AUXILIARY battery without taking it out ? I got a slow drip storage charger ….. what posts do I use and how would I hook it up ….. I do charge the main by connection to Neg/ Positive posts but wondering how would I do that for AUX battery?…. Any help appreciated ….. I love the channel and will definitely be getting the new battery in the vid \_/
Great information. I have a 2020 Jeep Gladiator and if I delete the auxiliary battery, what do you do with the auxiliary battery cables? Do you remove them or reconnect them somehow?
There is a way easier way the what they have shown here. Pull the fuse for the aux batter charger , take the neg off the aux battery which is easy to access from the top and tape the neg up. Boom deleted
I think I will get one of these batteries. But my 2018 jl 2.0 turbos battery has not yet died in 50000 miles. Bit I think I will be proactive. Thanks for video.
Very interesting I have been thinking about dual battery set up for my JKU BUT this is intriguing because of the smart battery technology of antigravity bonus of losing weight. TY
Instead of removing the auxiliary battery or maybe still better to remove and use the Z Automotive Taser mini to permanently turn off the annoying as heck auto/start/stop instead of the nut. Wondering if that would prevent the parasitic drain? These are Lifo and be discharged down 10% to 20% without degradation versus a Lead acid which once it is discharged below 50% it significantly degrades the life of the battery. Some lifo batteries now come with there own internal warmer and perform in colder temp. Wonder if this might be in the works for this brand. And the cost to add a good 45watt solar panel on your roof with solar charge controller for the Lifo antigravity battery to trickle charge it and dividends will be unlimited. For that matter I would recommend at the east adding the a small solar panel and solar charger for a lead acid battery to trickle charge. And again, will pay unlimited dividends. Great tip. Thanks guys.
"Even a Britney can do it" 😆 You guys are awesome! Thanks for this info ..same thing happen to my gladiator but thank God it happen at home where we live in Big Bear and ended up getting a new battery! Gonna look into purchasing one though for peace of mind! Thanks guys! CHEERS!
After seeing this video, I priced a group 35 battery for my vehicle. $835.00 in a non-starter for me. When they become affordable, I will consider them.
My six battery failure caused all kinds of electrical gremlins… service shifter, service 4 wheel drive, service auto start, no brake, no steering etc. new aux and reg battery fixed all problems
I can not find any other information about Jump starting the battery after bypassing the aux battery. If I tape off the ground wire and remove fuse 42, is there still a draw on the main battery? You mention tying the two post together on side of the fuse box. I am just trying to do the best long term option without the aux battery. Thanks much!
All your lithium batts. have their own circuit board built in to monitor voltage per cell and temperature per cell. They are typically half the weight of what we are normally used to.
You probably don’t remember this, but about a year ago I was at your place, Chris and Bec were installing the rear locker on my JK and my buddy Andy was helping you with the coil overs on the Juggy. The juggy didn’t have a battery in it, but we were able to use my jump box to start it… that’s the jump box you should get. I love that thing and it’s saved more people that I can remember.
Well… I guess you don’t really need it now. LOL ❤😅
I solved my aux battery issues by installing the Genesis dual battery system. Absolutely love it!! That is how all Jeeps should come from the factory.

Just ordered the 94R for my 2021 Power Wagon. 90Amp battery with BMS and remote emergency starter and backup cell? Amazing! Expensive at $1000 BUT it's well worth it for when waaay off grid and the truck won't start.
Hello Guys!!!! Smart video! Here’s a smart tip: buy a Halo Bolt. I’ve helped many motorists with dead batteries. With the Halo Bolt you can charge the battery. In addition, it fills tires with air too! Plus, charges cell phones and has a flash light too! Buy at Amazon or QVC. The Halo Bolt, my smartest buy ever!!!!
Yes, this is an important one
I was stranded
When my auxiliary battery drained the main
Luckily, I was stranded right next to an off-road shop
🙏
I love BMS LiPo batteries. I've done the Genesis Gen3 dual system for now, which does a quasi-battery BMS for the lead/acid batteries.
You guys are so awesome love this channel so much! Chris is one bad ass mechanic he needs hear it he is amazing!
JINX! Watched this and two days later my aux battery failed spectacularly, taking the main out with it. We had a real cold spell an I hadn't run the jeep in a few weeks. Went to start her and the electronics went berserk. The wipers came on by themselves, the dash went nuts, every light was flashing, shifter locked - but no start. Had to disconnect the aux just to be able to start it with a boost box. (thanks to your vid!) I'm not convinced that the LiOn battery is the way to go though. Too many stories of them causing fires. Keep your fire extinguisher handy and don't park the stepchild in the garage! I'm going with an AGM - like an Optima. Curious to see how it works out for you. Hope to seen an update sometime.
Ran into the dead aux battery while on a trip in our RV flat towing our Gladiator. Of course the Aux battery is only available at dealers, so we had to plan our route through Flagstaff to visit the dealer. Delete is next! Thanks guys for this video! By the way, Lithium Iron Phosphate, LiPo4, is not like Lithium Ion, A.K.A. Lithium Cobalt used in electric cars. Much more forgiving and no danger of run away heat. LiPo4 are the thing in off shore power in the RV world today. While the up front cost is high, they actually cost much less over their life.
Easier to say "Lithium Ferrous Phosphate" for those, so people don't hear "Iron" and think "Ion"
And while they're great, and substantially safer, the replacement for them is already coming, Sodium based batteries, which should drop the cost significantly, as Sodium is a lot easier to source and more plentiful.
Autozone sells the aux batteries as well.
Im glad yall covered this, just picked up my 2023 JL on friday!
Yall definetly did the most IN DEPTH on this now! This is all solid info!!!
So the caveat to this conversation is which engine you have because you may not have the small aux battery.
@@PynkPwny v6
@@kanenine5838 eTorque? if not then you'll have one if it's an eTorque then you won't
When you eliminate the auxiliary battery does it automatically eliminate the stop,start feature or do you have to disable it also? Thanks.
Thanks you two we just got our jl Rubicon 2020 love it. But hate the stupid auto start. Just a 4 banger turbo. Absolutely love our jeep way better than the 99 TJ.
Antigravity batteries are great, had one on my motorcycle, half the weight and ample power. Never had an issue with it.
thank-you for this great info, just a bit confused with the lug nut being used to tie both of those terminals , when stuck in the middle of nowhere ...purpose/reason...little more on that ...thanks again !!
I have to disagree with your assertion about jump starting. I just bought a 2018 JL and one day it wouldn't start. I tried charging the battery ( which was a few months old) but it wouldn't hold a charge. Id only had it 3 weeks, so i called the dealer requesting a replacement battery, or to get them to locate a drain. They told me that it was the aux battery, which i didnt even know i had and to jump start it return it to them. I jumped it no problem just using the main battery terminals. The dealer told me that the main battery had been replaced but that the aux was the original, so they put a new one on. I have now disconnected it. Great vid and great channel. ( Maybe the UK version wiring is different?)
The only drawback is the charge protection won’t allow the battery to charge in anything below 30 degrees. Keep us updated on how you tackle that challenge this winter. I may be ok in Utah. But Colorado that’s just a no go.
I thought of that as well but the heat from the engine once it’s running would heat it up over 32 degrees no problem
Battery blanket heat wrap?
I've had one for 2 years now here in Canada Where it gets -20c regularly in the winter. NEVER has it failed , never has it been weak. IT STARTS IN THE COLD BETTER THAN ANY OTHER BATTERY , AND IT WARMS ITS SELF as current flows thru it and allows the alternator to trickle charge even below 0 till it is warm enough to allow full charging. The heater fan and defrost run at 50% faster speeds than a lead acid battery as they get 13.4 V all the time even as it discharges, even at 20% charge it still has over 13 volts.
Thanks for the info
I will be keen on the short and long term on this. LI batteries are not meant for extreme temperature conditions. Failure and Fire are both risks under extreme heat and cold circumstances. I can't use this in Montana as the BMS would likely not allow a charge half the year. Heat under the hood brings other risks. Hope you found one that tolerates extremes and if you did, I'll be looking to get one. Have yet to find one that wouldn't bring risk under the hood.
Think again my friend. These Survive Wisconsin winters without issue.
@@2superblus like i said, i'm open, but i have not seen a formal or even informal fit test yet survive super cold and hot under the hood for LI. Open to success stories. Good to hear you have realized success with this. May i ask, is this under the hood or, like the vet in Kev's case, inside your vehicle?
@@offroadsoda it is under the hood of an FJ cruiser. Theses have been tested by folks who were doing trail mapping for the USGS in the Arizona desert in summer as well.
I run LiIon in my dirt bikes. I sometimes start the day in the 20’s. I run the headlight for about 3 minutes and I’m ready to rip. (It starts right up)
This is certainly an area to watch, but unless the battery is outside for DAYS under 20 degrees, it should be of little concern.
This comment is as of late 2022. I absolutely acknowledge this was and still sorta kinda is an “issue”!
@@2superblus what brand of lithium batteries are you running?
First time viewer. I'm a carpenter and a mechanics son, so the 'that's what SHE said' jokes are great. I almost died laughing when Mrs. LB said it. Someone once called me a pervert, to which I answered: I am not! I have been doing this FAR too long to be an amateur... I am PROvert!
God Bless and be well.
Welcome to the LiteBrite Nation! Kevin and Brittany are awesome! As you start binge watching all their videos, you'll catch a lot more of that humor. And just wait until you meet Cricket! Have fun!
Keep in mind that Lithium Batteries, ( lifepo4 too) do not like temps over 120DEG F, under the hood temps may cause issues with wheeling/crawling and heat accumulation. Likewise low temps either. They're rather temperamental temp wise.
I am concerned with battery fires. Lithium batteries have that reputation and like Magnesium fires, Lithium burns hotter when doused with water.
I understand it’s a lithium battery and you’re basically buying a jump box as well. But my god that’s a lot of money. Hope it works out well for you guys. I’ll keep watching and I’ll be waiting on that 10 year review
That's a cool battery! Thanks for letting us know about it! Happy Trails to both of you! Bummer, None for Ford PUs and Escapes! Damn! You weren't kidding that they're not cheap! Very costly!
A lot of good information I'm glad my jeeps are 1970 and below my newest addition is a 1970 jeep wagoneer God bless and Happy Thanksgiving ✝️🇺🇸 enjoyed watching ✝️
Sugar Honey Ice Tee, now you tell me! Oh I just missed this video and paid for a new Aux. And when your stuck, your so stuck. Good video guys!!
Brit had the wife laughing, I have never seen wrists bend like that! Great tips on JL's. My F-150 is just like the JL's dies if not driven once a week for 30 + miles. I'm on my second battery in one year with a newer F-150 with all the whistles.
Was anyone picturing Brit falling over backward and landing on the Ferrari, dropping the battery through the front windshield?
No
Yep!😂
Me
Yes and I was worried for her rounded over back as someone who has thrown my back out way too many times in life lol
You should get ahold of stradman and see if he has any hook up for some exhaust on the 488. You guys have a pretty bad ass assortment of rides. I love it
Can you just move the second lug on top of the first lug to bypass the stop start battery?
Traded in my 2012 JKU Rubicon Call of Duty Jeep yesterday and got a 2022 Rubicon Gladiator. And it's a stick shift!! HAven't driven it enough to play with the auto stop/start, but I don't think that's a wise feature for my manual transmission. I love that new type of battery. But $1200 for a battery is a little pricey. But if it helps and lasts longer, and in your case you've already spent that much on new batteries, so this should take care of all your problems.
I have the auxiliary battery, and have had problems. When I had a problem ,you advised me to delete the auxiliary battery
So far, I have had no problems
I think that I will follow your advice
Maybe I can get Chris to upgrade my jeep
Could have hooked up your battery cables to an auxiliary power jump pack to retain your vehicles settings while swapping out your battery.
It will be interesting to see how this battery works out for you. I helped a friend hook in a lithium battery with a built in BMS into his jeep by wiring in a dedicated charger for it a few years back, and the heat trashed it in less than a year. The heat you'll probably subject yours to, but I doubt you'll be able to test it out in the cold end of the operating spectrum down there in Southern Utah. As always a great battery
I believe where they live it gets cold and they get plenty of snow. Atleast last years videos they had snow.
I looked up the battery specs for that exact reason. The manufacturer says operating temp range is 23-140f and not to charge outside of 33-113f. I don’t think that battery will last.
@@rjmcmanamy4337 Yeah I heard one of the reasons why lead acid or gel is better than LiFePh as auto batteries is the temperature limitations. In that you HAVE to make sure the battery is above freezing or else it can't charge. Perhaps they could work in the Ferrari which isn't likely to be outside in the cold too much anyway, and the placement will help it survive the engine heat a bit better.
Maybe Kev will have to get Chris to move the batteries into the cab and rewire it to accommodate that very idea. As the Stepchild is probably gonna be parked out in the cold, and working in the heat, quite often.
@@rjmcmanamy4337 cold temperature aversion was the first thing that I thought of. The numbers that you have listed are very consistent with other types of Lithium batteries. Will be very interested in the long term durability, as well.
These are a Lithium Iron Phosphate aka LifePO4. They do have some insulation built into them. I run a dual lithium battery setup in my FJ Cruiser, a lithium starting battery and a lithium deep cycle battery for running my fridge. Living in Wisconsin I am had my lithium starting battery since 2018 with no issues and have been running a deep cycle lithium under the hood for lack of interior space. Both batteries have not had heat or cold issues.
Haaaa... Thanks for the hook up! Thanks Lite Brite!
You two are a national treasure - thank you!
You might be having the plates in the battery breaking internally due to the jarring off-road . Also would it be possible to just move terminal for the aux battery to the other terminal for the main battery if the aux battery dies?
I have always liked lithium batteries and have even had highly Insulated ones. I recommend them for motorcycles because most people don't ride in the freezing cold. But depending on how well they are insulated they drop power big time between 30 and 50 degrees. If temperatures get in the single digits I don't know of any lithium battery that would still start a car unless it had some kind of heating element with it like a tesla. It will be interesting to see how this battery performs this winter.
Got the Antigravity battery and the Battery Tracker for my JKU to track possible parasitic drains with an app.
How has your antigravity held up in the JKU? I'm scared to run lithium in the engine bay
@ it’s been great so far. Was worried too. I use the XS POWER Titan8 LTO lithium in my Ram 2500 with an IOXUS supercap on the starter side. Much more stable chemistry for use under hood.
@@xTinBenderX nice! Do you use a supercap on the JKU?
I've been super worried about running lithium in my jku because it gets so hot under the hood.
But I've been hearing some success stories like yours also
@@ElevatedTech2Supercap in the Ram only with a Mechman alternator and larger audio system. I don't blame your concerns. Antigravity has a 5 year warranty on their automotive batteries if that helps.Mine is pretty heavily modded with a 6.0 LS etc.
@@xTinBenderX thank you for all the info
Strongly stand behind antigravity batteries. I use them in my motorcycles and race cars. But I’m a physcopath and use the smaller ones that look like there meant for lawnmowers to power my cars 😅
Pull the F42 fuse and disconnect the ground wire for AUX battery. That is the ground wire towards the fender, the smaller one on the post. That took care of all my problems.
Did doing this throw a code or light a light on the dash??
HUGE THANK YOU!!!!!!
I have been hunting for information on the Aux delete.
A JL owner would be crazy not to delete the s/s secondary battery with this big of a risk. I've been a Lithium Ion fanboy for some time. Kevin, l suggest that you look at the spec sheet because of where you line (and play). The one idiosyncrasy of Lithium batteries is that they do not like to be charged in the cold. The BMS on the AG's has a temp sensor, but I can't tell if it has a cold temp cutoff sensor or not. You really need to check that out. What would be fine is for you to start it when charged and the engine warming up will quickly take it abovve 32F, but if it's dead, you may need to devise a plan on how to safely jump start it without hurting the battery. That "never die" feature is pretty cool. I've never seen it before and that may be your way out of the "don''t charge under 32F catch-22" since that feature is inherent in the battery.
Anyway, wish I had a JL just so I could delete the second battery ::) .
Lithium Ion batteries like to be warmed up before putting a load on them, turning on the lights, heated seats ect, just get current flowing and they internally warm up.
What did you guys do to delete the aux battery? Did you just unplug it and tape off the cables at the aux battery?
FYI, I have a JL (2023 High Tide) 3.6 manufactured 1-23 by the vin sticker. There is no longer a aux battery below the fuse box. first clue was the neg batt. cable has changed to a single large wire. (If your 22 has the single wire neg connection it's probably the same). there is still they tray but no longer a battery. Not sure if they changed the system due to issues or not, just thought i would save you some time. I didn't see a TSB addressing this.
We have issues with the push button start not working in the cold, I've tested the fob, they say the battery is good, now I wonder if it's the aux
Wooo first comment! 😎 Love you guys, love the content and effort put in, thank you very much, be safe and have fun! MLR!
The only thing I really need my auxiliary battery for is the remote start feature. Living here in Texas, sometimes it's in the high 90s at 6:00 a.m. in the morning when I get up or it can be 0⁰. So I have chosen to keep my auxiliary battery.
My start stop stopped working 2 yrs in. Still under warranty. Jeep replaced both batteries. I’ll implement your solution soon.
Thanks for the info!! Our 2018 aux battery is on the fritz. Will be following your advice👍
That is indeed a glorious sound coming from the Ferrari! Also, I'm totally amazed at the fact that we now have "smart" automotive batteries! See yall tomorrow LiteBrite!
Quite the fleet you guys have there!!!
You guys rock! Do you miss Colorado Springs?
On my way to Merus watching this. See ya soon!
Could you install a capacitor into the aux battery location? I’ve used them in stereos systems until lithium batteries tech came up.
The Ferrari should have a fob with its fob. If the doors are locked how would you restart the battery if there’s no Bluetooth app paired with the battery?
The anti gravity Battery was a nice tip
Check out your alternator ,it should be putting out 13.5-14.5 volts @ idle. If it’s lower than that it could kill your new battery like it did the rest. Antigravity batteries work great. Great video!
This is not quite true with modern "smart" alternators like the JL and JT have. Output voltage can go as low as 12.3v or so, depending on the engine loading, battery charge, etc.
I had the same battery issue within a couple of months of getting my 21 JT. The small aux battery fails typically and subsequently kills the main battery. This is not related to the alternator (unless of course the alternator is actually bad)
No... at idle you're Jeep should be sitting at 12.7 or so on a fully charged battery, as you drive, you will see the 13.5-14.5 v you are talking about.
Would you please do a review on these in the future to see how they hold up?
Definitely!
Kevin,
Will 2 batteries like this work in a dual battery set up like the Genesis Offroad Dual Battery Kit (with the aux batt obviously deleted)
Good idea
Yes that would be great to know
Definitely don’t want to give you a wrong answer. I would think so, but to be sure I would send a message to the guys at antigravity!!
Hey kids..., another good vid. Cool battery tech. And I knew Brittany could get battery too! Good for her! Stay safe America...!
I saw video of you helping the guy at Pomona. I have looked all over for a Auxiliary Battery delete. No such luck. Can you and Chris do a video on how to do it?
Thank in advance...
Hey Kevin, I'm not sure about the antigravity battery, but alternators get burned up because there is something about the LiFePh batteries, where they can not reach a full charge from an alternator. So your alternator is overheating and burning out. There is a fix though, if you add a lead acid battery to your Jeep, the alternator will stop trying to charge.. You might ask around. Just sayin'.
Great vid guys ….. so I got a quick question how do I charge the AUXILIARY battery without taking it out ? I got a slow drip storage charger ….. what posts do I use and how would I hook it up ….. I do charge the main by connection to Neg/ Positive posts but wondering how would I do that for AUX battery?…. Any help appreciated ….. I love the channel and will definitely be getting the new battery in the vid \_/
Great information. I have a 2020 Jeep Gladiator and if I delete the auxiliary battery, what do you do with the auxiliary battery cables? Do you remove them or reconnect them somehow?
There is a way easier way the what they have shown here. Pull the fuse for the aux batter charger , take the neg off the aux battery which is easy to access from the top and tape the neg up. Boom deleted
I think I will get one of these batteries. But my 2018 jl 2.0 turbos battery has not yet died in 50000 miles. Bit I think I will be proactive. Thanks for video.
Very interesting I have been thinking about dual battery set up for my JKU BUT this is intriguing because of the smart battery technology of antigravity bonus of losing weight. TY
Instead of removing the auxiliary battery or maybe still better to remove and use the Z Automotive Taser mini to permanently turn off the annoying as heck auto/start/stop instead of the nut. Wondering if that would prevent the parasitic drain?
These are Lifo and be discharged down 10% to 20% without degradation versus a Lead acid which once it is discharged below 50% it significantly degrades the life of the battery. Some lifo batteries now come with there own internal warmer and perform in colder temp. Wonder if this might be in the works for this brand.
And the cost to add a good 45watt solar panel on your roof with solar charge controller for the Lifo antigravity battery to trickle charge it and dividends will be unlimited.
For that matter I would recommend at the east adding the a small solar panel and solar charger for a lead acid battery to trickle charge. And again, will pay unlimited dividends.
Great tip. Thanks guys.
Great video guys!!! Thank you for sharing this, that would suck so bad if you was miles off the beaten path!!❤❤💯🤙
So Wise , Thank You for sharing . To bad I live in Northern Minnesota , I need something that can survive -55
Yo saw your corvette on drift week, can't miss it, tron like 👌👌
😁🤙
Get a genesis off-road dual battery system gives you two full size battery’s which also helps when adding more lighting
"Even a Britney can do it" 😆 You guys are awesome! Thanks for this info ..same thing happen to my gladiator but thank God it happen at home where we live in Big Bear and ended up getting a new battery! Gonna look into purchasing one though for peace of mind! Thanks guys! CHEERS!
Great info! Is there any step by step guide on how to delete aux battery for "dummies"??
After seeing this video, I priced a group 35 battery for my vehicle. $835.00 in a non-starter for me. When they become affordable, I will consider them.
off the subject but for 07 jgc laredo to replace fuel pressure sensor how much it would cost if I take it to the shop to get that done?
Curious to see how well the lithium battery performs in sub zero temperature.
Wisconsin winter rated since 2018.
My six battery failure caused all kinds of electrical gremlins… service shifter, service 4 wheel drive, service auto start, no brake, no steering etc. new aux and reg battery fixed all problems
I can not find any other information about Jump starting the battery after bypassing the aux battery. If I tape off the ground wire and remove fuse 42, is there still a draw on the main battery? You mention tying the two post together on side of the fuse box. I am just trying to do the best long term option without the aux battery. Thanks much!
watched.
saved for watch later,
IF and WHEN ever my JL actually gets built sometime this century
All your lithium batts. have their own circuit board built in to monitor voltage per cell and temperature per cell. They are typically half the weight of what we are normally used to.
How can you tell which battery is causing the issue. Also I was told taking out the aux battery can cause computer issues. Thoughts?
