Thanks Azza . I gave it shot cause of the discount. It’s ok for what I want it for. So say 65ah and you can use 80% safely. So really it’s 50ah so it’s good I guess for a battery that’s around 7kg... if it lasts me a few years I will be happy with this battery for less than $400 . Happy birthday for today mate 👍🍻🍺
Absolute pleasure. I have heard good and bad myself and I purchased this because of the discounted price. It will be ok what I want to use it for . Thanks for watching 👍🍻
This is where I bought it from www.ebay.com.au/itm/100Ah-12V-Lithium-Battery-LiFePO4-Deep-Cycle-Rechargeable-Marine-4WD-Replace-AGM/333705030616?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 but I got this for $100 off because it was a 20% off sale ,hence the main reason I purchased. This is 70 amp hour capacity realistically but it has performed very well so far and it does discharge 100ah continuous no problem. There are other cheap batteries on eBay but I’m don’t know what they like. Hope this helped and thanks for watching 👍🍻
Thank you. I did a retest of this battery in another video as this test was claimed incorrect . I retested and got very close results. Thanks for watching 👍🍻
Great video as always mate, do you have any thoughts on the renogy lithium batteries? Also looking to purchase that 3000w renogy inverter you have. keep up the good content
Thanks mate.. I have never had renogy lithium batteries but they are on sale atm and they have 5 year pro rata warranty. I’m considering 2 of the 170ah lithium renogy for when I build my future off grid camper. I love the renogy products. Thanks for watching and appreciate your support 👍🍻
Great video and thanks for a real time capacity test. Side note... You should get a refund but $500 for a 65 amp lithium battery with discharge at 100 amps continuous is not bad for the price.
Thanks Ben hope it was useful for you . I figured that for what I want to use the battery for it will be ok as it was just under $400 and as you say 65 amp hour lithium , you just can’t beat it really . Appreciate the comment and thanks for watching 👍🍻
just wondering , the double anderson meter you used, where did you get it, i bought similar unit from Jaycar , i have a 135ah 12v LFP which has worked fine but am unsure as to its real capacity. i conected my battery just as you did and started the test using a heat gun with variable thermostat , my inverter is 300watt so i set the draw to around 265 watt, it all worked well for about 4 hrs hating checked on the progress at 1.5 hr intervals only to find at 4th hour the meter froze at about 12.5v the heat gun was still wirking but no readimgs. i took the meter back swapped for another rechaeged the battery and repeated the test which gave the same reasult (reading failure after about 4 hrs) , returned it bought another unit with a external shunt, am fitting it into the battery box, as a electricizn i make a great carpenter, waiting furthes reasults
I don't know what stuff costs in Australia vs Canada but our dollar is similar. Here it seems about the cheapest you can get lifepo4 without building it is $10-11/ah
Bought the same battery before watching this(through sunyee). I hooked it up to two fridges that drew upto 9.5amps combined when cycling. I got my 100a/h on two tests.
That’s awesome mate if you’re getting 100ah out of this battery .. im still only getting 72 out of it . For what it cost im not complaining as its holding up well with constant use . Thanks for watching 👍🍻
Hi mate, thanks for the videos really informative, I was going to buy one based on your long term review, looks like I'll give it a miss. I don't know much about lithium batteries but I thought that AH is calculated based on your power draw. Would it be 100AH if you didn't draw as much current in such a short period of time?
I found this battery was only rated to 66 to 67 ah . Though it did put out it’s said maximum continuous current of 100 amps. I have an itechworld 120ah lithium battery and it’s fantastic but it’s around a thousand dollars . You get what you pay for! Also you could go for enerdrive, dcs , allspark or renogy . Hope this helps and thanks for watching 👍🍻
So is it a good battery? I'm interested in a lithium battery for my car. It's $350 so I don't know if I should buy it. That's why I was looking up UA-cam videos on it because it does not have a brand name. Do you think that it's a good deal?
Not really . The kings 100ah lithium battery seems fairly good they are 299 today here www.4wdsupacentre.com.au/100ah-lithium-battery.html or you can keep an eye out on their website and the 120ah are 399 when they are in special . Hope this helps and thanks for watching 👍🍻
The battery will show significantly less capacity as you discharged it as 0.6c (60ah). Typically the ah rating is measured at 0.2c (20ah). You should re-test at 0.2c to see the true capacity, could still be 100ah :)
I did a retest video you can check out and I actually measured the power going back into the battery it was around 72ah... check it out and thanks for watching 👍🍻
How many volts was the battery when fully charged ,I thought I saw 13.7,should have been 14.6, maybe that’s why the capacity was lacking ,maybe try cycling it a couple of times or another charger.
Yep I’m gonna flatten the battery and I’m gonna put the charger on and see what goes back into the battery... battery was fully charged the day before I did this test .
That's still not bad. Currently my battery box has a 75Ah Deep Cycle Sealed Lead Battery and as we all know, you get just over 50% useable out of that. So 75Ah out of one of these gives me almost double the days I can run my car fridge, albeit having to spend more for the battery AND bcdc charger. Aussie Outback have 125Ah on sale for $499 so still not bad if you could get 95Ah useable out of it ..
My battery is going well so far as i been giving it constant use and still going strong. Its only 5 months old . I will do another video on it at the 12 month mark.. thanks for watching 👍🍻
My battery charger would only charge for a short time and then say the battery was full when it was on for about 5 minutes... I found out only just before you commented..lol.. that I connect my charger to the meter and i put the positive clamp to terminal of battery and the negative to the charger side of the meter it works fine as I used the battery to run a little fridge then I only founf\d this out when I charged it.... I will charge the battery this way and see if there any difference.... I’m gonna do a battery capacity test on my itechworld lithium battery in about 6 weeks when the battery is a year old and I will do it with this method....appreciate the comment mate 👍🍻
13.7v is to low for a 4s Lifepo4 battery. (and to high for 3s) (so you battery must be 4s because it will hold 13.7v without melting) 13.7v is fine for day to day use witch is why your charger does that but to get full capacity you need (refer to the data sheet) maybe as much as 4.2v per cell. (though 3.65 is normal) 3.65v x 4 = 14.6v After it's off the charger like you had it in the video it should read over 14v or it's not full To pull full capacity you'd need to fully charge the battery. I would recommend going from 14 to 11.6 if your not happy with the capacity at 13.7v Try not to go to 10.5v (you can and it's not like lead acid so it wont die but it would last longer if you only go to 11.6v (then it might out live you) (though probably not if you keep letting it get that hot) also every 6 months you'd probably want to do a "top balance" so you'd need full voltage (14.6v once no more current is flowing or maybe higher voltage when it's charging)
It's hard for me to pick the best video on this subject but maybe try this. (this one is talking about 1 cell but just remember your battery is 4 cells or "4s") ((4s?p)) ua-cam.com/video/x5ABvbbics8/v-deo.html or maybe have a look at some of this guy's other videos he's a smart kid and there is a lot of videos about batteries on his channel.

Thanks for the review mate. Appreciate you taking time out of your day to do all these for us fans. Wonder if that battery would last under a bonnet? I just installed an agm under the bonnet of my 80 series(a good friend gave me his 100amp battery) but would love to get something like lithium down the track when they reduce in price
Hey Jason. Don’t think it would be for under bonnet use. Is your agm rated for under bonnet use? Just lot of batteries don’t like the heat unless they are rated for under bonnet use. Once you go lithium Jason , you will never go back to agm! Only thing is lithium is a big outlay on the first time you purchase but it’s cheaper in the long run. I actually didn’t regret moving my battery to the rear and mounting air compressor to where I had my battery under the bonnet. But it comes down to how much space you need in the rear with your family 👍🍻
EFFICIENTSELF my mate who had the battery had it under the bonnet of his 105 series. Century battery 100amp agm. I can only assume it is rated for under bonnet as he isn’t the type of guy to cut corners. For now I’ll use it until it stops. Yes I have seen a lot of comments about lithium working out cheaper in the long run. As it’s a freebe for me I might as well use it right? At this stage I have zero room in the back of my car but will definitely keep an eye out for your next review on this battery Dean
Hey I have retested this battery and I checked the specs . It measures to 65ah ...how bizarre, when I said 66 ah , I actually rounded it off to 66AH as it was 65.9?? At this point I had to go to the toilet and when I came back out I seen the meter reset ..lol.. Actually it explains a few things now as I always thought these meters reset after 99ah . Thanks for pointing it out to me or I never would of known......anyway I retested put the meter on the charger and measured the power going back in and 5.815ah was on the meter so say 66AH (as it resets after 65.999) + 5.815. So let’s say 72ah . I got a video coming on it shortly I just gotta edit it when I get some time and upload . Cheers 👍🍻
This test was somewhat unfair to the battery, which held out very well, despite. Test was to fast, over current , not in open air. THANKS FOR THE VIDEO! ...about to look at your other one.....
battery looks a bit small for 100AH i have a similar battery box and my 100ah lithium. I tested mine to 90% Have to watch the heat as they will shut down if they get hot
@@EFFICIENTSELF yes i paid a over $300.00 more than what you gave for that one. So i would expect it may be less than advertised. try doing the test slower so the battery does not get hot and see how much you get out of it over time.
at 2:30 you said that it had been running for almost 2 hours. The current draw shown was constantly between 44 amps and 60 amps odd ... that would be an average around just over 50 amps. It's a 100Ah battery .... ie. 100 amps for 1 hour or 50 amps for two hours ... so it sounds about right to me.
It ran fine on the collapsible jug and 2 drills was approx 100 amp draw on battery . Though I also plug in a small juice blender which was approx 15 amp draw on battery with other items it threw out the bms on the battery . I didn’t video this and I actually forgot to mention this . Thanks for watching 👍🍻
I can’t , sorry , as I just can’t afford to buy batteries to test. I’m not sponsored in any way.All my videos on items I have to buy , as nothing is given to me sorry.. I’m sure there would be a video on UA-cam on these batteries if you did a search. Thanks for watching 👍🍻
@@EFFICIENTSELF hi thanks for you input,, the other lithium battery you have ( not Itech wold) will it run an induction cooktop, thanks for your videos, I take onboard what you say in testing, thanks again please keep up your good work
I don’t think it would on its own maybe if you had 2 of the batteries you possibly could as the battery has an discharge capacity of 100amps so if you had 2 then you have 200 amps discharge . An induction cooktop would require over 100 amps to run through an inverter of course.
Watch a channel call ‘ justin case solar and bush camping australia ‘. This guy uses an induction cooktop in his camper trailer. Check out his videos 👍
You've got to be kidding! You were discharging a single 12V battery at 500+ watts continuous (ie 0.5C) and expecting it to provide rated capacity of 100Ah? A more appropriate test would be constant 20A max draw, or if you wanted to simulate real use, short 50 to 100A bursts followed by long 5A max discharge.
Yes was made aware pf this so i did a retest video after this one . measured the current going back in and it was a similar result . Thanks for watching 👍🍻
You are drawing a lot of constant current which makes the battery run hotter & less efficient Test it again with a much smaller load and you will get more AH out of it
I bought a Mobi 135amp lithium battery on eBay, it works perfectly until it gets down to approx 49amp and then it shuts down every time - not happy with battery or customer service!
I would believe it as I have heard bad things about mobi lithium …. Gotta be careful with these cheaper batteries as you get what you pay for . Thanks for watching 👍🍻
Your test is not valid - way too much current and you put it in an enclosed box where it got hot and may have triggered the high temp cutout. Repeat it at 20 degrees and no more than 20A for a 100Ah battery and see what you get.
@@EFFICIENTSELF Yes and I forgot to thank you for your real life video. I understand your initial disappointment but expect that you might have more capacity than your first measurement indicated. I've bought the 125Ah version (same seller using Ebay Plus) and doing capacity tests at the moment. Looking like I've got best part 100Ah (had 93Ah when I stopped the test to avoid triggering the BMS cutout). Amazing battery for $475 and weighs only 8kgs. Big question is how long will it last as they only back it with a 12 month warranty.
@@philg2468 How'd you go Phil? I was looking at the 135Ah myself but was dubious of performance etc. Sounds like the capacity with still be greater than the 120Ah AGM in there at the moment. not to mention the weight saving. My loads will be much small, so I think one would perform fine, but I'd appreciate your input.
I retested this battery measuring the current going back in and the video is here ua-cam.com/video/9pKuRR3iTps/v-deo.html

also every 6 months you'd probably want to do a "top balance" so you'd need full voltage (14.6v once no more current is flowing or maybe higher voltage when it's charging)
People talking about c rating are thinking more off lead acid batteries. you should be able to pull a high c rate IF YOU CAN KEEP IT COOL.

Hi can you please do a test on a VoltaX and if it will run an induction cooktop please
I can’t , sorry , as I just can’t afford to buy batteries to test. I’m not sponsored in any way.All my videos on items I have to buy , as nothing is given to me sorry.. I’m sure there would be a video on UA-cam on these batteries if you did a search. Thanks for watching 👍🍻
@@EFFICIENTSELF hi thanks for you input,, the other lithium battery you have ( not Itech wold) will it run an induction cooktop, thanks for your videos, I take onboard what you say in testing, thanks again please keep up your good work
I don’t think it would on its own maybe if you had 2 of the batteries you possibly could as the battery has an discharge capacity of 100amps so if you had 2 then you have 200 amps discharge . An induction cooktop would require over 100 amps to run through an inverter of course.
Watch a channel call ‘ justin case solar and bush camping australia ‘. This guy uses an induction cooktop in his camper trailer. Check out his videos 👍

You've got to be kidding! You were discharging a single 12V battery at 500+ watts continuous (ie 0.5C) and expecting it to provide rated capacity of 100Ah? A more appropriate test would be constant 20A max draw, or if you wanted to simulate real use, short 50 to 100A bursts followed by long 5A max discharge.
Yes was made aware pf this so i did a retest video after this one . measured the current going back in and it was a similar result . Thanks for watching 👍🍻
I believe most deep cycle batteries are rated at 20 hrs, in this case 5 amp load over 20 hrs on a full charge.
Reason I brought 135AH I needed 100. all good 👍 a good Expensive 100AH Would have cost me double.
Cheers thanks for watching 👍🍻
You are drawing a lot of constant current which makes the battery run hotter & less efficient
Test it again with a much smaller load and you will get more AH out of it
Yes i did a retest of the current going back in on another video and got 72 ah will retest when the battery is a year old ... its going well so far
I bought a Mobi 135amp lithium battery on eBay, it works perfectly until it gets down to approx 49amp and then it shuts down every time - not happy with battery or customer service!
I would believe it as I have heard bad things about mobi lithium …. Gotta be careful with these cheaper batteries as you get what you pay for . Thanks for watching 👍🍻
The inside cells are not enough capacity
What did you pay for it?
think I can recall a bit over $300 it was from a 22% off sale as they were 399. thanks for watching 👍🍻
Do not use these batteries, my bms set on fire. The inside has expanding foam too
I dont have this battery any longer as it went with my vehicle when i sold it over a year ago Cheers for the info and thank you for watching 👍🍻
Your test is not valid - way too much current and you put it in an enclosed box where it got hot and may have triggered the high temp cutout. Repeat it at 20 degrees and no more than 20A for a 100Ah battery and see what you get.
Will do , I’m going to flatten this battery and measure what goes back in . For the $$$ it’s actually not a bad battery .Thanks for watching 👍🍻
@@EFFICIENTSELF Yes and I forgot to thank you for your real life video. I understand your initial disappointment but expect that you might have more capacity than your first measurement indicated. I've bought the 125Ah version (same seller using Ebay Plus) and doing capacity tests at the moment. Looking like I've got best part 100Ah (had 93Ah when I stopped the test to avoid triggering the BMS cutout). Amazing battery for $475 and weighs only 8kgs. Big question is how long will it last as they only back it with a 12 month warranty.
Yes its the long term to see how long it goes for 👍
Well.done
@@philg2468 How'd you go Phil? I was looking at the 135Ah myself but was dubious of performance etc. Sounds like the capacity with still be greater than the 120Ah AGM in there at the moment. not to mention the weight saving. My loads will be much small, so I think one would perform fine, but I'd appreciate your input.
