In perspective, a 12v 8.4Ah SLA battery would be 100Wh at 100% discharge and would weigh ~5.5lbs. To make the comparison the most realistic you would typically see 500 charge/discharge cycles at a 60% DoD so an equivalent battery size for 100Wh would be closer to 12v 14ah at 60% DoD and would weigh about 9 pounds. So lead acid would be around 1/3 the energy density of the lipo power cells and about 1/10 the energy density of the lipo cells optimized for energy density.
Thanks, Jehu. You rock. I love the info. I hope to build my own power wall in the next year or two, and maybe electrify my 1970 VW, but it's a heavy camper. Maybe better to convert a bug or.... A GREMLIN!
It was nice to see them grouped by energy density. If you can arrange the same batteries in groups of matching power so we can see the power density that would be nice. I think the Panasonic batteries were chosen by Tesla because they are the best compromise between power and energy density. I think we will start to see more EVs using high energy, low power cells, but more of them, to get cheaper range in a car that doesn’t have to be very quick (like Chevy Bolt). But if we want a quick car, we can use high power, low energy cells like Chevy Volt uses. If you replaced the cells in a Chevy Bolt with those from Chevy Volt, you might only have 40 kWh but it would have enough power to drive the motors in a P100D, but much lighter. But if the Tesla Roadster shows you can get performance just by adding more cells which are a compromise between power and energy, then that seems like a good way to go. But it makes you wonder what it would do with 100kwh high power battery instead, and is 1000 pounds lighter.
Pouch cells!! More efficient packaging than cylindrical cells. A123 makes very high power cells like that. Pouch cells are used to manufacture prismatic cells (best way to go in my opinion).
Thanks for the visuals. This confirms that an electric toothbrush Lithium Ion is likely under 100Wh is size and can be carriend in your check in baggage on an airline. lol.
I disagree Jehu, I think the electronics is useful. Pair that board with a bigger 3S battery to power an old laptop for say monitoring a powerwall, weather station etc. 18V is a good voltage to run 6 series leds, if you can limit the current. Output Voltages: 16V 17V 18V 19V 20V 24V No idea what failed in your unit, seems likely it was the battery related, as there are multiple temperature sensors and thermal fuses attached to the cells, and it did work for a little while.
Just curious, I've been watching your videos for awhile now, but I haven't still figured this out. What battery type is best to build a portable power bank for something like car camping / rv'ing? I see most people go the LiFePo4 route. But, it seems you like Li Ion batteries instead for building portable power banks. Personally, I don't mind the lower energy density and weight of LiFePo4, since they have great longevity and are much safer than standard Li Ion or Li Poly. But, besides that, why would you go Li Ion instead? Cheaper?
Can I recommend an ESD bracelet and cable to ground yourself? Of course only when working on lower voltage systems. I just worry about you bricking a lot of your projects with static. Love your videos though. I love your dedication to this stuff and I hope I get to play around, experiment, and learn this much about batteries someday!
You seem very knowledgeable. I'm building an electric motorcycle. I'm debating between 18650 cells battery pack @ 72 volts or 66260 cells. I'm new to this, I'm trying to consider fast charging and range. Unfortunately there isn't much on UA-cam about 66270 cells. What do you think?
Planning to make a li-ion backup battery for a sump pump. Can you explain in a video how to calculate the load and build a backup for different application?
Hey thanks for doing what you do, Jehu. I'm on the verge of investing in some of the paper wrapped fullriver cells to build a marine battery pack for my boat, so i'm very interested to see what you find out about them.
Great comparison! But how can we find those green batteries for an reasonable price? A bunch of sellers are asking a way too much for each cells.3 to 4 dollars each. 100 cellas could cost us $300 to $400 plus shipping. Can you give us a link?
great video as always! if I'm not mistaken buying Tesla Modules from a 85kWh battery are cheaper than your Panasonic cells even at ~$900 per module... and that includes the cooling, mounting hardware, BMS, etc
we've purchased several p85 packs in Europe for under 11,000 euros (~13,500 USD) all with less than 5,000 miles... so yes they're used but at 1.90 USD per cell it shows how aggressively priced Tesla parts are. I love Jehu's work and think it's useful to compare apples with apples :-)
Good day, in your opinion which of the following cells give a better result for 5 amps of constant discharge and peaks of 10 amps? PAMASONIC NCR18650GA, SAMSUNG INR18650-35E OR LG 18650 INR18650MJ1. Thank you
Man oh Man!!! Where do you get 3400mah for 2$ a cell(sign me up!!!). I have searched all over the net and can only get them at $4.50(only because I deal with the seller often). Those 2600mah is pretty much the same way. Unfortunately, the average user or DIYer can only purchase lower amounts. It seems like you can only get deals if you purchase in higher quantities. For me to purchase anything like 100 or more at a time, could be a waste of space and degradation on the cell based on how long they might sit before I use on a project. When purchasing cells, the average DIYer, will only purchase what is needed, unless they have endless supplies of cash. Unfortunately, I am a poor boy and save my money for each project. I have to purchase by project or break the bank. 3400mah for 8 cell would cost an average user 40$ not including shipping and that is a killer deal, they are typically 64$ and above for 8. Those Samsung 2600 you have would run me a little cheaper. normally around 3$ a cell at the average cost. so for 10 would be around 30. I have seen these a little cheaper at times. around 2-2.50$ a cell. Alarm hook up wants 50$, shipping included. for the laptop charger(pouch cells) Edit::::I'd like to also point out...The charger that comes with these are 15V 6amps(90watts). That alone is probably worth around 10-15$. That is a pretty good charge. The LIFEPO4 he is selling, 4 for 40$, but they are a little big--Maybe the cheapest and best deal??? But it may also require additional hardware to use with the project. The Fullriver LiFePO4 you can only get a box of 60 for 120$ plus 32$ shipping.(haven't really looked for smaller deals)-Don't know to much about these? Looking at all those deals, and the pricing. For the average DIYer, the 3400 if you can find them under 5$ a cell is the best deal, but not normally what you can find them at. The 2600 could be the next best, based on cost, but they are only 2600mah. I wouldn't even consider the Fullriver or LifePo4 unless I had some extra cash to burn. 49$ for the pouch cells is starting to sound like a pretty good deal as long as they still retain the 3400mah per cell(guessing based on count). The Tabs also look like those might be strong enough to carry a good amount of amps. Probably nothing like the 3400NCR, but pretty close. But then again, I try and steer away from Pouch cell. To Scarry!!! Great Video Jehu...Just wanted to add my 2 cents... Edit: Just realized, I can only find the 2600 in smaller qty for around 5$ a cell. so for 10 it would cost me 50$. All the battery prices you mentioned would be nice if you can find these in smaller qty the average user could afford. But you can only get them at lower prices if you buy in HUGE qtys. 2$ for NCR18650B is impossible, you can't even find the NCR18650F at that price. NCR are very expensive. The Samsungs at 1.75$ a cell is also impossible unless you purchase in huge qtys.
Me to, I thought for sure I saw those sold at a cheaper rate. Looking online, I can only seem to find them at 5$ and up. Way to expensive for my taste. I can't see paying that much for 2600, when you can find higher rated 18650's for around the same price.
I'm also quite interested in the cheap source for these cells, best I can find on AliExpress is $4.45 each at 100 cells. Ok looks like maybe he was using the price of Tesla cells out of a Smart module, $2.09/cell at 330 per $690 module. Edit: nevermind those are lower capacity, only 2500mAH per Jehu's earlier testing and also impossible to break apart. The real Tesla model S modules are more expensive at $3.15/cell for 444 qty in a $1400 module.
What the heck... How is AlarmHookUp getting NCR18650Bs in such huge quantities? They must be right close to Panasonic's factory. Also, scotty, you can get the LG equivalent of the NCR18650B new here on Li-Ion wholesale. If you buy 100 of them, you'll be getting 3.92$ per cell, which is a good price.
you mentioned that you werent going to talk about your power wall that uses the 36v packs because they are sold out everywhere. but there are plenty of us who have purchased those 36v packs with hopes that you would talk about it SO PLEASE MAKE IT :P
actually, the right way to take that apart... just use a heat gun on the bottom to release the glue and then pry it with plastic..not metal pliers. n should come out without curring anything
Unless you're getting them cheaper than ANYWHERE else. I believe your math is wrong about the Panasonic. I found them at $3.50 or so from a wholesaler + shipping. So that's well over $4/cell or twice the estimated price you suggest
Do you ever cosinder to buy or make a 3d printer?? I think you will need it for some battery pack projects or anything... If you want to build your own.. Check reprap for info... It's a library wiki for open source tech around 3d printer...
Would it be usefull to make a car with mixed battery technologies? Smaller portion for the boost and bigger for range..or is it totally pointless because of motor limitations or something like that?
What about a portion of a battery that can be changed on the go. You know.. you have one chagrin at home, the other one at your destination and you just switch it when you come there if you don't have time refilling it. In the meantime the fixed one is just acting like a reserve.
Es posible que hagas videos en español ? estoy inscrito a tu pagina deshace tiempo y la veo muy interesante y me decepciona no poder entender lo que dices.
Yeah those lifepo4 I was saving for those but till you guys arived the guy increased the price so now is way out of my budget and I juat had gotten to the price I was so happy going to buy then when boom I saw the difference in price then I asked him and he liked me here
Yep. Jehu's battery videos are a blessing for sellers and a curse for buyers. The publicity they generate create a demand spike and the sellers crank up their price accordingly.
jehugarcia I don't mind is going to good weel I quess so no problem there but I have acees to bounch of used laptop abtteries from school but I cant power inverters of lithium ion only lifepo4 I'm 17 so its hard for me to make money cant find a job
I'm confused by your pricing, you say the ncr18650's are available for $16 for 100WH ... (so $160/kw) yet the cheapest ncr18650 battery listed on your where to get batteries page for the tesla batteries is $230/kwh (the smart one) ... Also, any tips for international used-battery-hunters (local on ebay even used cells are selling 3-4x your prices)?
Hey man ...great videos...love them...but the links in your comments doesn't open on my phone...haven't tried opening on PC yet ...but I'll check out...
Yes, check out Mazda I e loop www.mazda.com/en/innovation/technology/env/i-eloop/ Or check out the adaptec raid card battery storage.microsemi.com/nr/pdfs/6514_series5z_1_7.pdf But as Jehu said not a good battery due to high cost and low energy density. However, they have extremely high power density, and are good for thousands of cycles. Therefore, they are good for capturing the energy in braking for a car. Or for protecting data loss on hard drives for computers that get shut off every day. Edit: Not to mention fire hazard and heat tolerance. Lithium is extremely volatile and could blow at any moment. You don't want small explosions in a data center. Super caps also tolerate the heating and cooling cycles of being in the engine bay of a car better.
Tom releases cells for sale every week. most sellout fast, last week he posted these j35.us/NCR18650B-2dollar j35.us/NCR18650BF-2dollar these 2600mah are still available j35.us/2pQ9AvM
Horrible design !! this 75w power bank has so much wasted useful space !! so bad that this guy do not like Jeep Wrangler and did not make it electric version ((
In perspective, a 12v 8.4Ah SLA battery would be 100Wh at 100% discharge and would weigh ~5.5lbs.

So lead acid would be around 1/3 the energy density of the lipo power cells and about 1/10 the energy density of the lipo cells optimized for energy density.
Can you do a video on graphene batteries?
Thanks for your analysis, Jehu. Always enlightening.
Love your videos, keep it up and the momentum will keep growing!

i like how your dog is just chilling on the sofa
Planning to make a li-ion backup battery for a sump pump. Can you explain in a video how to calculate the load and build a backup for different application?
$16 for 8 NCR18650B cells totalling about 100Wh? So $2/cell? New? Where?
Probably Alibaba if you buy like 1000 of them
more laptops need to use 100 watt hour batteries because that is the maximum legal limit to travel with and you could maximize use time.
I like the T-shirt print

I love Jehu's work and think it's useful to compare apples with apples :-)
yeah buying $10K worth of batteries can get the price down, buy you only need to buy 100 cells from TOM to get these prices j35.us/LAST-SALE-2017
sure :-)
Always great info from you ...thanks! And how do we get a notification of when you find a battery deal?
That's a AIMO voltage meter, model MS2108A, AC and DC clamp amp meter right? I got one also from AliExpress for 29,50 dollars. It's been great to me.
Good stuff, thank you! What charger do you recommend for diagnosing round cells?
I am looking at buying a SkyRC MC3000 right now.
I wonder how many li-ion cells needed to make 100wh pack, and how to count the value?
Maybe you should start an Aliexpress "cheap solar/charging/battery stuff" series. Cause I imagine there are some cool projects to find over there too.
Thank you Jehu!!
Good day, in your opinion which of the following cells give a better result for 5 amps of constant discharge and peaks of 10 amps? PAMASONIC NCR18650GA, SAMSUNG INR18650-35E OR LG 18650 INR18650MJ1. Thank you
I think you should have yourself checked in for a possible battery addiction ;-)

Hi sir, how can you determine the type of battery if there aren't any labels on the casing or the pack itself?
Please look into Salt Water batteries. They can be completely discharged for 3500 charge cycles and have 90% DOD from my understanding.

Yeah those lifepo4 I was saving for those but till you guys arived the guy increased the price so now is way out of my budget and I juat had gotten to the price I was so happy going to buy then when boom I saw the difference in price then I asked him and he liked me here
Yep. Jehu's battery videos are a blessing for sellers and a curse for buyers. The publicity they generate create a demand spike and the sellers crank up their price accordingly.
I have read several people offered a much lower price and the seller excepted.
Curse for a small number of buyers, most people don’t know where or how to look for best prices and they benefit from my videos

hi mr garcia what u think abour super capacitor ? i think better than lithium batterys.
can u say somethink please
super caps suck as batteries
Is not it possible to use it like a battery?
Yes, check out Mazda I e loop www.mazda.com/en/innovation/technology/env/i-eloop/
Or check out the adaptec raid card battery storage.microsemi.com/nr/pdfs/6514_series5z_1_7.pdf
But as Jehu said not a good battery due to high cost and low energy density. However, they have extremely high power density, and are good for thousands of cycles. Therefore, they are good for capturing the energy in braking for a car. Or for protecting data loss on hard drives for computers that get shut off every day.
Edit: Not to mention fire hazard and heat tolerance. Lithium is extremely volatile and could blow at any moment. You don't want small explosions in a data center. Super caps also tolerate the heating and cooling cycles of being in the engine bay of a car better.
Saw a video that showed a guy that used a capacitor to replace the battery for starting his cars.
it was a hybrid super cap coupled with a lithium iron phosphate battery. together, they start the car. was lasersabre channel.
where can i get them for 2$ a batt?!?
