Thanks

Hi James

Today received my 50 cells.
Fast shipping, just one day before Brexit.. :mrgreen:
Cells looks very good and well packed.
I´m very happy with my purchase.

Used the cells I bought from James today and they performed very good indeed.
The voltage drop I experienced(ebike) with other chemistry cells was much less noticeable with these.

I like these, I like them a lot but according to my
calculation I need approximately 100 of them for my scooter, and when I look at energy density (either by volume or by mass) these seem not that great compared to let's say 18650 - is this the case or am I missing something?

Hi they are around 180wh kg ...what makes them great is they are super easy to connect..M3 screws
Can discharge at 5c continuous and 10c bursts...
Also these are OEM cells .. very well matched..
I have some bussbars cut
And £9 a 20ah no solder cell .

What voltage is your scooter? If it's a 72V system you need 20 in series. If your calculations result in 100 pieces that means 5 of those 20 series in parallel for a 72V 100Ah battery pack. That is a huge pack! What power does your scooter have and what is your desired range?

What kind of BMS and chargers are you guys using with these cells?

Interested in getting 20 of these for a 72V 20s 1p battery setup - shipped to Ireland

Slim version of 300A
Ant BMS now. It have super nice app on iOS and not that nice on Android, but it works 😀

Got the cells from jimbob, took no time to get to Poland. Definitely recommend!

Working on building the pack now, waiting for the BMS from China...

72V 20s 1p battery setup
for me, no bms; i just monitor pack voltage and ah/wh used via the cycle analyst, and be sure to charge up before longer trips (or plug in at destination while there). the cells i have are old and were used before i got them, and even now (at least several years after i got them) they're still working about the same, with a little lower capacity, but still staying balanced on their own, since they are good quality and pretty well matched (good qc at the factory to keep all the cells they ship out within a narrow range of specifications), and they seem to stay matched as they age.


i have used the cycle satiator, but at present am using a meanwell hlg-600h-54a to charge my 14s2p pack at a little more than 0.25c (about 12a) to a bit more than 57v.

for a 72v pack, you could use two meanwells in series; not sure if the 54a will turn down low enough (about 83v, or 41.5v each, for your pack) to use two of them in series for it, or if you would need one to be a lower voltage model, or use two identical lower voltage models.

if you use lower voltage models they will be capable of higher current, as the systems are watt-limited by the heat they can shed (fanless, potted and sealed, so good for mounting right on the bike or vehicle. the one on my sb cruiser trike is mounted under the deck, and has been submerged in flash flood waters at least twice with no issues over the years).

but since 0.5c on a 20ah pack is about 10a, you wouldn't want to charge them at a higher current anyway, so the 54a would work for you if two in series can be adjusted down to the 83v or so.

Yes I am following suit with my intended large capacity motor (barge propulsion) battery
I will manually manage the pack and set charging at 4.05v per cell in my 48v set up with a low voltage disconnect of around 3.5v
So the pack is never heavily discharged..
So far I've tested many boxes of these cells and they have all been at pretty much the same voltage out of the box..
Load tests have shown near identical capacity also.
I will be the BMS for now and see how things go...😊🙄🌝
