30AH cells, so you only need 10 to make a 36v battery capable of delivering 120A. Looking around Aliecpress, I found 10 for £117, but you can get coupons that would get at least £10 off that. the battery would weigh about 4.5 kg for 1100Wh. At ebike currents of around 20A, they should last for ever. That was quite a nifty charger too. It's around £40. It's very handy for balancing and things like that. There's also a dual channel 6S one for around £50

On the face of it this looks to be a great product for eapc's. As said, with the discharge current we use (say 20A) these things should last well with 10 in series.
I just measured my existing 14Ah rack battery case. It's 140mmW x 350mmL x 60mmH. My tiny brain can't see a physical configuration of cells that would get anywhere near this. The best I can get would be a pattern of 4 with one across the end, double stacked. That gives a case of approximately250 x 250 x 100mm deep. Thatsa bit chunky for a rack:confused:
Perhaps those more conversant with downtube layouts could make this work?
At around 5Kg not sure I would want it hanging out behind the saddle anyway.
Anyone see how it would work practically?
Anyone going to buy 10 and give it a go?
Is that a Russian site?
Is this what they're powering thier drones with?
Maybe there's a market for cells recovered from shot down drones? Too much? Perhaps I should go and tend my cabbages now:oops:

Is there someway of having a hinged "wraparound" battery case that clips onto the down tube ending up with the down tube going through the middle of the battery ?
