I'm new to forum, just learning how to build EV - it is cheaper for me, because I'm living in China.

searching for batteries in, chinese ebay

What I found:

Lithium, 12b 50Ah, 2650rmb, (424$), weight 10kg,0:1340433948_3k1_1783564695

Chinese now using ultra-capacitors batteries, less expensive and more rechargeable, up to 100 000 times

2,5v, 2000F, 60RMB
10000 F, 4 Ohms

Thanks Rick

not long time ago I was living in your area, Riverside-Ontario

Thanks Paul.
Definitive, I will need help
What stopping me now?? Why conversion is soo expensive when on the markets are new electrical cars staring from very low, 3000-5000$? Of course, they may be completely different classes, but still. I also believe, that I can find more economical batteries, still don't know prices for 100 kF, even seen adv for 200 kF.

Chinese are having double pricing - one for international market mostly by traders, other for locals. Alibaba are for intentional market, I already found several product where prices are double what Chinese are paying.

Thanks for calculations, it is very helpful
