Custom battery for DIY ebike Review by AlexI

In my opinion INR21700-50E cells were the best. I made a pack 13S5P pack for a 21kg bike with front wheel drive 500W motor. I can ride 100-120km at avg speed of 40km/h (assisted). Did 11 charge/discharge cycles till now and didn't noticed any cell degradation. (Posted on 27-08-20)

Excellent quality cells, handles a lot of abuse - physical and electrical. Review by Alexey

Used some 50E cells for my e-bike. Went off-roading with my friend. 200 km in total, no road at all. My friend now needs new battery. His previous was built out of no-name Chineese cells. They didn't survive mechanical stresses. Now he is planning to re-use old tesla battery modules. I'm buying more 50E's. We'll see who wins next summer :)

Perfect for Spektrum DX6e, DX8, DX9 RC transmitter. Review by Johan 53.

It is important to have the cables on top of the cells for these Spektrum transmitters because space is limited. Have two in series and charging is done via a balance connector.
