Good, "honest" elements (Posted on 09-01-21)Rating - Samsung INR21700-50E 5000mAh - 10A Review by Ben R. Eindhoven

It's getting a bit old but everything was as usual: Great battery. great service, acceptable pricing and fast delivery. You're welcome. (Posted on 16-10-20)Rating - 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)Rating - Excellent Review by Patrik

The ones i've tested at 0.5A have been 5000-5200mah but will do more tests at thebatterydoctor.eu (Posted on 06-01-20)Rating - 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 :)Rating

For guitar amplifier 150w (Posted on 30-07-19)Rating - 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.Rating
