Good deal Review by Florian

Fast and convenient delivery. (Posted on 08-09-20)
Excellent batteries Review by Daniel
I discharged them from 4.15 - 2.75V with 12.5A, excactly 2.5Ah. I am really surprised they do so well with that price, coming from a Chinese brand.
If their cycle life is good, they are perfect for bigger packs. (Posted on 28-07-20)

I made a E-bike battery pack. good battery around 2,75Ah acording to charger
But it was difficult to weld.

high capacity/low price Review by Andrzej
Bought 20 of them, all tested over 2650 mAh. I use them for rather low current discharge and high current charge rates and so far no complains. (Posted on 17-12-19)
