- Good performance, excellent for the price Review by motorCalc

I ordered 21 cells to set up a 10S2P eBike battery. The cells are really excellent, no need to replace one with the spare cell. Inner resistance of the cell fully charged is 24 mOhm. The battery allows for a range of 45 to 70 km dependant on assist level with an Aikema hub drive. (Posted on 06-04-23)Rating - not great not terrible Review by fero

ordered 105 cells, 2 of them were at 0 volts by the time they came, but rest of them was at 3.5. all of them had nickel dots from previous installations that had to be grinded down but that was expected. The blue plastic housing was scratched at the edges, but none of the cells were dented. (Posted on 06-01-23)Rating - I am disappointed Review by Ome

I bought 100 units in 11/2022. My test: after discharge 2,7v, I charged with Liitokala 500. The battery received 4820 mah, which wouldn't be bad. But after two weeks the voltage dropped from 4.20v to 4.13v. That's bad. (Posted on 13-12-22)Rating - Perfect, like new! Review by Sondy

I have already ordered two times from these cells. Both deliveries perfect! I use the cells in 48V tranction batteries for my vehicles. (Posted on 09-10-22)Rating
