rated capacity 9800mah(so logically each 18650 cell should be 3250+mAh), real capacity less than 6000mah. I was curious about the content of the pack, so i open it, inside the pack i found 9x18650 2000mAh batteries ORIGINALY LABELED (!!!) as 2000mAh. battery has a BMS tho, so little + to the safety, but it fails to give more than 4A of current safely, on the PCB are 2x 4407 p-mosfet transitors and they are burning as hell if you go over 4amps of current. it should be mentioned how much you can pull from the battery safely. overall, i expected something like this, but man, so obviously ?
all ok
