I have an eBike battery pack of 78 18650 cells (13s6p) that I need to charge for storage pending a BMS. I have the following specs from the data sheet:
I want to charge the individual cells (of six 18650 each) independently. I only plan to do this once as I plan to have a BMS as soon as possible. I have no way of testing current. I do have a 2A 5v power supply. If I were to put a resister on it to reduce the voltage to 4.5 I assume the current will drop as well. If I did this (tell me if it is a bad idea) how should I alter the charging time to safely charge the cell?
