Hi guys, So i have a 10S5P on charge with a new BMS fitted. The initial charge from RED to GREEN measured 40.80V. I've left the charger plugged in for at least 12 hours and the voltage is now measuring 41.06volts.
The BMS is one of these: https://www.ebay.co.uk/itm/10S-Li-ion-Lithium-Cell-36V-40A-18650-Battery-Protection-BMS-PCB-Board-Balance/232864260321?hash=item3637caa0e1:g:NBcAAOSwGZxbWie1
If any cell group is greater that 4.2v, i can see from the pcb board that the extra power is dissipated across a 150R surface mount resistor, and the charging of other cells groups stops until the over voltage cell group reaches <4.2v...This is why it is such a slow process right?
Is there a BMS type that someone can recommend that can do the balancing and charge monitoring a bit faster?
