I installed 16x Basen 280AH cells for a friend along with a seplos BMS a month ago.
All has been working well and has been through roughly 25 cycles top end 3.4v cut off bottom end 3v cut off
Yesterday I noticed the BMS showing a fault on cell 1, the lead positive to the BMS / Inverter and the pack voltage showing 49.7v
Taking cell 1 out of the group shows its totally dead, zero volts, measures absolutely nothing at all on a DVM or the BMS.
Its not bloated or vented, or overcharged its just gone "open circuit" but putting it back in the pack it passes voltage through from the rest of the cells and registers as 49.7v from cells 1 + to cell 16 -
Anyone experienced this?
Regards
