Have two brand new 12s5p batteries from Matrix and after only about 10-12 charges the battery will no longer take a charge at all. The time I charged it right before now the charger kept clicking on and off every 3 seconds or so. It did this the entire time it was charging and went from a 3 hour charge time to 8-9 hours.
No idea why the battery did this all of a sudden. It’s not the charger(s), they work as supposed to on the second battery just fine. I am getting the expected 37.5V when I test the leads going into the BMS (charge port/meter wires/XT90 lead).
Anyone having similar issues?
