Hey everyone,
Recently bought a China Himassi smart/low temp 12v 100Ah battery. Was working fine until it got cold out (40°F) and now it won’t charge. Brought it inside (house is at 68°F) to help warm it up and out it on a charger. I have a proper LiFEPO4 charger and it says the battery is full. App states SOC is 6%, voltage says 12.7 and both temp sensors say 9°C (48.2°F)… multimeter and victron smart batterysense show 12.2v and 63°F
Are my parameter settings messed up, or is the BMS shot?
Any help would be greatly appreciated, as the company has not been helpful. They keep telling me to charge the battery to bring the temp up to allow it to charge (which I understand), but it seems physically impossible for me to have a battery sit at 48°F for 4 days in a room that’s almost 70, not to mention being on a charger that isn’t pushing amperage because it’s being told that it’s full.
Thanks in advance for your time!
