I've just got a BSC 12/25 charger and have connected it to a new LiFePO4 330AH battery. It took about 8 hours in bulk to get to 14.2V then went into absorption phase as expected. 20 hours later it's still in absorption, has not gone to float. The app shows an interrupted charge cycle and an active one of a few minutes - keeps resetting the time. Is the charger faulty? Firmware is up to date.
The charger has not been disconnected or powered off since first connected.
