I have a Multiplus 12/1600/70 in our caravan charging a 200AH LiFePo4 battery. It has been working fine but seems to have stopped part way through a charge cycle today and has the Charger and Alarm LEDs on. My BMV says the battery is only 40% but the Multi thinks it's 100%. There is no charge going to the battery and manual suggests those LEDs mean it's a battery connection problem.
I checked the inverter function and it's fine so there's no problem with the battery connection.
Any clues on where to look? Any fuse or breaker in the charging side of the Multiplus? The mega-fuse is OK because the inverter side works.
Any help greatly appreciated.
