Recharging 12v/300ah lithium battery

Hello all

please excuse how much of a novice I am only recently started using lithium battery s.


Currently I have a welfare container that runs off of 2 12v/300ah connected as 24v. To this I have a 24v/3000 multiplus inverter plus, 24v tea urn led lights and a webasto diesel heater. I have come in today to find that the batteries were only showing 12v on my bmv.

Tried connecting to mains power but the BMS will not allow my inverter to power on as not to damage the battery. So I have disconnected the batteries as to charge them the one battery is showing 13v the others is showing 0.5v any ideas how only one of the batteries could have dropped this low. Also what is my best option to try and revive this battery if possible.

Also nothing was powered on when cabin was left so unsure what drained the battery
