BLUETTI B1232 Battery fault

@BLUETTI_CARE I purchased the BLUETTI B1232 LiFePO₄ Battery To replace the deep cycle 12v lead acid batteries in my offgrid camper, it has a Xantrex Feedom XC 2000 inverter/charger in it. Once I received the battery I changed the setting from lead acid to LiFePO charging and charged the battery using shore power which worked fine, I then shut the system down after charging. With the battery connected I turn it on without shore power connected, the battery turned on with a green light then started flashing red and shut down, there was no known draw except the inverter itself.

Looking for possible causes of this as the system was working fine with previous lead acid batteries and the system will start up with the B1232 battery only if shore power is connected when turning it on

Thanks in advance
