Lifepower4 12v 400Ah battery issue

Описание к видео Lifepower4 12v 400Ah battery issue

Having issues with 2 of these batteries. When trying to run the inverter the inverter would shutdown with a low battery voltage error.

I put it on the bench and opened it up to do some tests.

Disconnected from everything the voltage at the main terminals was 13.5+ and the same on the main busbars inside.

Adding any load (even the little 12v spotlight) would cause the voltage to drop to 8(ish) volts at the main terminals, but not at the main busbars.

I didn't tear the other battery apart, but it exhibits the same behaviour.
