i just took my trailer out of storage and both 100amp lithium batteries are dead. Tried a trickle charger but that doesn’t work as the battery is not detected (I suspect the internal BMS shut it off as the voltage is too low). I have a jumppack portable booster (https://no.co/gb40) and wondering if it’s safe to use to try revive the batteries? appreciate any help
Jump boost for dead lithium battery?

No.
Very low current input, start very low voltage too like 2.0Vpc overnight then 2.5V then 3.0V and so on.
They may be scrap though, but worth a try.
When batts in storage need to check on them and keep topped up at storage voltage
never Full
and never let drop anywhere near 3.0Vpc, murders lifespan
Really should be able to disconnect the cells from the Battery Murder System

desktop 12v power supply. not expensive. they're all over amazon. can set them to constant voltage mode or constant current mode
