Need help wiuth my 500e Battery problem after hibernation

[gibson777]

Need some advice! As written on the subject. Been working on a major project -new suspension! and my poor 500e has been sitting since November. Disconnected the 12v to stop any drains, but forgot the magic of BMS! Reconnected everything to take it for a spin, but nada - no contactor clunk and the main battery seems super low (around 48% SOC).

Anyone else revived a 500e battery after a long hybernation? Hoping my BMS isn't fried, but that constant drain sounds suspicious. Maybe I should've left the 12v connected after all?

Did you try running it with FiCOM? It's hard to conclude without scanning it.

Others say messing with the fuse can mess up the car's contactors. You might be able to fix it with AlfaOBD and an OBDLink cable.
