DJI Smart Controller RM500 battery - can't unseal

[vvzinovyev]

Hi all,

Searched a lot, but can't quite find any information on unsealing the RM500 battery. Mine was shelved for couple of years, but the cells are still reading 7V. I'm able to connect with raspberry pi and dji-firmware-tools and read the battery information. But none of the unseal keys (default and some others) that I found worked. The battery shows that PF is active and one other flag - 'trip point interrupt' reads '1' as well.

I'd appreciate any assistance.
