I left my van for two weeks; thought I had turned off all loads. Came back and all displays are flat - Kisae DMT1250 doesn’t respond with engine running, Victron 702 screen is blank. No charge accepted with engine on. Hooked a battery charger directly to cable leads to the battery with no result. How do I restart the BMS? Apparently everything drained and hopefully the BMS low voltage protection kicked in. Where to go from here?

Sounds like the BMS went into low-voltage protection. Try waking it up with a small external charge source before using your main charger — here’s a useful guide: NBA 2k20 apk download
