Yesterday tried to access my batteries, which I check regularly while on board, in order to monitor if the cells are balanced, and whether the temperature is appropriate
Had a notification of obligation to upgrade, which I started, and 2 out of the 6 batteries I did upgrade [remains 4 I didn't dare to go on], failed to update when reaching 4%, and had the BMS shut down all systems.
There is no way to find the battery through Bluetooth anymore, as if it's system shut down or is offline,
Tried deleting it from paired list,
Tried using other phone, and still the same.
No way to find these 2 batteries in the victron connect app or through BT.
As I am a floating boat, I cannot stay without power, had to skip the BMS cables of these 2 batteries until I find what shall be done.
Any way to reset the Bluetooth processor of the batteries to default or factory so I could communicate again and restart the firmware update?
Or shall I remove the batteries from the banks and send them for service? (Which is a big mess btw)
Your help is highly appreciated
