father was doing some work on the camper and somehow the batteries tripped out on the circuit breakers fitted to the positive terminal.
Once he had reconnected the circuit he found the bms display was flashing constantly "calculating" i checked the setup of the program and everything was as it should have been.
To see what happened next I had him run the fridge overnight with mains power off and this seemed to reset the system allowing a display of 88% capacity in battery capacity.
Does this sound correct I would have thought it be almost instant ?
I also have few concerns about the long time storage of the batteries to quote EV
Prolonged (weeks) charging at 100% SOC is not recommended.
For storage more than 2 weeks
fully charge battery then give it a slight discharge for few minutes
(14v is considered fully charged)
switch off all loads and chargers including solar (circuit breakers or fuses removed)
start process in 3 months time go back to step 1
If greater than 3 months disconnect red positive cable from battery to ensure no parasitic occur
Should this process be done under Storage mode or Touring mode ?
any suggestions appreciated
