Based on various documentation and community threads we have decided to do the following for winterizing our boats:
- deplete batteries to around 60%
- disconnect the Multi/Quattors connected
- disconnect all the loads, even BMS and BMV
Since we usually have 12V chargers with AGMs connected on the AC out, would keeping the Multi/Quattro On without batteries connected work to tickle charge the AGMs over the winter? I suppose when this doesn't see the BMS it would immediately disable charging, but would the passthrough work? Do you think we will need to reconfigure the chargers to remove the assistant and set the max charge to 0 Amps?
We would like to avoid rewiring to whole thing and connect AC out to AC in directly.
Would the cells stay in balance over these months?
Any suggestions? other best practices?
