Much info here for RVers too not just boaters, covering many of the things discussed on this forum. Eg warnings about BMS amp rating vs battery AH size, charging--beware of charger absorption tim...

Perry,
The only reason to charge to 100% with Li is to "reset" the battery management system and "balance" the cells. Once a month appears to have several votes.
Every thirty days to 100% is what is recommended for SiO2, but for entirely different reasons.
I would also add here, to allow for shunt meter re-synchronization…The ‘once a month’ to 100% idea is not a driving factor - the number of less than full charge cycles is…
Multiple up and down charge cycles of say less than a full 100% can over-time result in small amounts of cumulative meter drift…Meter re-synchronizations AND periodic cell-balancing present the need for an occasional re-charge to 100% SOC, followed thereafter by a brief holding period to accommodate cell re-balancing…
When camping (after such…) my preference is to aid battery longevity by then shutting-off ALL charging (this, to refrain from holding the battery at 100% SOC)…Thereafter, harvest is used to stay within a workable up and down range of somewhere between 10-90% SOC…JMO
