When I'm plugged in my battery will not charge fully but that is not a problem with lithium.
be careful saying that. yes, I agree it doesn't have to be charged fully on a regular basis, but you still have to charge it full once and a while to ensure the cells stay balanced.
You can get away with this because you let your solar charge it with proper profiles and hopefully you take it up to 100% with that once and a while and let it fully balance. My BMS has a passive balancer that would take forever to balance so I added an active balancer to mine, so it only needs 2 hours or less to balance my 300AH battery. When I am camping, I do this once a week, the rest of the time I cut off at 90% but that's the BMS controlling that.
