This has been covered already. BMS is there (or should be) as a last line of protection not the first.
"Float" if used in a daily cycling of the batteries won't hurt it but if your going to float them at storage for long periods of time then it could shorten the battery life.
I dont think I would have a issue using a BMS to control the upper limit if it only shut down the charging but I dont know for sure if thats how the bigger ones work. I would rather use somthing like a smart shunt and capacity counter to shut off the charger automaticly when the battery is full and reconect when power is available if capacity is less than say 80%.
hmmm... could be another project in the making...
