Drop in a vehicle I can see, but to hook it to a charger mean for LA's (or other) sounds counter productive. My understanding is the Lipo will never reach full capacity, the charger will go into float before it reaches.
Again, opinion, not fact.
The BMS Manages the charge by limiting the voltage and current depending on what is going on with its input and the state of charge on the battery, but I do not think it steps up a voltage it sees on the input (like 13.6V from a SLA charger to 14.4 on a LifePo4). That would require a DC to DC converter and I don't believe the typical BMS has that function.
A DC to DC battery charger does that. It takes a bit of circuitry to achieve that.
