200ah 12v lithium smart battery + dc-dc charger

Hi All,

Does the 200ah 12v lithium smart battery require a dc-dc charger if you're also connecting it to the 200/12 BMS?

It doesn't show any requirements for a dc-dc charger in the installation manual.


Thanks in advance

Ryan

The BMS does not implement a charge profile for the batteries, just protection against over/under voltage and over current, and possibly low temperature charge cutoff.

A DC-DC charger is necessary to properly charge an LFP from a vehicle's engine electrical system (alternator). The charger will prevent alternator overload and also provide the proper voltage and current for the LFP battery.
