Battery Management System275 Amp (LARGE)

Ironman 275 Dual Amp Battery allows for simultaneous charging of two batteries.

After starting the engine and main battery, when the voltage rises to 13.7V, the module activates, allowing two batteries to charge simultaneously.

When the voltage drops below 12.2 V (e.g. engine is off), the system disables battery charging.

Included monitor displays voltage levels of both batteries.
