T-Max Dual Battery System

Description:
The T-Max 12V Dual Battery Isolator Kit is designed to give you reliable power control when running dual battery systems. Ideal for 4x4s, off-road vehicles, campers, RVs, and overlanding rigs, this intelligent system automatically connects and disconnects your main and auxiliary batteries to prevent starter battery drain.
It allows both batteries to charge from the alternator when the vehicle is running and isolates them when the engine is off — ensuring your accessories never leave you stranded.
