The upgraded dual power supply isolator adopts imported power management chips, and has relatively novel electronic circuit intelligent automatic management functions. It also has the characteristics of strong waterproof, low loss, good heat dissipation and high efficiency.
Instructions for use: When the voltage of the main battery is greater than 13.3V, the main battery charges the auxiliary battery; when the voltage of the main battery is lower than 12.7V, the main battery and the auxiliary battery are disconnected.
Prevents you from draining the starter battery.
Automatically combines two batteries when charging and isolates the two batteries when not charging.
Suitable To Install into Camper Van, 4x4 car, Leisure Vehicles & Marine
