Improve Charging Efficiency with ProMariner 70 Amp Multi Battery Isolators for Marine, RV, and Automotive Use

ProMariner Multi Battery Isolators, featuring gold-plated terminals for improved conductivity, are designed to enhance charging efficiency while preventing the total discharge of your starter battery. These solid-state devices ensure electrical current flows in one direction, allowing energy from the alternators to be distributed evenly across multiple batteries. This setup enables simultaneous charging of multiple batteries while isolating each one during operation, preventing fully charged batteries from discharging into undercharged ones.

These isolators are ideal for systems with one or two alternators connected to multiple battery banks, ensuring reliable power distribution without the risk of draining fully charged batteries. Designed for use with negative ground alternator systems, they are not recommended for use with self-energizing alternators. The ProMariner Multi Battery Isolators provide peace of mind by maintaining efficient power flow and battery protection in marine, RV, and automotive applications.
