BATTERY ISOLATOR (PRO MARINER)

Rated for 70 amps maximum alternator. Operates on 6, 12, 24 & 32 volt negative ground systems. Electrical current able to flow from DC source to batteries in one direction only. Allows one or two devices (depending on isolation model) to charge multiple battery banks without the banks being connected. NOTE: All isolators impose a .6 volt drop in the circuit.
From $64.99

BATTERY ISOLATORS (SIERRA)

Battery isolators allow you to charge multiple batteries from a single source.
* Will not work with Delco "CS" style alternators.
From $59.68

BATTERY ISOLATORS MATE IG (MASTERVOLT)

The Battery Mate is the ultimate solution for charging several batteries simultaneously and is compatible with any type of alternator/battery charger, in both existing and new systems. Performs far better than conventional battery isolators. This ensures fast and complete charging of your batteries without having to make additional adjustments to the alternator. Its components compensate for variations in voltage and ensure that charging continues at the right voltage level, even with several battery banks. The input side is connected to the alternator and/or battery charger, while two batteries are connected to the output side. Easy to install on a DIN rail (industry standard).
