PAC Dual battery isolator up to 16.5 Volts handles 500 Amps continuous and 700 Amp surges
The PAC-500 handles 500 amps continuous and 700 amp surges. Durable weatherproof construction. A must for multi-battery systems, allows for longer battery life and control over which battery is being used.
Great for isolating second battery in boats making it dedicated only to the stereo system. Keeps primary starting battery from being drained to the point of stranding you in the middle of lake, river or ocean. Unlike Dual Battery Isolators, the PAC-500 does not create any voltage drop to the secondary battery.
