Ultimate Smart Battery Switch System
This complete marine battery switch system automatically selects which of your batteries charge while you are underway - and which get tapped when you play!

Smart Battery Switch System
Arrives complete and ready to install with:
- Voltage Sensitive Relay from BEP/Marinco
- Dual Pole Plus Battery Switch from Blue Seas
- Marine electric battery cables - Two red and two black, both 4' long with 3/8" tinned copper terminals
- VSR cables - Two 8" long, Red 8 AWG cables with proper terminals
- Terminal boots - two red molded from high temperature vinyl
- Marine electrical ground bus - BEP Dual Post with tinned copper studs for added corrosion resistance
The heart of this ready-to-install marine battery switch kit is a clever relay that automatically combines your starting and trolling/house batteries - so both are being charged - whenever sufficient voltage is available.
Then, as you use power, whether running trolling motors, stereo, anchor lights, or other accessories, the same marine electric relay that conected your batteries for charging now unlinks them so you are only draining one - leaving the other with the starting power you'll need later.
Eliminate those "mysterious" drains in your boat wiring that can cause dead batteries while you're not using your boat. The included battery switch allows you to easily shut off your boat's power when you're away.
