Add a Battery kit
Simplifies switching and automates charging for a 120A two battery bank solution for inboard and outboard powered boats.
For alternators up to 120 amps.
Simple to operate as an ON/OFF switch, yet effectively manages the switching and charging of two batteries from a single charge source.
Includes a Blue Sea #5511E e-Series Dual Circuit Plus battery switch and a Blue Sea #7610 automatic charging relay.
Dual Circuit Plus battery switch features:
- simplifies switching
- isolates engine and house circuits
- combines batteries for emergency starting
- tin-plated copper studs for maximum conductivity and corrosion resistance.
Automatic charging relay features:
- automatically combines batteries during charging
- isolates batteries during engine cranking and when not charging
- shares the charge between two batteries more efficiently than a battery isolator
- allows efficient dual battery charging without needing regulator adjustment or rewiring.
