Essential for dual battery setups
I installed this in my van to manage the starter and house batteries. It works flawlessly, combining them when charging and separating when the voltage drops. Couldn't be easier to wire. Highly recommend.

Great product, fast shipping
This little relay is a gem. I have a 4x4 with dual batteries and this handles the charging separation automatically. The build quality is top-notch, typical Victron. Install was straightforward with the included wiring diagram. I like that it has a low current draw and doesn't generate heat like some other combiners I've seen. For the price, it's a steal. My setup has been working flawlessly since I installed it.
