This Add-A-Battery kit is designed to facilitate adding a dedicated starting battery to any vehicle or boat. The intention is to keep the starting battery reserved for starting. The switch turns on both the starting and house battery simultaneously but keeps them separate from each other. The Automatic Charge Relay ensures that both batteries get charged simultaneously.

Answer provided by: Peter Kennedy (4/9/2018)

A: If the two house batteries are wired together as one then the switch will see them as just one bank and work just fine. Its not designed for a Start Battery and two separate house batteries where you get to choose house battery 1 or house battery 2

Q: Should the light be green all the time if all is ok or should it not be lite up sometimes ?

Asked by: John kelley - 4/29/2016

A: The light is on when the combiner is combined. Once the charge source is removed the battery voltage will slowly drop and after a while the combiner will separate and the light will go off.

Q: Can this be used to add a second battery to an SUV if I also plan to install a solar panel and may upgrade the alternator to 165 amps as well.

Asked by: Bill - 5/12/2020

A: It certainly can be used in a motor vehicle, these get used in RV's all the time. This model has a maximum rating of 120 amps so if you upgrade your alternator to 160 Amps that would exceed the rating. We have other models available with higher ratings.
