Battery disconnect relay
Would you like to charge more than one battery at the same time with just one power source? Then a battery isolator relay is just what you need. Thanks to its advanced technology, it efficiently distributes the charging current to up to three batteries at the same time without losing voltage. At Offgridtec, you will find the perfect 12V or 24V battery isolator relay for your needs. Browse through our online shop now and see for yourself!
Types of battery disconnect relays
A relay is an electrical switch with two positions. It is used, for example, in motorhomes to separate the on-board and starter batteries when stationary and to connect them for charging. Depending on the design and function, you will find a range of useful battery accessories in our online shop, as well as two different types of isolator relays:
- simple
- automatic
Simple isolator relays require a switching signal from the alternator (or another power source), while a fully automatic battery isolator relay connects the batteries as soon as one battery reaches 13.7V and disconnects them as soon as one battery drops below 12.8V.

FAQ
- What does a battery isolator relay do? A battery isolator relay allows several batteries to be charged simultaneously from a single power source without the batteries being connected to each other. As soon as one of the two reaches 13.7V, the isolator relay switches on so that both batteries are charged at the same time.
- Which terminal must be connected first when installing the isolator relay? The red cables are connected to the positive terminal first, followed by the black cables to the negative terminal of the battery.
- How do I charge the starter battery in my motorhome? A disconnect relay or a charge booster can be used to charge the starter battery while driving. This connects both batteries in parallel and ensures that both batteries are charged via the alternator.
