Votronic Switch Unit 100 12/24V Battery Main Switch
Switch Units are working on basis of a bistable relay allowing very high capacities combined with a very low own consumption. They suitsespecially as a remote-controlled main switch or load relay which is on long-term power. The current carrying capacity conducts 40 A or 100 A.
Switch Units can be mote-controlled by a normal switch (1 pol. ON / OFF).
Furthermore the consumer can be switched on and off through an emergency switch at the relay by hand.
The ranges of application are campers, intervention vehicles and boats:
Easy selection through ON / OFF switch
High switching current, short time loadable
Applicable as battery main switch through ON / OFF switch (remote-controlled)
Switching state monitor is visible from the outside
Electronical delay prevent fast reactions like voltage drop or using strong consumer
Suitable for long-term usage due to a very low consumption of the Switch Unit (compliant EN13976)
No own electricity consumption if switched off with an external switch (remote-control)
Automatical disconnection by under voltage 8.5 V (minimum operating voltage of Switch Unit)

Victron Argo FET 100-2 100A Battery FET-Isolator
The Victron Argo FET-isolator 100-2 (MPN ARG100201020R) allows the supply of 2 separate battery circuits with up to 100A charging current via one power source. This source can be the alternator or a charger.
As the single battery banks are not connected it is not possible that they discharge or affect each other. The difference between isolators and FET-isolators is that FET-isolators barely generate any voltage losses and therefore are much more efficient.
Features:
max. charging current of 100A and connectors for 2 battery circuits
with 0.02V at low and 0.1V on high currents there is only a very small voltage loss which makes a compensating voltage increase unnecessary
proven Victron quality with a guarantee of 5 years
Only small voltage lossesCompared to common isolators there are only very small voltage losses with FET-isolators - only 0.02V at low and 0.1V on high currents. With Argo FET-isolators there is no voltage increase necessary. You should still keep an eye on short cable lengths and sufficient cable diameters.
Example: A current of 100A at a cable length of 10m and 50m² cable diameter has a voltage loss of 0.26V. At a cable of 5m and 10mm² a 50A-current generates a loss of 0.35V! That's why FET-isolators belong to the most efficient charging current distributors on the market.

Mastervolt Charge Mate 2502 battery separator relay
A secondary battery is becoming increasingly common. As a second battery can prevent the main battery from depleting and being unable to start, this seems like a safe and reliable solution. The second battery, however, also has to be charged regularly. The Charge Mate series connects both batteries during charging and keeps them isolated when discharging. The Charge Mate 1202 and 2502 are especially practical for small systems.

Battery Isolator Relays
You want to charge more than one battery at the same time with only one power source? Then a battery isolation relay is just the thing for you. 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 perfectly suitable 12V or 24V battery cut-off relay for your needs. Browse through our online shop now and see for yourself!
Types of battery cut-off relay
A relay is an electrical switch with two positions. It is used, for example, in motorhomes to separate the on-board battery from the starter battery when stationary and to connect them for charging. Depending on the design and mode of operation, you will find two different types of isolating relay in our online shop, in addition to a range of useful battery accessories:
- simple
- automatic
The simple disconnect relays require a switching signal from the alternator (or other power source), while a fully automatic battery disconnect relay connects the batteries as soon as a battery reaches 13.7V and disconnects them as soon as a battery drops below 12.8V.
Buy best quality battery disconnect relay online at Offgridtec
At Offgridtec you will find both simple and electrical cut-off relays in top quality and at the best prices. Our experts only select high-quality products from renowned manufacturers for our online shop and will be happy to answer any questions you may have about our products.
We will be happy to advise and support you in finding your suitable battery cut-off relay. You can reach us on +49 8721 91994-00 to take advantage of our expert advice for private customers and specialist dealers. We are also happy to receive an e-mail at [email protected]!
FAQ
- What does a battery disconnect relay do? With a battery cut-off relay, several batteries can be charged simultaneously from one power source without the batteries being connected to each other. As soon as one of them reaches 13.7V, the cut-off relay switches on so that both batteries are charged at the same time.
- Which pole must be connected first when installing a cut-off relay? The red cables are connected to the positive terminal first, the black cables then to the negative terminal of the battery.
- How do I charge the starter battery in the motorhome? An isolating relay or a charge booster can be used to charge the starter battery while driving. This switches both batteries in parallel and ensures that both batteries are charged via the alternator.
