You love going off-road, but you’re tired of your battery dying on you. You’ve been thinking about installing a dual battery system, but you’re not sure how to go about it. This article will show you how to install a dual battery system in your vehicle, so you can keep going off-road without worry.

Let’s dig into it and see what we can learn.

Step by Step Procedure for Installing A Dual Battery System In A Vehicle.

1. Decide on a mounting position for the second battery in your engine bay.

2. Super cheap auto cell battery trays and all necessary accessories formatting your second battery.

3. Just be careful to ensure your battery kit has enough wire to reach the second battery.

4. Disconnect the negative terminal from your main battery before starting any work.

5. The voltage-sensitive relay or VSR is the computer controller for the two batteries and needs to be mounted where it will be easily accessible away from any hot or moving parts and as close to the main battery as possible.

6. Use the mounting plate on the back of the VSR to mark and drill four holes and secure the top right and lower left holes with the short screws.

7. Take the length of red cable with lugs at both ends and measure out enough cable to run from the center of the mounting plate to the positive terminal of your main battery.

8. Follow the existing wiring where possible and avoid hot or moving parts.

9. Cut the cable length and repeat this step this time to the positive terminal of the auxilary battery.

10. Now we fit the lugs to the bare ends of the cable by stripping away 15 millimeters of insulation and crimping them in place with the crimping tool.

11. Slide the heat shrink over the lug and heat it with a heat gun to give it a waterproof seal.

12. The black wire attached to the VSR needs to be earthed. It’s important that these earths are grounded securely where possible. Use a bolt which has been used to earth the engine or other engine component.

13. The cable from the main battery goes to the VSR terminal marked with a red dot and the words positive sense battery. The cable from the auxiliary battery goes to the terminal mark with the words positive second battery.

14. Your second battery will need a solid earth as well.

15. Take the 24 inch black earth cable and again secured to a factory engine ground or similar.

16. The VSR can now be attached to the mounting plate using the two longer screws and the positive cables may be attached to the main and secondary batteries.

17. Then secure the negative terminals first to the main battery and then to the auxiliary battery.

18. Use the cable ties supplied to keep your wiring neat and safe.

19. If you want to test your new setup you can do so with a multimeter.

20. Start the vehicle’s engine and take a reading from the main battery. Once the voltage climbs above 13.3 volts you should hear the relay click and the red light illuminate to show that the second battery is connected.

21. Now turn off the engine and take a reading from the main battery again. Once the voltage falls below 12.8 the relay should disconnect.

22. To speed up this process you may wish to switch the headlights on.

23. If everything works as per these tests you’ve successfully installed your own dual battery kit!
