Benefits of running a dual battery system:

If you are someone who goes or is planning on going on 4x4 camping trips (overlanding), then you will need auxiliary power. A dual battery system is where two separate batteries are working in conjunction with each other. Running our secondary battery kit will ensure your Toyota 4Runner has start-up power.

  • Why we use the Blue Seas ML-ACR in our kits?
  • The Blue Seas ML-ACR is a fully self-contained automatic charging relay that automatically connects the batteries during charging state and disconnects when not. The ML-ACR is capable of handling the total current capacity of the second battery. By isolating the second battery and using the main battery for all accessories loads, you have the peace of mind of not being stranded due to a dead battery. Even with an entirely dead main battery, simply pushing the switch on the ACR, you will be able to self jump-start the vehicle. The ACR also allows total current from the alternator for charging, along with the option of manually locking the batteries for tasks such as winching.
