Off-grid Engineering no longer makes dual battery kits for Toyota Trucks. So, we do not have these in stock or have access to them anymore. We do build custom one-off kits here at the shop, but we do not ship them. Contact us for more details.

Off-Grid Engineering makes the best dual battery system for Toyota vehicles. We’ve had several of their systems in our vehicles, and they are functional works of art.

If you’re looking to add more power under the hood, Matt’s system is the best option available on the market, plus it’s made right here in the USA. We offer sales and installation of all Off-Grid systems and can help choose the right one for you. Contact us for more information.
