DOWNLOAD INSTRUCTIONS HERE: 79 Series Installation Instructions 

The team at Accelerate have answered 79 series owners prayers and have been busy designing our brand new Behind The Seat Lithium Dual Battery Kit.

After going back to the drawing board we have finalised this long awaited DIY Dual Battery Kit. 

This kit has already been installed and tested in multiple vehicles in our workshop in Maroochydore on the Sunshine Coast.

This DIY kit has everything you need to install the kit into your 79 Series, including step by step instructions. OR you could have it professionally fitted here in our workshop at Maroochydore. 

This is the perfect way to utilise the wasted space behind the seats in the 79, whilst still retaining full function of the seats.

The 100Ah Invicta Slim Lithium battery or 100Ah Enerdrive Slim Lithium Battery provides the perfect amount of power to be able to keep a fridge running, phones charged and strip lights on during the night* and then get a full charge from the REDARC BCDC within two hours of driving*.

With the addition of solar input you can stay off grid for days with this compact and durable battery kit!
