Behind-Seat Dual Battery System


Ultimate Solution for Utes & Dual Cab Vehicles

This is the ultimate solution for Utes and Dual Cab vehicle that can’t fit a battery under the bonnet. We have engineered a complete dual battery system that can fit behind the rear seat.

We are excited to announce that we are offering Lead Crystal® Batteries and Lithium Batteries as an option for powering an In-Cab Dual Battery System for your Ute or Dual Cab vehicle.

For the ultimate performance system, we can fit a Lead Crystal® 100 Ah battery, or Lithium Slimline Battery, a Redarc BCDC, an 8 circuit fuse box, Solar input and Anderson connected to your charge system to charge the battery while you’re driving (check out the photos below)

This solution is perfect as it mounts behind the rear seat and is wired to your charge system to charge the battery while your driving. We can also run cable to plugs or sockets anywhere in the vehicle to power any of your devices (fridges, work lights etc.) 

We are thrilled to announce that our Behind-Seat Dual Battery Systems are now available to purchase as a kit that you can install yourself. For more information and prices, visit our online store here: Behind-Seat Dual Battery System Kit

Why Choose Lead Crystal® Batteries?

Better Usage Performance

Charges faster to 90% than conventional alternatives. Excellent high-current discharge ability. Suitable for Solar cycling/ boost charge applications. No equalisation cycles required. *Partial State of Charge boost may be required but less frequently than conventional batteries. 

Full Recovery

Can be 100% discharged and then restored to full rated capacity daily. The battery can be recovered from 0V 100% discharge with high voltage maintenance cycles.*Reduces battery life in this mode of operation.

Long Battery Life

Float service life up to 18 years. Up to 6000 charge/discharge cycles (20% DOD). Extended life at higher temperatures, with only 23% life loss at +40°C.

Long Shelf Life

Can be stored for 2 years with no refresh charging required. Very low self-discharge loss at 25°C

Extreme Temperature Resistance

Operates at temperatures from -40°C to +65°C with just 13% life loss for every 10°C, compared to 50% for every 8-10°C on Lead Acid/ GEL


Up to 99% recyclable and increased sustainability. With most components including the SBS casing suitable for recycling and only the electrolyte bearing Super Absorbent Mat (less than 1% in volume) for disposal.


Less acid, no cadmium or antimony. Complies with increasingly strict international standards on protection of the environment.


No risk of leakage, less harmful chemicals, less fluids because of crystallization. Even if the casing is compromised, with the electrolyte crystallizing, the battery will not leak and can continue to work.
