A TRUE®  exclusive!

All the TRUE® dual battery kits have proprietary cables that use adhesive-lined shrink tubes to maintain their anti-vibration and corrosion-proof properties.  All Ford F-150 model is offered in 7 trim levels: XL, XLT, Lariat, King Ranch, Raptor, Platinum and Limited are applicable to our True® battery isolator system.

The True® F150 dual battery kit is a system designed to provide a reliable and efficient way to manage the batteries that power accessories and appliances in a vehicle while maintaining the starting power of the main battery. It consists of two batteries connected in parallel with an isolator that separates the batteries when the engine is turned off, preventing the auxiliary battery from draining the main battery.

The True® dual battery kit is typically used in off-road vehicles, boats, and recreational vehicles where there is a high demand for power to run various accessories such as winches, lights, refrigerators, and communication devices. The kit ensures that the accessories can be powered without draining the main battery, which could leave the vehicle stranded or unable to start.

  1. DFNA

    I’m a novice radio operator, and I use a home lithium battery to power the radios. The only way I could get my 2011 F-150 to charge both batteries without causing a problem with the battery management system.

    Furthermore, lithium cannot be paralleled with a flooded AGM or flooded lead acid battery; they must be separated. I tried a variety of approaches without success until I tried the Smart Isolator. And it works perfectly, keeping both the start battery and the lithium home battery completely charged.
