Long recoveries requiring your Jeep provide electricity to a high power winch and high wattage driving lights are a real suck on your Jeep battery. The smart jeeper has an auxiliary battery just for this reason. The smart Jeeper also shops at 4WD for the dual battery tray on which to mount the primary and auxiliary batteries stacked one atop the other or side by side. Battery trays on 4WD provide you with multiple mounting options and all come with mounting hardware and many also include tie downs. 4WD features battery trays from top off-road brands such as Smittybilt, Mountain Off Road Enterprises and Trail Gear.
