Hardkorr Heavy Duty Battery Box Pro w/ 40A DC-DC Charger
Portable Power Station with Built-In 40A DC-DC Charger
The Hardkorr Heavy Duty Battery Box Pro w/ 40A DC-DC Charger takes the already-impressive Battery Box Pro and adds a fully integrated 40A DC-DC charger with MPPT solar regulator — so you can charge your auxiliary battery from your vehicle's alternator or a solar panel without any extra hardware.
Whether you're parked up at Wallaman Falls, camped at Undara, or working the Savannah Way, this battery box keeps your power topped up automatically. Simply connect via Anderson plug to your starter battery circuit and the 40A DC-DC takes care of the rest — with intelligent multi-stage charging that's compatible with Lithium LiFePO₄, AGM, Calcium, Wet, and Gel batteries.
