Precision charging algorithms help extend the life of your auxiliary battery. The charger delivers multi-stage charging tailored to the battery type, helping maintain peak performance over the long haul.

Starter Battery Isolation

To protect your starting battery, the charger only delivers current to your auxiliary battery when the engine is running, and automatically disconnects when the vehicle is off – eliminating unwanted drain.

Supports Multiple Battery Chemistries

Whether you’re using lithium, AGM, wet, gel, or calcium batteries, this charger has you covered. It’s a versatile solution designed to support a wide range of battery types.

Perfect for 4WDs, caravans, camper trailers, and off-grid touring setups, the KickAss 40A DCDC Charger with Solar MPPT and Bluetooth delivers intelligent charging for serious adventurers.
