Atem Power 12V 20A DC to DC Battery Charger MPPT System Kit Isolator Dual Battery

When you’re off the beaten track and main power isn’t an option, the ATEM POWER 12V 20A DC‑to‑DC Battery Charger is your ideal companion for a dual‑battery setup. Designed to handle a full charge cycle with selectable battery profiles (Lead‑Acid, AGM, Gel, Calcium, or LiFePO₄), it prolongs battery life and gives you flexibility. It even features a “Re‑selection Ready” mechanism—hold the POWER button to switch battery type while charging. Once everything is set up correctly, you can leave it connected indefinitely.

Perfect for overlanders, 4×4 enthusiasts, and off‑grid campers who need reliable auxiliary power in remote areas across South Africa.
