Mean Mother 20 Amp DC-DC & MMPT Solar Charger

The Mean Mother 20Amp DC-DC Battery Charger is a sophisticated multi-stage charger, designed to

charge AGM, GEL, Lead Acid, Calcium and most deep-cycle batteries (does not include lithium batteries).

Ideal for charging dual / secondary batteries, campers, caravans and portable battery packs while driving or via solar (without requiring an external solar regulator).

• TROUBLE SHOOTING TIPS
• To change the battery tyre – You must do this before the second battery is connected. Once the second battery is connected to the unit, it virtually locks the setting/type.
