OptiMate DC-DC 12V Battery Charger & Optimiser OPTDC

Maintain your battery where mains power can’t reach. The OptiMate DC-DC draws power from a charged 12V source battery to recover, charge and maintain another compatible battery, making it a practical option for storage locations without an AC supply.

Its fully automatic six-step programme adapts to compatible lead-acid and LiFePO4 lithium batteries, delivering a constant 2A charging current. Source battery protection provides a low-battery warning and automatic shut-down to help prevent excessive discharge of the battery supplying the power.
