We recommend either a traction battery with a deep discharge cycle or a semi-traction battery. Preferably a gel or AGM Marine type battery (contents will not leak when tipped over). Recommended capacity 65 - 75 Ah (approx. 2hrs at max power). The battery charger should have the ability to switch for Gel, AGM, Normal batteries or be equipped with a microprocessor automatically controlling the charging cycle depending on the type of battery.
