It is well suited to battery sizes up to approx. 300Ah and can maintenance charge the battery for an unlimited time. The charger can stand parallel charging up to 17A parallel consumption at the same time as it charges the batteries. The charging voltage is temperature compensated with external sensor, except for chargers with LiFePO4 charging curve.
DEFA MultiCharger/MarineCharger/RescueCharger 2x20A has two separate charge outputs and each output has a separate temperature sensor and remote LED.
To satisfy customers with different needs the charger comes without a fixed charging cable. This has to be obtained separately and there are several different lengths available, as well as remote LED panel. See accessories list below.
