On my ship the distance between the charger/batteribanks and the
windlass is about 10 meters. So my solution is to store the batteries to the
windlass together with the
windlass. Thus the cables from the battery to the
windlass are only a foot long. In the box, under the
windlass where the batteries are stored, I also store a separate 18 amp/220 volts charger. The 1500 watt (pure sinus)
inverter delivers the current to this charger. With this arrangement the current is transported from the
inverter to the charger of the
windlass batteries in 220 volts, and the cables are accordingly the standard for transporting 10 amp (in 220 volts, 1,5 mm2)
