Perfect chargers for any type of battery, the Victron Skylla Battery Charger 24v 100A has one full rated output and one 4 Amp output. The 4 Amp output is intended to maintain an engine start battery. This output is provided by a separate charging circuit to the main outputs. It is a constant voltage float charge output only, to prevent overcharging the engine start battery. The charge voltage can be precisely adjusted to suit any battery system whilst the input for the charger is 90-265VAC at 50/60HZ. Charge voltage can be measured directly on the battery terminals in order to compensate for voltage loss due to cable resistance. An external sensor allows to measure battery temperature and compensate charge voltage accordingly. Suitable for AC and DC supply (AC-DC and DC-DC operation) the chargers also accept a DC supply. Every TG Charger has a microprocessor, which accurately controls the charging in three steps. The charging process takes place in accordance with the IUoUo characteristic and charges more rapidly than other processes. In order to compensate for voltage loss due to cable resistance, TG Chargers are provided with a voltage sense facility so that the battery always receives the correct charge voltage.
