Victron Energy Skylla-TG IP21 Battery Charger 24V/80A/230V (1+1) - 1 Output - SDTG2400801 One full rated output and one 4 Amp output. Charge voltage can be precisely adjusted to suit any battery system. The input for the charger is 230V 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 measuring battery temperature and compensating charge voltage accordingly. PERFECT CHARGERS FOR ANY TYPE OF BATTERY Charge voltage can be precisely adjusted to suit any sealed or unsealed battery system. In particular, sealed maintenance free batteries must be charged correctly in order to ensure a long service life. CONTROLLED CHARGING 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. BATTERY VOLTAGE SENSE In order to comp
