Victron Energy Skylla-TG Series Battery Charger 24V 80A.

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.
