The preset voltages are intended for boats and vehicles where the engine is used for long periods of time and batteries are not often deeply discharged. If the shortest possible recharge time is required, the charge voltage can be increased by up to 0,3 V (12 V battery) or 0,6 V (24 V battery). If a high charge rate is required, always apply temperature compensation, which will lower the charge voltage as the temperature of the battery increases. Example: apply the AGM setting to charge Victron or Exide / Sonnenschein gel batteries.Always ask the advice of your battery supplier. 2. System voltage is adjustable. 3. System time is adjustable. 4. The charge cycle resets when the engine is stopped. 5. Delivery includes 1,3 meter cable harness. 6. Alternator Temperature Sensor is optional.

Charging more than one battery bank

An overview of the options: Victron Cyrix battery separator: microprocessor controlled relay that interconnects two batteries during charging. This is the simplest solution, which does not require any modification in the existing wiring.

Victron Diode or FET battery isolator: diode battery isolators allow simultaneous charging of two or more batteries from one alternator, without connecting the batteries together. Balmar Duo Charge: for charging a second battery, independently from the main battery. The Duo Charge has 4 built-in battery programs and a battery temperature sensing option. The maximum output is 30 A. Suitable for 12 V and 24 V systems.
