• Weight, 0.9kg, with UK BS 1363 mains plug fitted as standard.

How it charges

The seven-stage adaptive algorithm adjusts to the battery's condition. A deeply discharged battery starts with a soft-start recondition phase, moves through bulk and absorption, then settles into float and long-term storage mode. Left on charge, it maintains the battery rather than overcharging it, which a fixed-stage charger cannot do reliably.

The VictronConnect app shows charge state, voltage, current and the selected battery profile, and lets you switch profiles or build a custom charge curve. Useful when commissioning a system or working out why a battery isn't taking charge as expected.

Applications

Suited to charging and maintaining 24V lead-acid or LiFePO4 banks in off-grid and backup power setups, workshop charging of 24V vehicle and plant batteries, marine use in enclosed battery compartments, motorhome storage charging, and system commissioning. The IP22 rating means it should stay dry, away from rain or condensation.
