Same charger as the 20A model with half again the output. On a larger house bank that difference is the difference between an overnight charge and a two-hour one.

Matching charger to bank

The usual guidance is to charge at 10–20% of the bank's capacity. On a 200Ah lithium bank that is 20–40 amps, so 30A sits right in the middle. On a 300Ah bank you would want this or larger. On a 100Ah bank the 20A unit is plenty and this is more than you need.

Charging too slowly is not harmful, just slow. Charging a lead-acid bank too fast is harmful, which is why the chemistry setting matters.

Set for your chemistry

Bluetooth and VictronConnect. Pick AGM, gel, flooded or lithium and the charger uses the right voltages for each stage. Storage mode drops to a maintenance voltage if it stays connected for weeks, so you can leave the vehicle plugged in between trips without cooking the battery.
