Sizing & Settings

Choosing the Right Victron Charger

Size an AC charger at roughly 10–25% of battery capacity in amps — a 15–20A Blue Smart suits a 100Ah AGM or LiFePO4 bank well. Blue Smart chargers pair via Bluetooth for LiFePO4, AGM, and storage-mode settings; the Smart IP43 line adds multi-output models for charging two or three banks plus a starter battery. For vehicles with smart alternators, choose an Orion-Tr Smart or Orion XS DC-DC charger; the BuckBoost variant handles wide input ranges on Euro 5/6 systems. All Victron chargers use adaptive multi-stage charging (bulk, absorption, float), and all adjust charge profiles in VictronConnect for safe LiFePO4 charging.

Which Victron battery charger should I buy?

Pick a Blue Smart or Smart IP43 for shore-power charging, an Orion-Tr Smart or Orion XS for alternator charging, and a Centaur or 3-output Smart IP43 for multi-bank boats and RVs. Match output amps to roughly 10–25% of bank capacity.

How long will a Victron charger take to charge a battery?

Divide usable capacity by charger output, then add 1–2 hours for absorption. A 100Ah battery with a 20A charger typically charges in about 6–7 hours.

What settings should I use to charge LiFePO4 batteries?

In VictronConnect, select the LiFePO4 preset — typically around 14.2–14.4V absorption and 13.5V float for 12V banks. Check your battery manufacturer's specs and set them in the charger's expert settings.
