Victron Energy Blue Smart IP22 Battery Charger 12V 30A

Take complete control of your battery charging with the Victron Energy Blue Smart IP22 12V/30A — a high-output smart charger with built-in Bluetooth, three independent outputs, and a fully automatic charging cycle. Charges a 300Ah battery bank from flat in under 12 hours.

Benefits:

• 30A output — fast charging for large battery banks up to 300Ah+

• Three independent outputs — charge up to three batteries simultaneously

• Built-in Bluetooth — monitor and configure via free VictronConnect app

• Supports lithium (LiFePO4), AGM, gel and flooded lead-acid

• Safe for permanent connection — intelligent maintenance mode

• AU/NZ plug included

• IP22 rated — suitable for dry indoor use

Features:

The Blue Smart IP22 12V/30A is the highest-output charger in Victron's portable range — ideal for quickly charging large leisure battery banks, fleet vehicles, or multiple batteries simultaneously. Three independent output ports allow you to charge separate batteries in different stages without interference. Built-in Bluetooth connects to the free VictronConnect app for live monitoring of voltage, current, and charge stage on each output. The fully automatic algorithm handles bulk, absorption, and float/maintenance stages. Select your battery chemistry in VictronConnect for the correct charge profile. Note: IP22 rated — for indoor dry installation only; for outdoor or wet environment use, see the Blue Smart IP67 12V/25A.

Frequently Asked Questions

How fast does the Blue Smart IP22 30A charge a campervan battery?

At 30A output, a 100Ah lead-acid battery charges from flat in approximately 4–5 hours (absorption stage included); a 200Ah battery takes around 8–10 hours. Lithium batteries charge faster as there is no long absorption phase. For a 300Ah lithium bank, expect 5–7 hours from a low state-of-charge to full.

Can I charge three different batteries at once?

Yes — the IP22 30A has three independent outputs that can each charge a separate battery simultaneously. The 30A total is shared across the three outputs, so with three batteries connected the available current per battery is reduced. Each output manages its own charge stage independently — useful for a workshop environment or charging a starter battery, leisure battery, and a spare in one session.

Is the IP22 charger suitable for lithium (LiFePO4) batteries?

Yes — select the LiFePO4 profile in VictronConnect. The charger will use the correct charge voltages and terminate at the end of absorption without entering a float stage, which is the correct approach for lithium chemistry. Always use the lithium preset rather than a lead-acid preset for lithium batteries.
