Victron Blue Smart IP22 12V 15A 1-Bank Charger

The Victron Blue Smart IP22 is a 12V 15A single-bank charger with Bluetooth, for dry protected installations.

The recondition stage in the six-step process is worth understanding, because it does something the other stages do not. It applies a controlled overvoltage to a flooded lead-acid battery to mix stratified electrolyte and reverse light sulfation. That recovers capacity a straight bulk-absorption-float cycle leaves lost.

It is not appropriate for every chemistry, so the charger tests the battery first and selects behavior accordingly. Storage mode then lowers long-term float voltage after extended periods without discharge, reducing gassing and corrosion.

Fifteen amps suits a single moderate 12V bank rather than a large house bank needing overnight returns. Bluetooth gives wireless access to voltage, current, charging status and settings, and NIGHT and LOW modes reduce output for quieter or lower-demand charging. Explore more battery chargers.
