Blue Sea P12 12V 25A 3-Bank Battery Charger

The Blue Sea P12 is a 12V 25A four-stage charger for three banks, accepting 90-265V AC, in a finned aluminum case for dry mounting.

PreFloat is the feature that distinguishes this from most multi-bank chargers. Each bank moves to float charging when it is ready rather than being held on the same timing as the others. Forcing three banks through one schedule means overcharging whichever finishes first, and PreFloat is what prevents that.

Charge Coordination works with compatible Blue Sea Automatic Charging Relays to control ACR state during charging, so each battery receives the correct float treatment rather than being combined at the wrong moment. User-defined profiles cover AGM, flooded lead acid, gel and TPPL, which is a wider chemistry range than most marine chargers support.

A large bright display gives diagnostic and operating information in English, French, German, Italian or Spanish. Protection covers AC over and under voltage, high and low battery temperature, DC over-voltage, reverse polarity, surges and short circuits, with automatic restart once an eligible AC fault clears. Ignition protected with a five-year warranty. Explore more 3-bank battery chargers.
