ProMariner ProNauticP 1230P 30 Amp 3 Bank Battery Charger

The ProMariner ProNauticP 1230P is a 30A three-bank charger for 12V marine battery systems.

Thirty amps sits between the 20A and 40A ProNautic models, which is where most boats actually land. It brings banks back faster than a maintainer without the cost and current draw of the 40A unit. Charger output should be matched to bank capacity rather than bought as large as the budget allows, since an oversized charger stresses a small bank.

Distributed-On-Demand directs available current to the bank that needs it most, which lets 30A do more useful work than a fixed-split charger of the same rating. Selectable profiles cover flooded, AGM and gel, with automatic conditioning, maintenance and periodic reconditioning built into the cycle.

Auto-ranging 100-250V AC input with power factor correction handles a wide range of shore supplies. Dual digital displays show charging voltage and current in real time, and separate fault indication flags wiring or bank conditions needing attention. Explore more 3-bank battery chargers.
