Victron Blue Smart IP65 12V 25A Battery Charger

The Victron Blue Smart IP65 is a 12V 25A charger with built-in Bluetooth and a NEMA 1-15P plug, rated IP65.

Twenty-five amps is the high-output IP65, well above the 8A and 13A models, which makes it the one for a battery that gets properly drawn down rather than merely maintained. A charger sized to the bank matters in both directions. Too small and it never finishes overnight; too large and it pushes current a small battery cannot absorb.

IP65 construction resists dust and water spray, so the charger works in a cockpit locker, a garage or a yard rather than needing a dry protected position. That suits a portable charger moved between a boat, a vehicle and a workshop, which is how most chargers of this size are actually used.

Bluetooth through VictronConnect gives charging status, battery data and settings from a phone or tablet rather than a row of indicator lights. Adaptive multi-stage charging handles routine maintenance and deeper recovery, with a lithium mode available for supported batteries. Explore more battery chargers.
