The Pro Charge B charger puts a load on the alternator and converts that load into a 4 stage charging profile to provide fast and effective charging to the leisure/domestic batteries. The whole point of the charger is to charge your batteries up when you drive/cruise along by fully utilizing your onboard alternator. The charger is best suited for outdoor use to fully utilize its weatherproof casing. Therefore, it tends to be at home on bass fishing boats charging the trolling motor bank – it can be used in a plethora of other places.

Why choose Pro Charge B Waterproof Battery to Battery Charger (built to IP68)?

Not only does the charger connect the 12V starter battery to the trolling motor bank it also chargers them at their correct voltage scale and profile. This encourages the alternator to work at a much higher capacity and results in faster charge between fishing stops and better maintenance of your trolling motor batteries.

Bass Boat Charging

Why not charge the bass boat batteries while driving along? Connect a Pro Charge B from the truck starter via an Anderson type socket at the back of the truck to the Prime Wiring setup. This example allows you to fast charge while driving to and from the lake and then while cruising on the lake.

Shore Power

Shore Power Charger (AC to DC). Directing shore power to the engine starter battery shall activate the Pro Charge B to charge the trolling motor batteries at their correct profile at 12V / 24V / 36V / 48V.

Alternator Charging

Charging performance of alternator or magneto without a Pro Charge B will produce about 1-2A. With a Pro Charge B, you can expect the output from the charging source to run at a much higher rate – up to 25A at 12V. Larger alternators do not adversely affect the product as its current limiting.
