Mount it securely in your boat's battery compartment for easy shore power access. Always match bank settings to battery types before plugging in—lithium banks charge quickest but need precise curves to avoid stress. For multi-battery rigs like house, starting, and house banks, this setup shines, balancing loads perfectly. In saltwater, rinse connections post-use to extend life, though its robust design handles spray effortlessly. Regular equalization on lead-acid batteries every few months keeps them peaking at 100% capacity.
Yes, each of the five banks operates independently, so you can charge lithium LiFePO4 on some, AGM on others, and flooded lead-acid on the rest—all safely and optimally.
Absolutely. Automatic temperature compensation adjusts charging rates based on ambient conditions, ensuring safe, efficient performance from freezing mornings to summer heat.
The digital microprocessor detects standby lithium batteries and applies a wake-up pulse, bringing them online without manual intervention for hassle-free starts.
Designed for it—fully waterproof, vibration-resistant, and saltwater compatible, with ring terminals that resist corrosion for long-term reliability.
Most 12V batteries recharge fully in 4-6 hours at 10 amps per bank, thanks to multi-stage control that prioritizes speed without compromising safety.
Yes, it switches to float/maintenance after full charge, keeping batteries topped off indefinitely without overcharging—perfect for storage between trips.
They display real-time status: charging phase, full charge, errors, or maintenance mode, so you always know what's happening at a glance.
On-Board Precision Charger MK-550 PCL 5 Bank x 10 AMP LI Optimized Charger
Longer run times. Shorter charge times. That's the precision difference that keeps anglers on the water longer and puts more fish in the boat. Now, the next generation of this legendary line of chargers has been optimized for 12-volt lithium (LiFePO4) batteries. Precision chargers feature battery-type selection by the bank, which now includes charge curves specially formulated for the high demands of lithium batteries, and can even wake these battery types from standby.
