What's in the box:
- SS3HF Charger
- 6' AC power cord
- 6' DC charge cables
- (4) mounting screws
- Three Independent 10A Banks: Each bank delivers a full, unshared 10 amps — so a weaker battery in one bank won't slow down the charge on the others.
- Per-Bank Selectable Algorithms: Configure each bank separately for Flooded (FLA), AGM, or Lithium (LiFePO4) to match whatever battery chemistry is connected to it.
- Ideal for 36V Trolling Motor Systems: Designed for boats running three 12V batteries in series, with independent charging to bring each one up to full charge properly and evenly.
- IP67-Rated Marine Construction: Dustproof and submersion-resistant, with certifications for both fresh and saltwater use and compliance with ISO 8846 marine standards.
- Coast Guard Certified & Reverse Polarity Protected: Ignition protection to US Coast Guard standard 33 CFR 183.410, plus built-in reverse polarity protection for worry-free permanent installation.
- Float Maintenance Mode: Automatically holds all three banks at peak charge after the cycle completes — no overcharging, no manual intervention needed between outings.
Product Description
Three Batteries. One Charger. Every Bank Done Right.
If your boat runs a 36V trolling motor, you already know the challenge: three batteries to charge, potentially at different states of charge, different ages, or even different chemistries. A single-output charger can't handle that properly. The Dual Pro Sportsman HF SS3HF can — with three fully independent 10-amp banks delivering 30 amps of total output, each one working on its own without pulling from the others.
That independence matters more than most people realize. When banks share amperage, the weakest battery slows down the entire charge cycle. With the SS3HF, each bank runs its own multi-stage charging sequence from start to float, so every battery gets exactly what it needs regardless of what the others are doing.
Match the Charger to Your Batteries, Not the Other Way Around
Each bank can be configured separately to match the battery it's connected to. Running a mix of battery types across your system? Set each bank accordingly. Available charging algorithms include:
- Flooded Lead-Acid (FLA)
- AGM
- Lithium (LiFePO4)
This makes the SS3HF one of the most flexible options available for anglers who've mixed battery types over time or recently upgraded one bank to lithium. Always verify lithium battery compatibility with Pro Charging Systems before use.
Built to Handle Whatever the Water Throws at It
The SS3HF carries an IP67 rating — fully sealed against dust and protected against short-term submersion. It's certified for use in both freshwater and saltwater environments, meets ISO 8846 marine standards, and holds US Coast Guard ignition protection certification (33 CFR 183.410). Reverse polarity protection keeps the unit and your batteries safe if connections are made incorrectly.
Output current doesn't taper off as batteries charge, delivering the fastest charge time in its class from start to finish. Once complete, Float Maintenance Mode holds all three banks at peak charge automatically, with no risk of overcharging while the boat sits at the dock.
Practical Size, Permanent Fit
The rugged polymer housing measures 3.25" x 8.0" x 11.25" and weighs 9.2 lbs — manageable for a permanent install even in tighter onboard compartments. Everything needed is included in the box: a 6' AC power cord, 6' DC charge cables, and four mounting screws. A 3-year warranty covers the whole unit.
The SS3HF is also compatible with Dual Pro's optional Battery Gauge and Battery Optimization System (B.O.S.) accessories, both of which pair with the PROView Link app (Apple App Store / Google Play Store) for real-time battery monitoring from your phone or tablet.
Frequently Asked Questions
What kind of boat setup is the SS3HF designed for?
A: The SS3HF is a natural fit for anglers and boaters running three-battery setups — most commonly those with a 36V trolling motor using three 12V batteries in series, or boats with a dedicated starting battery and two separate trolling or accessory batteries. If you need three batteries charged properly overnight, this is built for that job.
How is independent charging different from a standard multi-bank charger?
A: On chargers that share amperage, the total output is divided between banks — meaning a discharged or aging battery can pull resources away from the others and drag out the whole charge. With the SS3HF, each bank runs its own dedicated 10-amp charge cycle from start to float, independent of what's happening on the other two. Every battery gets what it actually needs.
Can each bank be set to a different battery type?
A: Yes. Each bank is configured independently, so you can mix and match Flooded, AGM, and Lithium settings across the three banks to match your exact setup. If you're using lithium batteries, verify compatibility with Pro Charging Systems before use.
What comes in the box?
A: The SS3HF includes a 6' AC power cord, 6' DC charge cables, and four mounting screws — everything needed for a straightforward permanent installation.
