Product Description
Stop Juggling Chargers for Every Battery On Board
If your boat, pontoon, or tow rig runs on more than one battery, you already know the hassle: swapping chargers, forgetting one bank, or babysitting a trickle charger all weekend. The NOCO GENPRO10X4 solves that by charging four separate 12-volt batteries at once, each with its own dedicated 10-amp bank. Plug it in and walk away.
Handles Whatever Chemistry You're Running
Not every battery on your boat is the same, and this charger knows it. Each bank can be set independently to match the battery connected to it:
- 12V mode for standard flooded, gel, and maintenance-free batteries
- 12V AGM mode for sealed AGM batteries
- 12V Lithium mode for LiFePO4 batteries with a built-in BMS
- 12V Repair mode to recover old, idle, or stratified batteries
That means your starter battery, trolling motor bank, and lithium house battery can all charge safely, at the same time, off the same unit.
Built to Live on the Water, Not Just Near It
This isn't a garage charger you're borrowing for the marina. The GENPRO10X4 is fully sealed to an IP68 rating, so it's designed to handle rain, spray, and even full submersion without missing a beat. NOCO backs that up with extended underwater life-cycle testing, not just a spec sheet claim.
Installation That Doesn't Fight You
A simplified mounting system lets you install the charger in any orientation, including upside-down in a tight compartment, with an anti-vibration backing that isolates it from engine shock and rough water. Once it's mounted, an integrated thermal sensor automatically adjusts the charge rate for outdoor temperature swings, so it won't overcharge in the summer heat or undercharge on a cold morning at the dock.
Recovers Batteries Other Chargers Give Up On
Left a battery sitting too long? The GENPRO10X4 can detect and begin charging batteries as low as 1 volt, and its Force Mode lets you manually kickstart batteries that have dropped all the way to zero. Combined with automatic sulfation and stratification detection, it's built to bring tired batteries back, not just maintain healthy ones.
Ready to stop babysitting your battery bank? Add the NOCO GENPRO10X4 to your cart and get every battery on board charged, maintained, and ready to go — automatically.
Tech Tip: Using A Multi-Bank Charger
Each bank of this charger is 10 amps. Combined, this is an output of 40 amps (4 banks of 10 amps each). This is commonly used in two ways:
- Connect each bank to separate battery systems, charging both by 10 amps each.
- Connect both amps to the same battery system, charging it by 40 amps total.
Frequently Asked Questions
Can the GENPRO10X4 charge lithium (LiFePO4) batteries?
A: Yes. It includes a dedicated 12V Lithium mode designed for LiFePO4 batteries with an onboard BMS, so you don't need a separate lithium-specific charger.
Can I use this to charge a single 24V, 36V, or 48V battery?
A: No. Each of the four banks only outputs 12V. You can combine two banks to maintain a 24V bank of 12V batteries, or all four for a 36V or 48V bank, but it won't charge one high-voltage battery directly.
Do I need to remove the charger before taking my boat out on the water?
A: No. Its IP68 rating means it's fully sealed and safe to leave mounted and connected in wet, splashing, or even fully submerged conditions.
Can I mount it upside-down or in a tight compartment?
A: Yes. The simplified mounting system and anti-vibration backing let you install it in any orientation, including upside-down.
Where is the NOCO GENPRO10X4 made?
A: NOCO engineers the GENPRO10X4 in the USA and backs it with a 3-year limited warranty for extra peace of mind.

Customer Reviews
This is hands down the best on the market. I like the fact that you have one charger that can do it all. This 4 bank charges 3 lithium batteries and my cranking battery. As a Charter Guide the fast charge time is also beneficial. Awesome product!
Bought this for a 48 Volt golf cart... Has the new AGM batteries and this thing is fast & waterproof... Great product.. We use these a lot in the marine business and they work great.
