Product Details

The Mastervolt ChargeMaster 12/25-3 is a professional-grade 3-bank battery charger designed for 12-volt battery systems in marine, RV, and automotive applications. This intelligent charging system delivers 25 amps of total charging current distributed across three independent banks, allowing you to charge multiple batteries simultaneously with precision and safety.

Key Features:

  • Three independent charging banks for multi-battery systems
  • 25 amp total charging capacity with intelligent distribution
  • 3-stage automatic charging (bulk, absorption, float) for optimal battery health
  • Universal input voltage: 120/230V AC for worldwide compatibility
  • LED display for easy monitoring of charging status
  • Compact dimensions: 9.2"H x 5.2"W x 2.4"D for flexible installation
  • Includes 2-meter AC power cable
  • Screw-mount terminal connections for secure battery hookup
  • Microprocessor-controlled for safe, fully automatic operation

The ChargeMaster's 3-step charging algorithm maximizes battery performance and lifespan by automatically adjusting charge parameters based on battery condition. The system transitions from bulk charging to absorption mode, then maintains batteries at optimal float voltage for long-term storage readiness. Ideal for boats, RVs, service vehicles, and any application requiring reliable multi-bank charging capability.

You had some issues when I tried to check out.

Wish shipping was cheaper

What I needed and in stock So far so good ;-)

Easy ordering. Lightning fast delivery!

I ordered the HuskyLiners 98891 Floor Liners for my 2012 Hyundai Elantra on 5/29, received them 5/31. Order #15417. Apparently they have warehouses all over the country to ensure quick delivery. They had the best price on the net. Item arrived in perfect condition. <br><br>Their website needs a little work because I found the item thru Google and not directly from their website. You also can't edit your cart unless you register first which was annoying. Items could use product descriptions - you have to get info from the manufacturer's site. The real-time inventory was a plus.<br><br>Deducted a star because their website needs work.

Very easy shopping process

Needed a part and found it on their site for the lowest price on the internet, and they shipped it quickly!

W]wwwwww

Great product! Don't even think about another battery hold down - this one is strong, light and has the good looks to boot. Saved over $30 on it too.

good shopping experience

Good
