ChargeMaster Plus 12/50-3 Battery Charger

Make the most of your batteries with the ChargeMaster series, plugging in and charging anywhere in the world. Mastervolt’s ChargeMaster guarantees fast and complete charging of your batteries no matter where you are. Thanks to Mastervolt’s innovative 3-step+ charging process, batteries also perform better and last longer.

All ChargeMasters can be easily connected to a MasterBus network with only one cable and one connection (with the exception of the ChargeMaster 12/10, ChargeMaster 12/15-2, and ChargeMaster 24/6). What’s more, you have the option for central, local, or remote monitoring, configuration, and control of your system.

Clear Display

A clearly lit display on the ChargeMaster provides all essential information: charge current, charge voltage, charge phase, and battery content measurement and/or battery condition measurement as a percentage of available Ah capacity. The display also provides an indication of MasterBus communication. Three buttons adjacent to the read-out panel allow for easy operating of the entire system. 

The ChargeMaster is available in various models to guarantee you the ideal battery charger for any situation and demand.

Features:

  • For recreational and semi-professional use.
  • Suitable for any type of battery, including Lithium-Ion batteries.
  • 3-Step+ charging technology for fast and complete charging also charges depleted batteries.
  • Memory function prevents overcharging in case of unreliable mains.
  • Safe and complete charging due to standard safety features.
  • Charging capacity up to 1000 Ah battery banks.
  • Easy to connect and quick to install.
  • Can charge multiple battery banks simultaneously.
  • Built-in system functionality (MasterBus) in combination with other Mastervolt products.
  • Clear control panel (with the exception of the ChargeMaster 12/10, ChargeMaster 12/15-2, and ChargeMaster 24/6).
  • Supplies your system without a battery.

Charging your batteries with every voltage

The Mastervolt ChargeMaster supplies a maximum capacity wherever you are via auto-ranging. Auto-ranging ensures perfect fully automatic operation anywhere in the world, regardless of the available mains voltage (90-265 V AC, 50 or 60 Hz). The 3-step+ charging technology guarantees fast and complete charging, while the cos phi 1-regulation gets the most out of limited generator capacity.

Robust Connections 

Solid metal-to-metal connectors equipped with strain relief prevent corrosion and overheating.

Charging multiple battery banks

The ChargeMaster series has three equal charge outputs. Those of the smaller ChargeMaster models are pre-installed with two meters of cable for a plug & play solution, while the heavier models have one full output (for example for your service battery) and two outputs of 10 A, ideal for your starter batteries.

DC Power Supply

Even if the batteries are not connected, Mastervolt ChargeMaster battery chargers can provide a constant DC output allowing you to turn on lights or keep the fridge cold.

Well-made & roomy!
Color: Green
This a beautiful, well-made bag! It shipped quickly, and was packed very carefully within its own dust bag. I really love the dark green color & like the dark gradations on the corners. The zipper fabric is a dark brown, but it blends very nicely. There's lots of space, enough for a book!, and the handles/strap feel sturdy. I added a cute frog charm for some sparkle, but the bag is pretty on its own too!

Almost perfect!
Color: Green
I'm going to be traveling for over 30 hours next week. I've had my eye on this bag for a few months and decided that it would be perfect for my bag I keep under the seat in front of me. I take as little onboard as possible. I check everything. This holds my 13" MacBook Air easily along with my makeup bag, regular purse junk with room left for a pile of snacks. It did have a strong odor when I took it out of the box but I've had it about a week and it seems to have disapated. I wish the handles were a little longer so I could throw it over my shoulder, I'm not someone who will use the strap. Straps and handles are just weird to me. There are tons of pockets though! Definitely a good purchase!

Beautiful Large Purse
Color: Light Brown
5 STARS !! Love this purse. I have had expensive name brands and this I has been my favorite. Love the size, the hardware, the long strap, stong handles, the feet on the bottom the color is beautiful. Great quality so far 6 months. Even got sprinkled on in the rain dried no spots. The large is large so if you like large bags it is it. I have always wanted a I guess you would call it a medical bag. As you can tell from this I really love the bag
