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.

Great insurance!
It worked wonders for me! I sent back my vacuum after a year of using it because a broken spinning wheel and they repaired it. Then, three weeks before the insurance cover expired, a lightning storm occurred in my area and my vacuum didn’t work anymore, they said they couldn’t fix it and they sent me a full refund. Of course I’ll recommend Asurion insurance!

Do not purchase. BBB will help
Don’t waste you money on this if you’re purchasing a vacuum costing you 6-700.00 or more. We have completed the claims process twice so far, called more time than I like to admit. Bought extremely large boxes and packaging and tape. Drove to ups, waited for ups only to not have our unit repaired. This last claim which was 24 hrs after we received the “fixed” item back was in the companies possession for just two hours when we were sent a msg stating they could not repeat the issues and it was on it’s was back AGAIN. So without a working vacuum for weeks it is now headed back with the same issues. The customer service line assure us they would not let it ship out and would instead keep it and a supervisor would check it and found but 10 minutes after my call I received a tracking number. Save yourself the headache and insure through someone else. Vac sounds like a power saw with rocks in it and won’t clean. Company see that as normal. Told many lies and still repair/.refund

Delivered on What They Promised
Bought an iRobot Roomba i4+ about 1 1/2 years ago and saw this as an option for a protection plan. I was skeptical, as I know that plans similar to this one can be filled with contractual Loop holes that do not benefit the buyer. HOWEVER, this one is legitimate and came through for me when my vacuum was essentially falling apart…as I was reimbursed the full amount that I paid for it. I just purchased another iRobot, along with the same protection plan……so, from my experience, I highly recommend it.

Quick, Simple, and Stand Behind what they sell.
Filed a claim and immediately received a response with instructions. Once I mailed the defective product, with the provided mailing label, I received my refund. Quick, simple, and honest.
