ChargeMaster Plus 24/20-3 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 Quality!
Color: Ivory White, Size: 2' x 6' (Sheepskin Shape), Color: Ivory White, Size: 2' x 6' (Sheepskin Shape)
I have owned many sheepskins before and this one is by far the best deal. Cheaper than similar sizes, but not in a bad way! It’s a beautiful creamy white, super plush, and is very long. We keep it on the back of our couch and it gives a very cozy vibe. I haven’t had any issues with it shedding. Word of advice for cat owners: When we first got it, it did have a sheepskin smell but it isn’t a gross smell and it went away within a few days; however, my cat was very attracted to that smell and was “attacking” the sheepskin. We trained her not to do it just by spraying her with water—after a few times of that she stopped going anywhere near it. Now that the smell has dissipated, she isn’t attracted to it anymore but does like to sit on it every once and awhile (I can’t blame her, it’s sooooo soft). I saw someone else say their cat ruined their rug, so I wanted to give our story on how we prevented that and hopes it helps another cat owner. You just have to be alert for the first day, maybe even let it off-gas outside first, then keep a spray bottle nearby and the cat should stop messing with it!

Great little rug!
Color: Ivory White, Size: 2' x 3' (Sheepskin Shape), Color: Ivory White, Size: 2' x 3' (Sheepskin Shape)
This nice little sheepskin rug is the perfect finishing touch to my little reading nook. It’s soft and thick. Follow the enclosed instructions to fluff it up. I was going to order a second one but saw that the price jumped nearly $10 in a week. It’s nice but it’s not worth that amount. I’d buy it on sale though. Five stars.

Great valur
Size: 2' x 3' (Natural), Color: Gray Tipped
Soft and comfortable. Quality leather nsckrd. Genuine sheepskin. No off odors. I'm skinny and not on tailbone. Hoping this helps. The grey tipped is more of a bluish gray. Pretty but not s true gray.

On the fence? This is the sheepskin to get!
Size: 2' x 3' (Natural), Color: Wolf Tipped
I've been reading all the reviews for sheepskins on AMZ and felt this company was the one to go for and WOW did they deliver! The sheepskin came well wrapped but not vacuum packed and is even prettier in person than the pictures. It is super soft, fluffy and dense and mine measured 26" x 40". I absolutely love the wolf tipped colors: ivory, dark grey and a slight brownish hue. There is a slight odor but I don't find it offensive. It stayed put on my leather couch and sitting on it during a Netflix movie was heavenly warm and comfortable. I did not observe any shedding. Will definitely buy another wolf tipped one, once it becomes available as it is worth the money.

Gorgeous 😍
Size: 2' x 6' (Natural), Color: Champagne, Size: 2' x 6' (Natural), Color: Champagne
Absolutely beautiful!!! It is thick and luxurious, super soft and cozy. It’s really high quality and it shows. You can tell it’s natural without the burn test even from its cute little curls. All brushed (your pet brush is perfect 😉) out it looks stunning and fluffy. I got the champagne color and I love it! I don’t see any seams on the double pelt and it is substantial, not at all like it will disintegrate in a few years, but rather will become a much loved family heirloom. Well worth the investment! It is absolutely heavenly to perform yoga on by the fire 😌I love taking my slippers off and feeling the soft fur. I don’t want to get off it lol. I understand all those other customer’s kids and cats 🤣😂🤣
