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.

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.

Sun Bum kit a saver!!
Style: Mineral
Great little bag full of sunscreen for my grandson. Glad we had it to take it everywhere with us. A little pricey but he needs it so instead of taking bunches of bottles we had this.

Sunscreen is great, I would t recommend the chapstick
Style: Original
Sun Bum is hands down the best sunscreen I’ve ever used. It smells incredible, like a tropical vacation with that perfect coconut scent. It goes on smoothly, doesn’t leave you feeling sticky or greasy, and actually works! As long as I reapply every few hours, I don’t get burned, which is more than I can say for most other sunscreens I’ve tried. The face stick is good, goes on easily, but is a little greasy feeling. I do not like the chapstick, I can’t keep the taste of it out of my mouth and I feel like you have to put it on again and again.

Best smelling lotion on the market, hands down
Size: 8 Fl Oz (Pack of 1)
I am a huge Maui Babe fan. It is, hands down, the best smelling lotion on the market, and I am obsessed with it. It's very smooth and refreshing when I put it on, and it does not leave any sort of sticky residue or greasiness. It's my absolute favorite and I always tell people about it when they comment on how nice I smell :)

The Maui Babe lotion is truly amazing! It smells wonderful and goes on light
Size: 8 Fl Oz (Pack of 1)
First of all, let me start of saying I never write reviews, so I hope that tells you something. I bought this lotion while my husband and I were in Hawai'i on our honeymoon. I have freckles with semi-fair skin, so I tend to burn - then tan. The Maui Babe lotion is truly amazing! It smells wonderful and goes on light. We had a Jeep while visiting Hawai'i for 10 days, so I ended up with a slight case of sun poisoning on my chest. I applied the Maui Babe and Aloe for 2 days, and the sun poisoning was gone. I didn't peal AT ALL!! In addition, I literally kept my tan for at least three weeks after returning from Hawai'i. One of the more interesting things; I have noticed a difference in my skin. I have never been much of a makeup person, as I like the natural look. Mascara is it. I am 35, so age is slowly creeping up. I started using Vitamin C serum a year ago, but didn't notice much of a difference. After two weeks of using the Maui Babe; my face had a glow and looks so healthy. My fine lines seem to be less and my skin looks more alive. The lotion doesn't irritate my skin one bit, nor did it cause me to have any sort of pimples; however, I am blessed to have never had an issue in that department. I don't know if it will do the same for you that it has done for me, but I feel that the natural ingredients in this secret lotion are magic. Sometimes it's the simplest things that do the trick. I have everyone in my family using it. I highly recommend it!!
