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.

Perfect book with a strong research basis presented in an age-appropriate and fun way
Format: Board book
Fantastic, research-based book - I love the clear detailing of specific strategies (not just "use strategies" like other books often have) and it's written at a level that is easy to understand for a variety of ages. It's also pleasant to read as an adult, which you can't say about many didactic books like this. Illustrations are very cute. I can already tell this will be a powerful book in our arsenal!

Most Useful and Applicable Toddler Book I’ve Found
Format: Kindle
Goodwin’s series continues to be one of my favorite parenting tools I’ve found. While my toddler loves the images and messaging, Goodwin’s applicable and usable tip list in the back of her books is the secret sauce that sets her apart. A must for caregivers of young children!

Perfect toddler book for teaching big emotions and calm down techniques in a simple, visual way
Format: Board book, Format: Board book
What I received / first impressions: This is a picture book written for toddlers and young children that walks through what big emotions feel like, where you feel them in your body, and what to do when they show up. It is written in a way that is easy for kids to follow along with a parent and includes practical techniques they can actually use in the moment. What I liked: - Perfectly written for young kids: The language and pacing are just right for toddlers to stay engaged and understand without getting lost. - Teaches body awareness around emotions: I love that it helps children recognize where in their body they feel emotions, which is such a foundational skill for emotional regulation. - Covers a full range of emotions: It addresses big feelings that come from both difficult and happy moments, and acknowledges that emotions show up differently for everyone which is an important and inclusive message. - Interactive and easy to practice at home: This is something you can do together as a family, not just read and set aside. The techniques are simple enough for little ones to actually try. - Parent tips included in the back: The added section for parents on how to integrate the techniques into daily life is a thoughtful bonus that makes this more than just a read-aloud. - Great addition alongside other behavior books: We are fans of the Best Behavior series like Teeth Are Not for Biting and Hands Are Not for Hitting and this fits right in alongside those in both tone and approach. What I didn't like / concerns: Nothing. This book delivered exactly what we needed and then some. Who I think this is best for: - Parents of toddlers and young children looking for a practical, visual tool for emotional regulation - Families who already enjoy behavior and feelings books and want to add to their collection - Anyone looking for a book they can actively use with their child rather than just read to them - Teachers or caregivers working with young children on identifying and managing big emotions Bottom line: This book has genuinely helped us work through big emotions at home in a way our child can understand and participate in. It is visual, approachable, and gives both kids and parents real tools to use together. We are so glad we found it and it has earned a permanent spot in our regular reading rotation. Would I buy again? Yes, and would gift it to other parents of young children without hesitation.
