Charging Lithium Ion batteries

Although Lithium Ion batteries are increasingly popular, there can be a lack of clarity when it comes to the charging process. This is not a problem with Mastervolt as the Mastervolt battery chargers communicate directly with the Lithium Ion battery via the integrated MasterBus (or have been adapted to the required charging voltages).

MasterBus compatible

Mass battery chargers can be easily connected to a MasterBus network with only one cable and one connection. You can also choose central, local or remote monitoring, configuration and control of your system.

Made tough by smart design

The certified Mass battery chargers are very strong, designed to withstand heavy vibrations and shocks. Their premium quality components meet the highest possible specifications, while the smart and extra robust mounting adds to the professional end result.

Good Product
Color: White, Size: 15.7 Inches
Well designed and sturdy. Though not real wood I think they will last. It took me an hour to install the first shelf. That was all on me. I was slow measuring and placing the shelf bracket. I kept dropping the level and doing other crazy things. But the second and third shelves were easy after I learned what I was doing. Even though the screws, etc were provided I used Easy Anchor drywall anchors rated at 50 pounds. Just drill it in the sheet rock then screw the screw through the hole in the bracket until it clicks, (you have to listen). That means the ends of the plastic anchor flips out like a toggle bolt. Continue tightening the screw and that is it. Think I read somewhere that the board wobbles. These were tight as could be and no wobble. I did learn to only "tighten" just one end of the bracket sort of snug and let it hang. Then raise it to level and mark the other holes with a pencil. Don't put the other screws in until you are sure you can see the plastic anchors' holes though the bracket. Then place and tighten all the screws. The only negative I saw was that they could have sent the same or similar anchors that I have. But they didn't call me. Guess they didn't have my number.

Easy to Install and Looks Great
Color: White, Size: 15.7 Inches
These floating shelves are a great addition to my daughter room space! They were very easy to install, and the instructions were clear and straightforward. The material feels solid and durable. I also really appreciated that the package included all the necessary hardware and materials, which made the setup even more convenient. They look great on the wall and serve their purpose perfectly. Highly recommend!

Quality Assurance Lacking
Color: White, Size: 15.7 Inches
The first set I ordered was great; super easy to install, no issues. The second set I ordered the holes on the bottom of the shelves did not match up with the holes on the bar that secures the shelves to the wall so it was impossible to attach the shelves correctly. I'm still trying to figure out a solution. TO SUMMARIZE: First set perfect; second set unusable

Worth it if you're a figure/doll collector!
Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch, Color: A. Black Board & Black Brackets, Number Of Shelves: 4, Size: 16-inch
I ordered these shelves to display my figures and dolls, and I love the way they look! I ordered 2 sets of the 4 pack in black with black hardware. After looking at reviews, I took the jump and bought them and don't regret it! TL;DR: Listing is accurate, don't use the paper measurement thingy, quality is what you'd expect for the price, doesn't come pre-drilled, easy enough to put together, over all worth it if you're looking for smaller, decent quality, decent price shelves especially if you display figures or dolls. 1. Listing: They are accurate to the measurements! They're only 5.5 inches deep, so there isn't much (if at all) any room for layering. They do feel small, but the listing is accurate!! Mine are paired next to each other to create a "longer" shelf. DO NOT use the paper measurement thingy. Another review mentioned it was un-even, and after holding it to mine, yeah, it was off. I'd highly recommend a stud finder, small leveler, and a white gel pen or marker to mark where to drill if you do. 2. Assembling & Mounting: The shelves didn't come with pre-drilled holes for the mounting options because it was easy enough to screw into. I will warn you that the small screws only came with a singular extra, so be careful about losing them in case it's the same for you... I'd highly recommend doing this on a FLAT surface. I stood the shelves on the side that would be flat against the wall and set the brackets against it. I put one screw in on each side (both brackets have 1 screw to hold them where I want) then I laid it on its top and tightened and added the other screw. I may have done more work than needed, but none of mine are leaning forward or backward super far. I used the "load bearing" mount simply because I like the look but if you intend to put books, I would do the "no drop" design and possibly get some other L brackets for more support since books can get heavy. PLAN WHERE YOU WANT THE BRACKETS if you intend on doing the "load bearing" design or adding any more brackets. 4. Quality: I kind of expected the wood to be a bit thicker/more sturdy feeling, but upon realizing they didn't come pre-drilled, it made more sense. THEY CHIP AND SCRATCH EASILY. If you're like me and don't really care as long as you cant see/don't notice it, then this isn't any concern but they may come damaged cause some of our mail couriers aren't the best. If you stick them in the corner like I did, please be careful about it slipping! I accidentally dropped the second one from a 21-inch TV stand after adding brackets, and the corner chipped (yes, I measured). The hardware is standard screw quality, and the brackets could be better. After reading the broken bracket reviews plus the price, I honestly wasn't expecting much, but they aren't too bad! You can always replace them with another one you like! 5. Overall: I'd say these are worth the price and I see why "customers usually keep this item"! They were easy enough to mount, even if you aren't the handiest man out there. I'd definitely recommend these if you're looking to display anime figures or dolls like I do! They're nice for adding vertical space without sticking out of the wall too much! Definitely good for smaller spaces! I'm very happy with this product and will more than likely return to this listing if I want some decent and affordable shelving! Thank you for reading my review, Im usually hesitant to buy online so I hope it helps you decide if you wanna buy these shelves as well! (Also, in case anyone is wondering the layout, the longest shelf will be 1, the middle length will be 2, the shortest length will be 3. It's the last image of the review!)
