Make the most of your batteries with the ChargeMaster, plugging in and charging anywhere in the world. Mastervolt’s ChargeMaster guarantees fast and complete charging of your batteries no matter where you are. The ChargeMaster can charge multiple battery banks simultaneously thanks to its combined functionality. Moreover, all ChargeMasters can be easily connected to a MasterBus network with only one cable and one connection (not available on ChargeMaster 12/10 and ChargeMaster 12/15-2). You also have the option of central, local or remote monitoring, configuration and control of your system. The ChargeMaster is available in various models to guarantee you the ideal battery charger for any situation and demand.

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.

Metal-on-metal fitting gives a firm connection, and prevents corrosion or overheating of contact surfaces.

The ChargeMaster series has three equal charge outputs. Those of the smaller ChargeMaster models are pre-installed with two metres 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.

Some of the brightest yellowish green tent lights I've ever had
Color: Amber Spot Beam (ZD000706)
I put these on my 2022 Subaru outback the bottom middle section of the bumper in the front spread apart about 2 ft they are very bright they illuminate any reflective surface for at least a mile and a half to 2 mi on the interstate people just move right out of the way when you're behind them because they are so bright five stars very easy to install a top shelf

Well worth the money
Color: Amber Led Offroad Light
Got these mounted on the A-pillars on my XJ. The mounts are sturdy and fairly easy to adjust. The housings are built well. Wiring is 4 out of 5; battery connection is only a foot from the relay so I had to extend the + and - about 3ft in order to mount the relay in a good spot. Plugs seem nice but trying to run/hide the wires for the lights is difficult due to the size of the plugs. Lights are bright with excellent reach and even spread. Lens are crystal clear. We'll see how they hold up against dirt, grime, and water. Side note, the spot beam is exactly that and is not even remotely safe for on-coming traffic if it's pointed forward. I ran these off-road and they were superb and exactly what I was looking for. Well worth the price.

Not bad for money. But the spot lens is def a narrow spot
Color: 4.5inch Spot Light, Color: 4.5inch Spot Light
I did a direct comparison to BD squadron pro with spot lens. Pic one is 1 squadron spot lens, pic two is 1 auxbeam 4.5 Not a pair. Only one light each. Then the video is 2 squadron pro one with spot lenses the other with combo lens. Then both auxbeam 4.5. I wouldn’t buy the spot lens unless you have other lights or just trying to light a narrow beam a long ways. The fill light is not good. I say the brackets and the finish is on par with BD, not as deep as the XL80 but similar in size. The BD XL pro is def brighter with better fill even with spot lenses. I would say 4 of these would match the XL Pro at half the money if you have the space for four of them. But even 4 don’t match the XL80’s. But for 160 bucks it’s a good solid light.

Great quality, and very bright.
Color: 4inch Spot Light, Color: 4inch Spot Light
I installed 4 of these pod lights in the front bumper of my 2009 f150 (2 spot beam, and 2 combo beam), and I am very pleased with the overall build quality, and brightness of these pod lights. Installing them is fairly straight forward once you have them mounted where you want them, and they look great! I highly recommend these lights if you are looking to upgrade the lighting on your vehicle! The video I have attached is with the amber lens, and the picture with the lights on is without the lens. I prefer to keep the lenses on most of the time since it does add a layer of protection from the sun, and bugs/rocks while driving. I also do prefer the amber color for driving at night compared to the white.
