I’ve whipped up a cheap and dirty LM10-based battery monitor for my own projects to circumvent the issue, and if you’re misappropriating tool battery bricks for your projects, do keep in mind that you’ll want to monitor the battery voltage if you don’t want to end up with deep-discharged and dead battery bricks! From what I know, those powertool bricks do NOT have any kind built in deep-discharge protection! Some manufacturers will give you extra terminals on the battery pack to monitor the voltage of the parallel blocks of 18650s and a thermistor output, some will not even do that, but use a proprietary communication protocol to talk with the tool or charger you plug it in. I’ve worked for a while on a project like this for Milwaukee batteries, and also have had a good number of Ryobi bricks to experiment with and disassemble to harvest the cells from. Posted in hardware Tagged battery power, portable power, ryobi, usb charging Post navigation A future improvement to this project could be making the battery interface a separate piece that can be swapped out instead of having to reprint the entire thing. Which incidentally should make adapting the design to other battery types relatively easy, though editing STLs does pose its own set of unique challenges. But with a pair of calipers and a bit of time in your CAD package of choice, it’s possible to design and build an exact match that works like the real thing. Trying to make an interface for a Ryobi battery, without sacrificing a tool as a donor anyway, would be maddeningly difficult with traditional at-home manufacturing methods. There’s also dual 2.4 USB “A” ports and a Quick Charge 3.0 compatible USB-C port for charging your mobile gadgets.Īs an aside, this project is an excellent example of how powerful 3D printing can be when building your own hardware. From there he’s got a standard “cigarette lighter” automotive power connector which offers compatibility with a wide range of mobile devices such as small inverters or mobile radios. Ryobi standardized on an 18 V battery a while back, so is using a 10 A DC-DC buck converter to step that down to a more generally useful 12 V. With support for multiple charging standards and even an integrated work light, this device would be perfect to have around for power outages or to take with you on a camping trip. Looking to find alternative uses for his growing collection of Ryobi batteries, has come up with a portable power station design that lets him put all that stored energy to use. But if you’re just doing the occasional DIY project, those batteries are probably going to sit unused more often than not. If you’re a professional contractor, having a fleet of batteries you can swap out during the day’s work is a necessity. ![]() This kit includes the RYi150CBT 150 Watt 18V Battery Inverter and charger, PBP006 18V 2Ah Lithium-ion Battery, Wall Plug, USB Charging Cable, and Operator’s Manuals.Anyone with a few cordless tools has probably amassed quite a collection of batteries for them. The 150 watt power source and the included battery are backed by a 3-year manufacturer’s warranty. Best of all, it’s part of the RYOBI ONE+ system - Any 18V ONE+ battery works with any 18V ONE+ product. This power source and charger features (2) USB-A Fast Charge Ports, (1) USB-C Input/Output Port, & (1) 120-Volt AC Outlet. You can also illuminate your area using the on-board LED task light. It’s ideal for situations like remote recreational use, travel, remote jobsites, power outages (for powering small electronics), charging on the go, or any time you need reliable power remotely. ![]() You can charge your phone more than 3 times with the included 18V ONE+ 2Ah lithium battery. Power or charge multiple small electronic devices such as phones, tablets, laptops, fans, and lights with up to 150 watts of portable power. Utilizing the unit’s USB-C port, you can charge an 18V ONE+ battery at home with a USB wall adapter, in the car with a 12V USB car adapter, or even outside with a USB-C compatible solar panel. This power source also doubles as an 18V ONE+ battery charger, and charges a 1.5Ah battery in as little as one hour. Expand your RYOBI ONE+ System with the 150 Watt 18V Battery Power Source and Charger kit. ![]()
