![]() This can be fooled with an adapter from an old battery which could in turn be attached to a homegrown mount. The third tab is both a thermistor and a comms* tab. Here is the explanation and solution I’ve come up with. Posted in Tool Hacks Tagged 18650, adapter, charger, controller, cordless, dewalt, Li-ion, ryobi Post navigation After all, printing an adapter should be easier than whipping up a cordless battery pack de novo. While took a somewhat brute-force approach here, we imagine 3D-printed parts might make for a more elegant solution and offer other brand permutations. The video below shows the process and the results - Ryobi tools happily clicking away on DeWalt batteries. That meant simply transplanting the PCB from the adapter to the Ryobi battery shell would be enough. Luckily, the donor DeWalt line has that circuitry in the adapter, while Ryobi puts it in the battery. The tricky part came from dealing with the battery control electronics. Mechanically, this was pretty easy - a dead Ryobi pack from the recycling bin at Home Depot was stripped down for its case, which was glued to a Dewalt 20-v to 18-v battery adapter. ’s solution is a pure hack, as in physically hacking battery packs and forcing them to work and play well together. Luckily, we live in the future, so there’s a third way - building a cross-brand battery adapter that lets him power Ryobi tools with his DeWalt batteries. Could he stay true to his brand and stick with his huge stock of yellow tools and batteries, or would he succumb to temptation and add another set of batteries and chargers so he could have access to a few specialty lime green tools? Yes, batteries are my sickness (one of many)Even though he’s a faithful DeWalt cordless tool guy, admits to a wandering eye in the tool aisle, looking at the Ryobi offerings with impure thoughts. ![]() I constantly use the battery operated radios and very often need lights for a variety of odd jobs that won't even involve power tools. I also buy radios and flashlights for any system I have so that batteries don't sit months without use on systems with limited or specialized tools I use infrequently. Always use the first battery and never leave a battery in a tool unless it is a tool that gets lots of use, like an impact drill. Battery needs a charge.to the charger and then goes to the back of the line on a shelf, and slide them up one slot. I am pretty meticulous (anal) about rotating batteries. I have bunch of M12 batteries from 2010/2011. Not sure why those died while some others are still going strong beyond 10 years. I have a little over 20 of the LXT 18v and have had 2 die, both were in the 10 year range. My Makita LXT batteries, I have my earliest going back to 2008, 13 years. Every battery I have I always grab a Sharpie or those paint pens and mark month/year on each so I know how long I have had them. I have the Makita LXT 18v system, as well as other systems. Seems logical to just get something that will all use the same battery and toss the Dewalts Does anybody have a Makita hammer or a 3/8 right angle?Ĭhecked to see if CPO had any good deals - not currently. It looks (although I'm not sure) like Makita still uses the same battery design - mine are BL1815. It seem silly to spend another $129 for the 12v batteries and over $100 for the 18v's Nice kit and the batteries still work for my needs. they did not hold up.Īt least 5+ years ago - I picked up a Makita kit to keep at another house (case, 1/2 drill and impact driver combo w/ three 1.5 Ah Lithium). Rarely use the right angle (once or twice a year) - for that reason a couple of battery cycles back I went aftermarket for the 12v batteries. I'm not a heavy tool user - but, when you need it you need it. ![]() Seems to come around every 3.5 years or so.īoth batteries for my trusty old DW998 1/2" hammer drill using the 18v XRP and the equally old right angle 3/8 DW965 using the 12v XRP are dead or close to it.
