Joined the forum just to share. So there are aftermarket adapters that allow use for Makita, DeWalt, and Milwaukee batteries to be used on Ryobi tools. Here in Dallas there is a neat place, like a 24 hr fitness, except it’s a workshop. $500 a year and you have access to lathes, 3d printers, plasma torches, etc. Been meaning to go and join to print parts for PC pancakes. Don’t want to buy the $50 manifold assembly, especially for a $3 plastic part and 50¢ o-ring (Work on tools for a living). What I am curious about, does the firmware of the battery track anomalies in usage? I know the Ryobi 40v batteries will lock themselves out when you repair them(the ground gets disconnected via firmware if you break the circuit. Somewhere on that dang pcb is some voodoo that kills the whole thing if it hits 0 volts before negative out, so if you change a capacitor, rectifier, or if it discharges below 26v and is left longer than a month, it self discharges to 0 and will never work again.) Long story short, anyone information on the t1’s 2’s 3’s would be appreciated. Also, most batteries are stupid easy to fix. Exception for the 40v, and Ridgid. I want to play with making an adapter for use of cheap batteries to expensive tools. I have a ton of Ryobi 18v batteries I have repaired as well as BD 20v and 18v batteries on deck.
