Hey all, I’ve been into the 18650 second life power wall scene for a year or so and ended up with a ton of tool cell batteries. I figured out how to fix many of them, especially the Ryobi 40V packs. During this time I also rebuilt some Headway packs to power my golf cart and got comfortable with spot welding, BMS wiring, IR & capacity testing and lithium charging/discharging safety. So I decided to build a little e-bike to use these cells! I’ve recently transitioned to my DIY pack instead of using those Ryobi packs and adaptors wired into a fuse block.
I had an old (2006ish) steel hard tail Diamondback Outlook. I’ve never done more bike maintenance than change tires, but away I went with a $200 kit off Amazon. https://www.amazon.com/Electric-Conversion-Brushless-Controller-Freewheel/dp/B097YXPFV7 I found a cheap rack at a bike store; it didn’t really fit but some leftover hardware from a TV mount and it was ready. I’ve used this bike to commute 4-7 miles on bike paths and lanes pre conversion, but my newer location would require 16 miles including some heavy traffic roads with no shoulder or path. Here is where I’m at so far, with under $250 spent total….
