I’m planning on building a L-ION battery pack in the future as the detailed instructions on this site are so good, and it looks to be a fun project. But… I’m also interested in commercial off the shelf solutions as well. I have a pretty nice collection of Dewalt tools and I was looking at some replacement batteries online and it got me thinking about using these for this project as well. I can buy 8 20V 6Ah batteries for about $400. I was thinking of designing a case that could hold all 8 running half in parallel and the the other half in series. Thus, I would have a 40V, 24Ah setup running a Flipsky 65161 motor, Flipsky 200A, 60V VESC, ducted 3D printed prop. I’ve got a high lift Naish wing that works well at 8-10 mph and am not real interested in going much faster. I also live on a small lake so I don’t need anything more than 20 min ride times.
Has anybody done this yet? What thoughts do you have on this?
Right now, I’m thinking several things. Advantages are: save build time, avoid issues with LIPO batteries. quick disconnect, multi use function (can use in all power tools to include leaf blower, etc.)
Disadvantages: lower voltage, higher weight.
What am I not thinking about? Thanks! -Marc
