Dewalt 20v max upgrade spacer 5 cell to 10 cell

thingiverse

The toolkits with 2x 1.3Ah or 1.5Ah packs are cheap and plentiful, but those packs have limited runtime and power. I wanted to at least double the capacity of my battery packs. This conversion enables me to upgrade the DCB201 or DCB207 from 5 cells to a 10 cell pack. The modification requires four M3 x30mm screws; I used silver ones I had on hand, but you can use black for a sleeker appearance. To create a 2.6Ah and a 3Ah pack, I removed the cells from two 1.3Ah packs and two 1.5Ah packs and spot welded them together. Additionally, I purchased 20 raw Samsung INR18650-25R cells and spot welded them to create a pair of 5Ah packs. This upgrade gives me four fully functional packs with much more capacity. The conversion should also work on the 2Ah 5 cell packs, but I don't have one available for disassembly.
