I recently just started building my second electric longboard. I wanted to build a 18650 battery but didn’t want to solder every cell, and didn’t want to spend money on a welder. I saw that vruzend.com has their diy battery pack plastic pieces, but I thought those were too bulky and for a pack with more then 30 cells would be a little more then I wanted to spend. So I thought why not 3d print holders and make my own case that I could just slide the batteries into? For this build I ended up deciding that I just want to buy a sled pack from someone for simplicity.
I know a lot of people don’t want to weld or solder their cells, and I thought some people might be interested in purchasing a pre-built battery sled. So I am currently considering 3d printing small packs and for people who are interested, I would assemble the packs into small or large battery packs and solder wires to the slots that have nickel strip (or some other form of connections) as connectors. Since I would be designing and 3d printing the holders, I could make any sized sled for custom builds. All you would have to do is slide the battery in and connect a bms.
Now I am still designing how the sled will function and how it would hold the batterys, but I wanted to make this post and ask if there are enough people out there with an interest. Each pack would be roughly $30-$40 depending on the size of the pack you would like. So let me know if anyone would have an interest in purchasing one or if you have any other ideas.
