Fat Shark 18650 Battery Pack by Zaadams095

Last crawled date: 3 years ago

I got tired of my Fat Shark Lipo and wanted to do the 18650 battery mod, but I was not comfortable soldering directly onto the battery because i really didn't want to have a battery blow up in my face. Thus this was born. This case is designed to have battery contacts soldered on so no soldering iron ever touches the batteries. There is a channel down the center for the second cell balance wire to go in. After all wires are soldered and work you can then fill the cable tracks with hot glue to seal everything in. The nice part about this case is that if you have a separate 18650 battery charger, you only need one case and when the batteries die you can just swap them out. There are many ways to mount the lid, my way is to drill two small holes on opposite corners and the use heat set nuts on the bottom part then secure the lid with small bolts.
*If there is interest, I will design one that has room for a battery level indicator
