Fatshark Battery Case for 18650 Batteries

This is a quick model I sketched up to enclose a simple 2 cell 18650 battery pack for my fatsharks. 18650 Lithium Ion batteries are extremely common and if you have spare rechargeable gear lying around - chances are you can harvest some cells to repurpose. Official Fatshark batteries retail for about $24 and have some serious issues with quality control - many reports of failed cells something I experience myself. I was able to scavenge all the parts so all this cost me was my time.

Fatshark goggles take a 5.5mm x 2.1mm barrel jack. To keep the profiles ergonomic, search ebay for right angle adapters. To make the balance charge adapter - you need JST - XH pigtails or headers and crimps and some 26awg silicone wire. Pigtails are quite common on ebay just search for 2s balance connectors.
