FAT SHARK The FINAL - split 18650 battery case

thingiverse

This case will save your ear! Ditch that flimsy Fatshark battery case and say goodbye to the discomfort it brings! Printed in PETG, PLA is far too fragile - you'll need to get those critical battery contacts like in the picture. Be extremely cautious when soldering the positive terminal wire, as 18650 batteries have a notoriously low positive terminal that's easily damaged if you add too much solder; short-circuiting the battery can potentially cause serious burns! You're also without a battery voltage meter, so exercise caution and don't over-discharge your batteries - or better yet, create your own BMS. I've connected the middle balancer pin to charge my batteries without removing them from the case. The positive terminal is positioned towards the back, while the front side features springs that provide extra space for wiring.
