3s 18650 pack for fpv goggles

thingiverse

I'm done with my SkyZone's constant alarming when its lithium-ion battery is running low and shutting down at around 6.9 volts. 3S works great, you just need to set the power source to 2S or DC-in and keep an eye on the end voltage, which will likely be around 9.5 volts. Mine shows a reading of +0.1 volts under load, so make sure to check yours with a voltmeter before deciding when to turn it off. Note: This is a non-separable pack, meaning you'll have to solder the cells together and use glue to assemble the case. Printing notes: Recommended materials: Grommet - any flexible material Other parts - any hard plastic; I prefer ABS, which acetone can easily bond with Upscale up_cap, cap, bottom_cap by 101% or they won't fit properly on the core part. You can print all three parts at once.
