The first time you switch on your drone is often referred to as the "smoke test".
If all goes well, you have passed it, if not, you will inhale blue magic smoke and replace parts! Compared to standard smoke stoppers, the TBS Smoke Stopper offers much lower triggering and holding currents and a faster reaction time. It also offers a wider range of input voltages.

Properties:
Connector: XT30 & XT60 (input and output)
Input voltage: 1-14S (3 - 60V)
Trip current: 1.0A
Hold current: 0.5A

Note: This is only a backup. Something may still break if the fuse trips. This does not protect against all kinds of damage, but it is still much better than nothing!
