Bored at the drone lab.

Rained all morning at work so did some Dividing by zero at Falkor Aerials.

I made this thing with some spare parts and was immediately terrified to keep it in the same room as our flight batts.

What am I looking at??

I dare you.

Always remember the brave children who died defending your right to bear arms. Freedom is not free.

>What am I looking at?

Something to blow up batteries. (or at best trip their protection.)

I guess you got some lipos to dispose of and a salt water bath is too boring?

Yep. Just making sure the breaker trips on our 3 pound lipos.

My evil new tool is in a sealed bag in a separate room after I left. Nobody has access to the lab but knowledgeable adults and I didn't even tell them where I put the device. I now have an intimate understanding of the paraphrase "Idle hands are the devil's handiwork".

I dare you.

After a year working with high power lipos I am genuinely nervous just holding this thing it or it being in my pocket. We have a dedicated blast wall and much more efficient ways of shorting our worn out big batteries. This thing you would have to plug in by hand. That would weld a thick rubber glove to a finger bone and remove the front of a persons face.

Run away screaming!

No way! I coincidentally just received my ISA jacket. Waterproof, fireproof, radiation proof, and puncture proof with type IV armor.

major battery fire on the DSC
It was me!!!

But in all seriousness, sad day for the challenger.

We actually did this with a contactor (think big high-current relay) and a single 30 Ah 15C LiPo cell from our hybrid racecar. It was very underwhelming: it started off at 800 amps, it heat up itself and the 0AWG wires, then inflated, de-laminating the layers, then the current dropped off quickly to 0. A bit of smoke but that's it.

What was a lot more impressive was poking one with a nail, we were glad that we did it in a blast shield. I highly recommend you do this at least once, I learned to respect these batteries and be more careful around them. Use a 5m long stick with a nail or screw at the end.

Whoops, somehow missed that
