Venting the Chuck

[Scottes]

I've been doing some comparisons of all my big-battery PVs, and one thing I've noticed is how many have venting holes in case of battery issues. It seems that only two PVs have venting holes - the Silver Bullet and the Super-T. (At least out of all the ones I have...)

Has anyone considered the idea of drilling the Chuck to allow venting?

My thought was to drill a hole in the end cap, right through the center of the spring. I also plan on plugging this with some soft plastic to keep dirt out, but in a way that will release easily to prevent/reduce an issues should a battery have a major catastrophe.


Any ideas or thoughts? Especially from Jeff?

No need for a vent hole. Remove the end cap, and wrap your lips around the end of the chuck and blow.(yes I know it sounds bad...) There is plenty of air movement. More so than if it was perfectly air tight and you drilled a small hole in the end cap.

Remove the end cap, and wrap your lips around the end of the chuck and blow.

I did that, and on my Chuck the air movement is about equivalent to an 801. That is, there's very little air movement. Not enough to make me happy.

Are you using unprotected batteries?

I've thought about it, but I haven't tried yet and more than likely I won't. I don't really see much of a need for me since I use protected batteries, and have been experimenting with LiFePo4's, both of which should never vent with flame, even when shorted. I can see where the unprotected CR123s could really be an issue though.

Fact: The most-recently purchased mod produces the most vapor.

Nice sig BTW

Good gawd no. Besides, there's still a chance that protected batteries can vent.

Doesn't really matter though. For the amount of time I'd spend drilling a hole it's worth covering myself for a billion-to-one shot.

Cool, have at it then. Dead center of the end cap would work then. Make sure to use a center punch and a drill press so the bit does not walk on you, and scratch the powder coat. Obviously, remember to take the spring out too.

I get more air blowing thru my Chucks than any other mod I have...Hmm... The silver bullet was my biggest worry bc i get barely any air from blowing thru it but its so darn thick, and since its aircraft grade, I just dont think it will blow it to schrapnel. Just my .02 tho. I also use protected batts...well, for the most part

The button will push up if a bad event should happen on the Silver Bullet. With the Chuck tho it's bolted on....

I hope I'm not the one that finds out what happens on the chuck.

Me either!!! Im just sayin if I blow thru the bottom w/cap off I get a ton of air... Im def not scared of the SB bc of its thickness. On another note tho, I DO trust my Chuck

One other thing to consider though. I don't know exactly how explosive a li-ion batt can be, but I've heard it can be pretty strong. By directing the force straight out the end cap, in the event your battery does vent w/ flame, you have effectively turned your Chuck into a rocket aimed down your throat.

If you were to put three holes 120 degrees apart in the tube or even around the end cap instead of in the end, you would eliminate any possible rocket effect. You might singe your hand a bit, but you wouldn't choke on your Chuck (that sounds so wrong, but hey...).
