i ment should i drill a hole in the chasis of the flashlight i am moding so if a bat does vent the toxic gas can escape from the unit instead of building up pressure inside...
but i guess its best to do it just from yer firecracker comment
and thanks fer the help!
Oh, okay. Yeah, I don't see why that would hurt. To be honest, if for some reason, the battery expels gas, you'll definitely know before this happens because there will be extreme heat emitting from the battery.
Also, not so sure how effective it would be drilling a small hole for the purpose of the mentioned. Unless your mod is rock solidly made, force will travel through less resistance and it would still be the area where your connector was fashioned into. So, even if you drilled a small hole, the diameter of a small hole, say the size of the hole in your atty. This wouldn't be sufficient for built up pressure to travel out of, IF this was occurring rapidly.
I just don't see this happening anyway, vent or no vent. My flashlight mod, one in particular is completely water proof. No vent, no hole, no nothing. The battery is not engaged long enough for any built up heat to occur. We momentarily consume energy in the vaping realm.
But, if you have a short, you'll have a problem. Make sure you protect all wires and solder joints.
Anyway, still better safe than sorry I supose.
