i just purchased a therion 75c bf ,and while putting the battery in (which is very difficult to do) ,the negative end of the battery made contact with its proper connecter but was on an angle and it also briefly touched the squonk pin inside the mod.When it did this it arched for a seccond.I checked the battery voltage and it was normal,and the mod seems to work fine but is it possible it could be damaged or dangerous now ?thanks anyone who can help me

So I didn’t hard short the battery?And you don’t think it could damage my mod and make it unsafe?I don’t know anything about it and I’m really worried one or both are damaged and or dangerous
I'd rekey more on those that know batteries better than I.
As for the mod I don't think you caused any harm. Do you have more than one battery?
I'd put a different one in the modand try it.
Being regulated it will work or if won't.

Sorry, brain fart. I realize now you said it works fine, so you're good on the mod side.
Apologies for my lapse.

I (probably not a good idea at all but I wasn’t thinking)put the battery in the mod earlier and they both work fine but I didn’t know if it could have blown a fuse or something in the mod that I wouldn’t be able to know about until I had a short circuit or something.Its working great but I don’t know if there could be hidden damage
I doubt it.
If the board came on and it fired, the mod should be fine. Nothing to worry about.
I'm not as confident in my battery knowledge to say "It's great!"

Ok great thank you so much for the help it’s greatly appreciated !
Late to the thread, but I assure you if you had hard shorted the battery you'd know it. Still it was a close call, so let's try not to do that any more, shall we? Welcome to the board.
Hi, welcome to ECF, your mod and battery should be fine but it was wise to ask the question especially if you are a new user. I'm in agreement that if the battery had shorted, you would have trashed it already, and if the mod is working fine, it sounds like there was no damage. I wouldn't worry about it but it's always good to ask and be on the safe side (there aren't holes in the wrap from the spark or anything, though, right? If there are you may need to rewrap that battery which is fairly easy to do... 
Good luck and welcome, hope you continue to enjoy vaping!

You also don't have to worry about the blown fuse. I'm not sure there are any fuses in these mods. But if there are fuses and you managed to blow one, the mod wouldn't turn on or at least some functions wouldn't be working. It's also a very good idea to ask about anything you're not sure of. That's how most of us learned.
Let me tag @Mooch, our resident battery expert, to wade in with his opinion on that battery.
The problem with batteries is most of the "important stuff" is on the inside of the can where you can't see it. There "could" be damage that isn't readily apparent visually on the outside.
You can measure the voltage to indicate if it is within normal range (3.4 - 4.2 volts), and inspect for burnt markings that often come from electrical arcing or melting of the insulation wrap. You might have witnessed some venting of gas from the top of the battery, or felt some unusual heat from the battery.
Mooch did an excellent explanation of the two main events that can happen to an abused battery -- venting and thermal runaway -- in the below article:

The battery didn’t emit any gasses that I could see ,no burn marks either ,only a bit of the wrap at the top melted a little but it’s still covering the top ring.I haven’t and don’t plan on using the battery anymore though.
Hello & Welcome,
Your here to tell the story, so things couldn't have gone that wrong.............
Your getting Vapor out of your tank and mod,,,,, That's a good sign.........
At least some of the DNA boards have fuses.
Yes, you did hard short it. The mod won't be damaged by that, as described, but the battery was not happy. There's no easy way to tell if the battery was slightly damaged though.
If the battery holds its voltage overnight and isn't warm when not being used then there is a decent chance it's ok. There's no way we can be sure though and you are responsible for your own safety. If that battery makes you nervous, replace it.
Thanks for the reply !I decided to recycle it.Yes, you did hard short it. The mod won't be damaged by that, as described, but the battery was not happy. There's no easy way to tell if the battery was slightly damaged though.

Welcome and glad you joined.
Smart decision.
I have provided a little more information which might help choosing/evaluating batteries.
