Electrical Problem/Short
 

All right so heres what happened, I was preparing my gun for the day, and so I was putting my battery in the stock tube it is a King Arms 11.1 V 1100mAh 15C battery. So I plugged in the connectors and then they started smoking I immediately unplugged them and inspected. The Battery got Warm and the male connector on the guns end was damaged.

So now on to the questions.
I'm not an expert in the battery or electrical area
-Can I use my King Arms 1100mAh 15C battery again?
-Should I replace the existing wires besides the connectors?

Whichever was smoking, that part is fried. If your lipo is smoking I don't recommend you try and use it again. highly dangerous. You must have a short somewhere or that battery is no good.

thank you

Replace those connectors with deans ;)

I would say the battery connection is the most likely cause of the short.... If you say it was getting warm and you only had it plugged in for a couple
seconds, sounds like a classic begining of thermal runaway, which for that to happen requires the battery shorted with no load attached to it... Before you start plugging a new battery in there..

1) Inspect the battery on its own, look for any nicks, pinches, or even broken/crack sheilding. Move the wire and flex it, while looking at it.. this will allow any damage to be easily seen.
2) Inspect the connections, I would suggest replacing them regardless. Swap out to deans.
3) After all that.. inspect ALL wiring within the AEG, once again looking for cracked/pinched, nicked wires.. and if two wires run real close to each other, inspect those sections exceptionally well..

A few questions for you..
your stock tube.. is it metal? or plastic?
if metal.. something maybe shorting out to the inside of the stock. Once again check your battery and connection.. wires leading to and from the stock.

I have a metalstock tube it came with my UBR Stock

I only have one more question.
Can somebody properly guide me to putting the battery in correctly?
"I might have been putting in wrong"

Well this is very dependant on how your gun is wired..

If stock wiring is present, there is a standard practice that is usually followed
Black = Negative
Red = Positive

Try to match these up to each other (i.e. Black to black and red to red.)


Now most airsoft batteries are in series with each other. Simple way to explain that one is, stacking two AA batteries ontop of each other, with the (-) negative end touching the (+) positive end of the battery below it. This is Series. Doing this increases the potiental difference of the batteries.

The Bottom portion of the battery or combination of batteries, would traditionally have the Black shielded wire comming from it leading to the connector, and the top portion of the battery will traditionally have the Red wire comming from it also going to the connector.

I'm unsure if polarity is a case here, but yet again I've never hooked up a battery wrong either.

I've alwas done that in the 3 years i've been playing. I'm just new to lipos but i found out my batt is toast. I
m not sure what to do really weather to run anouther lipo or just switch back to the standard 9.6 to be safe. only shitty part is i have to take off the ubr stock witch is so nice. i think for the time being i'll witch back and play it safe. I'm going to read up on lipos and ask questions so if i come around the bend agian for a lipo i'll be ready for it this time.

You can keep using LiPo, but put a fuse on it if your running it straight off the wiring. And you should REALLY have a mosfet switch to protect your trigger contacts if your running 11.1v
and give this a read if you haven't already

Personal view: Lipos are nowhere near safe as most folks think they are, also consider this, a single lipo pack has cells in it as thin as chewing gum sticks, there is a possibility of these individual cells either breaking down and losing charge or worse if any of the cells are ruptured you run a worst case scenario of a serious lipo fire. Not something you want to mess with and sand will not help.
In the RC world, we use ceramic holders and/or lipo bags to charge the batteries.
Another down side to lipo, they have a minimum charge that they HAVE to maintain, NO you cannot shoot until your lipo runs dry, you're killing the battery. In RC we use a low voltage cut off and alarm, which, once it goes off, you have to disconnect, rest and recharge no airsofter I've seen with a lipo uses one.
The upshot to lipo; no cell memory effect, a little more enviro friendly and small size.

I have only posted this because I worry about lipo proliferation into the airsoft world and 60% of airsofters I've spoken to have no idea of the dangers of lipo.

I agree that most airsofters have no idea what a LiPo is, they just go "OH cool battery!" and assume it's the same thing as a NiMH pack.
My whole team uses LiPo batts, but we actually take care of them properly. And at 9$ for our standard 7.4v 1600mah, 20C battery, there's NO reason not to throw it out if you suspect it of being damaged :D

But we have all the safeties for LiPo batts available;
MOSFET + fuse + low voltage alarm
Triggermaster MKIII SW-COMP, either by itself or with an integrated low voltage alarm

And the low voltage alarms come either as a straight alarm, or with the option of stopping the gun entirely by cutting the voltage off at the MOSFET.


But of course, you have no know these things exist first lol
