Do Not Short A123.. - RC-Monster Forums

aqwut · 07:58 PM

I just assembled the 6S1P Fully charged pack.. and the ends just happen to touch, and crap.. my eyes was flashed, and things was blury for about 30 seconds... I thought my retina was damaged... I was scared.. is there some kind of plastic/rubber cap I could use to cap off the 6.0mm connectors...?

Wow! That was a BIG spark! Good thing nothing got in your eyes, that would have been bad.

I usually fold a piece of electrical tape over the male connector when the pack isn't in use or I'm working on it.

I'm using tape also, but something like a cap for the nitro bottles would work great... I want something that looks neat... I'm going to take a browse through home depot tomorrow...

I think you should be using female on both + and - on battery...

You should never EVER have a battery wired with a male end. Assuming those are the +/- battery plugs, why is it like that?

You can easily put the packs in series if they're like that.

You got it bro, I need it for 12S, makes an easy connection....

MisterT, crap man... near a gas tank u are lucky...

Lutach, I bet it would probably put a nice dent on the pliers... I couldn't imaging what a 30C 5000mAh lipo pack could do.... scary now to think about it.... I know it scared the crap out of me...

I never mentioned this, but when I shorted my pack I was

and afterwards I was even sweeting cold. It freaked me out for a moment and I have a lot more respect for them. I didn't get scared whith 220V and 12V 1000A (High power Competition batteries), but the A123 pack had me scared. Good thing for rubber handles

Exactly that, it was still in my hand when it happen ...

This is what I don't understand with the MMM. It has female plugs all over it. Shouldn't is have male ones on the battery side.

aqwut · 08:51 PM

I'll NEVER put both males nor females on the battery.. with my luck, I'd connect them reverse polarity and fry everything... I just need a cap for them, this is kinda nice because I don't have to use pig tails to connect in series... just one to another... all my ESC are wired the same.. and all the batteries are wired the same...
ESC: Male - Negative, Female - Positive
BAT: Male - Positve, Female - Negative

Before, I had the batteries all Female.. but A few times I connected them in reverse... and fried 2 Schulze....
Would you be afraid of connecting them wrong, if using both females on the battery?...

Brown trouser time...

I got a wicked spark when I accidently shorted my cheapo lipos a few months back- no damage done, but it scared the crap outta me for certain. I think something like a tire valve cap from a car or bike would look okay (enough designs to choose from). Or those little rubber caps you get on the bottom of clothes airers (look like little bullets).

MTBikerTim · 08:55 PM

I have seen it done the way you do it aqwut. I would say make your wires different lengths by an inch or 2. That way they will be far less likely to touch. You could even shink wrap the wires together close enough to the plugs so it would be almost impossible for them to touch.

aqwut · 04.21.2008, 08:57 PM

Thanks... I'll take a browse, at the home depot for those things...

Cr*p, it's a little too late to shorten the wires now... I should've thought of this before... takes a long time to solder 10 Gauge wires on them bullets...

BrianG · 04.21.2008, 08:58 PM

...or you can use those new SuperDeans they have out now rated for 100A continuous.

Oh wait, that was a dream...
