Do what I say, not what I do

[BHChieftain]

Hey Chief , I am glad I found your post.
I think I shorted one of my lipo leads also.
My question to you is: do you simply cut off that fried lead and solder a new one
on? Thanks, Glenn

Yes, I clipped the wire just under the connector, restripped and resoldered a new one, then OBSERVED CAREFULLY when I went to recharge/balance it...

I got lucky-- my packs were fine even after that incident.

I use SIX 3s packs in my DF40 copy to run 9s2p. I arrange the packs one on one side behind the esc, two on the other side, and three in the center. I series the three perimeter packs and the three in the center and then parallel them together. Needless to say, there are a lot of wires floating around in the same area and it would be easy to grab the wrong one.
I have a rule that my kids and wife know well:
*I dont talk while hooking up the batteries*
Unfortunatley bystanders arent familiar with my rule but they figure it out soon enough

If you didn't fry the lipo as well - yes. Check total voltage first.

Oops I mean, fried connector.

So Chris and I are setting up our boats at the lake getting ready for a sprint. We get on the topic of connectors...

ME:
"So Chris, one problem with running bullets like I have is that sometimes guys inadvertently short out their lipos when hooking them up in series"

BLAM!

CHRIS:
"You mean like that?"



Here's the connector after just a split second short. I think I'll change my connection order to prevent this in the future-- I was connecting the two lipos together first, then connecting the lipos to the ESC (here is where I ended up connecting the other lipo leads together...).

If I first connect the red lipo lead to the ESC then I can't end up with a short...

Back to the soldering iron...

I bought a big bag last time from HobbyKing with my LiPos...love those guys!

[forescott]

I love em! Thet solder easy,snap in and out easy, and dont require any shrink wrap. They are kinda pricey here in the u.s. but hobbyking sells them for less than a couple of bucks a pair. I usually order a dozen or so when I order lipos from hobbyking to save on shipping.

How come I dont see any of you guys using ec-5 connectors. They are rated for 120 amps, and are made for dummies like me!

Those are what I use in my VS-1 and couldn't be happier!

I think we have all done it at least once. My solution now is to pay attention. Don't be distracted! I agree that the pos/neg to the esc hooked up first is the best when running series!

[JMSCARD]

I found the easiest way to keep from shorting out your connectors is just totally "slowing down" during the connection process.... the bullets are fantastically easy to use as long as you take the time to use them properly... I too have shorted my connectors... but after a couple times you tend to pay a little better attention:) keep the bullets....

I have a hydro where the batteries (2 x 2s) are right up under the front cowling & I have to reach up under there to plug the leads into the ESC. It's hard to see up there with my hands in the way. Once, after thinking I had hold of the red from one pack & the black of the other (to link them in series) I soon found out when I tried to plug them in that they were both from the same pack.
Just like you Chief, I was talking to someone at the time instead of paying attention to matters at hand.
Luckily the battery survived, as only the edges of the connectors touched but I had to replace both connectors. It was a tense 15 minutes waiting to see if the pack was going to swell or not.
Cheers.

EC5 5mm connectors for me too..no heat and tight fit with no mistakes on hooking batts...

[Chilli]

I do the female bullet on the battery positive lead, male on the negative like many of us do, but still screwed up every once in a while. Thats because I always used black shrink wrap on all the connectors. As soon as I went to the red shrink on the positive leads, black on negative (controller and battery) I have never gotten close to a short.

Ohh, I'm liken' that idea!
