Capping off battery leads?
 
I've got a 2 cell LiFe battery for my transmitter that has way too many leads -- it's got a balance lead, two small receiver leads, and a big Deans style on it. All I need is one receiver lead and the balance lead, so any thoughts on what type of terminator to put over the other wires? My transmitter battery compartment is pretty small, so I'd like to cut most of the length of the wires off.

get large enough heat shrink tube to cover battery. then open pack (remove heat shrink that's on it).. desolder the leads you do ont need . put new heat shrink on and your Golden

Cool, good tip! I'll try that out. Any safety precautions when desoldering the leads? Just heat up the wire and pull it out when it desolders?

Yep, unless you have like a helping hand or a small clamp/vise (jig) , I'd tape the connector to your workbench, then use your free hand to pull the wire as you desolder it.

If I bought a battery with many connectors, I would just remove all the connectors I don't need. GL

Got around to doing it today. I couldn't desolder the Deans and the extra receiver wire -- I don't know if the battery was acting like a giant heatsink, but my trusty 850W soldering iron just could not get the solder to liquify. In any case, I just cut them off at the solder point and taped the battery back up.

I couldn't find a good heatshrink wrap -- the one I had was almost like vinyl and way too thick/big, so I just wrapped it in electrical tape and I think it's actually pretty good now.

Thanks for the help guys!

you have a 850 watt solder iron and still could not get solder hot enough ? hmm. was it a pencil tip ? My wedge tip 80 watt unger can get almost all solders flowing..id still find the correct heat shrink tube for this job..

Never heard of a 850 watt! :confused:

Yeah 850W sounds like a torch for pipes. :lol:

I use my 65W soldering iron and use Deans all the time.
For heat shrink tubing, I think I bought an assorted set by Anytime Tools from Amazon. It is very similar to the ones that come with Dean connectors in various sizes.

Id like to see that 850 watt solder welder....http://www.batteryspace.com/PVC-Heat...Wrap-Tube.aspx

LOL, sorry 850 degree iron, I used a chisel tip, only 60W. Thanks for the link on the shrinkwrap, the one I got was way too big, but they have some nice sizes there.
