Hi,

Would like to enquire if anyone knows how to solder a t-plug (dean connector) to a Li-Po Battery?

What are the steps and are there any precautions or issues I should note? Thanks a million.

Regards,

Peter

Same steps and precautions you would use on any other battery. Don't let it short out.

Thanks for your reply... but how to not get it short?

sorry I'm new to this so can't too clever or smart on the details.

The big issue with LiPOs is that they can be ruined by shorting them, from what I've heard if only for a moment, so the deal is as I see it is to make sure and only strip and solder (and promptly shrink wrap) one lead at a time.

Also, check out Post#7 in the below thread - it's the golden rules of soldering

Shorting, as in a short circuit, would be allowing the negative and positive battery wires to directly touch each other. As mentioned, work on one wire at a time, being sure that the 2 never make contact.

One common mistake (so I've heard!) is to cut off an unwanted connector all at once, the wire cutters cause the short.

That was a great soldering how-to you linked to. But I have question. I'm going to start using flux now, so if you use rosin flux, does that mean then you dont want to use rosin core solder with that? I have two different 60/40 solders, ones rosin core and the others nc(no clean) core. Which is best to use with flux? Thanks.

No, you can use the same solder you've already got.
The fact of the matter is that, as the tutorial suggested, that flux is an etching agent that allows the solder to flow easier. Just using rosin core solder is fine for quick and easy work, that's what it was intended for, but there's so liitle rosin flux in it it's hard to use for anything more than just soldering two wires together. But for more of the heavy duty connections needed in RCing (much like plumbing connections) flux allows one to make that needed better connection.

Thanks. I just didn't know if too much flux was a bad thing. I guess its the flux I can see separating in the rosin core solder because theres a brownish color liquid that I see build up on the outer edges of the solder sometimes. So thats why I thought solder without flux, and then using liquid flux would work better.
