Default Resolder Lipo

I have two good lipo packs for my Robbe Hydrasnake, but the balancing wires have broken off. I have ordered the stuff I need to solder them back on, and I'm not bad at soldering, but I have never soldered lipos before. What I'm worried about is, how much heat can I apply with the soldering iron? Could the heat from the iron make them puff?


Hoping for answers as I really would like to salvage these lipos

Jesper,
Couple of things, you need to check if you haven't already, to see what they used to solder them on with. Often they use aluminum solder vs the regular tin based solder we normally use.
If so you will need the aluminum solder and flux.

If you are careful it's not hard at all to do. I tin the wire, apply a little flux to the tab, place the wire on the tab, and touch the wire with my solder pen. 2 seconds at most and it's done.

Hello, Thanks for the answer

I'm already done I ordered  aluminum solder and flux, and it arrived in the mail earlier today!
It was a bit tricky with the old solder, but I took my time and removed all the old solder.

The old balancing wires was to short and stiff, so they broke off right outside the shrink wrap.
The new ones are much more flexible and I made them a bit longer
Also had to replace the negative main wire, that was not as easy as the balancing wires : /
