Lipo issue: Polyquest 30c 2s pack

[lincpimp]

That is the one I put new wires one, right? Kinda weird, Nothing looked wrong with it when I pulled it apart. Have you given the connector a good yank to make sure the soldering is good? (I use a very potent iron, but no one is perfect, right!). Do not yank on the wires as they go into the pack, not much strain relief there, Does the connector get hot when you run it? It was a traxxas connector, IIRC. May be dirty.
