A cheeky bit of help

[shep]

Hello everyone, I had my first race at the club on thursday the 6th, Had a brilliant evening but now looking for abit of help. The + wire coming off my esc which connects to my lipo is wayyyy to long. It works fine but makes it tricky to get the body seated correctly and I was wondering if someone would be kind enough to help me shorten in. I don't have a soldering iron or a spare bullet connector (i think they are 4mm but not 100%).

I know it's a cheeky ask but would rather learn how to do it from someone who knows what they are doing rather than muck it up myself, beer tokens or a kfc in return . I will be coming down on Tuesday to help out and then on Thursday.
Thanks
Harry
