Tweezers and clips similar to those available at Hobbyking. Deliver time & cost were too high so I decided to generate my own version. Works reliable as soon as you spend a bit of glue between clips and XT60 plugs.

Print 2 tweezers, one pin, assemble them gently, preferable when pin is still warm. Print 2 clips, put them onto the XT60 plug/socket Enjoy easy battery disconnection.
