Upgrading cheap LED Juggling Balls

Many years ago I bought 10 LED juggling balls from Oddballs in the UK. At the time, the special they had on was pretty good for bulk orders, but even today the balls are pretty cheap, if a bit basic (11 Pounds UK). The balls, being cheap, did not last. They have replacable batteries and the screw-in plug to close and switch on is a terrible design. Recently one of my upgraded K8 juggling balls broke somehow (a short from being dropped too much?). I fixed it up but I decided I needed some spares in case this happens again just before a show. Luckily I had some broken Oddballs balls lying around. I used the super bright LED’s from the ball and upgraded them with a 110mAh battery and Jack Switch for switching on/off and charging.
