Batterycase + Charger for Squeezebox Boom

This is a case I've made to insert 3*18650 LiIon cells with a built-in charger at the back of a Logitech Squeezebox Boom, making it autonomous. PM me if you want the electronic schematics as well

A friend made a much better version and added a cutout for the ethernet plug, so I've added them (v5)
