Hi I have a controller and recently it's been struggling to maintain power. Not charging and then charging. What I've now found is that on the back of the controller, the charging contact on the far right as you look at it the little spring strip that sits up is missing the little bit that dissapears back into the controller, so on a quick glance it looks ok but on closer inspection it's missing the 90 degree return bit. I can only assume this is causing my problems. My question is is there any way I can get around this? I don't need the battery to charge I just wanted the unit to power.
