Hey! Just finished putting together a Lily58 Wireless kit. For both batteries, I stripped the wires (as per guide I received) and connected to the B+ and B- pins. Each half also has a power switch. When plugging each half in, I can see the half in order to load the firmware and the lights on the half are active. When unplugging and using the power switch, nothing happens - no lights or anything showing on the screen. The soldering on each power switch looks ok to me so not sure it's a solder issue but I can always go back and re-do if this could be an issue. Any ideas? Thanks!
