Lily58 wireless battery/power issue
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!

Since you soldered the batteries to the B+ / B- pads on the nice!nano, the on‑board power switch on the Lily58 PCB is now bypassed.
From the battery docs:
- damaged / dead cells. If you can, post close-up photos of the battery wiring on each nice!nano, or email them with your order info to hello@typeractive.xyz so we can inspect. You can also just reply to this message or tag me here and I’ll keep helping you debug.
“…you can solder the battery directly to the B+ and B- pads on the nice!nano, but you'll no longer be able to use the power switch.”(ref:
build-guides/lily58-wireless/batteries)
So flipping that switch will not turn the halves on/off anymore – that part is expected.
What isn't expected is that nothing happens on battery at all. A few things to check:
1. Polarity
- Confirm red → B+ and black → B- on each nice!nano.
- If you’re unsure, stop plugging it in until you’re certain; reversed polarity can kill the cell/charger.
2. Is the battery being seen/charging?
- Plug in USB to each half.
- Do you see the small charging LED on the nice!nano light up? (Usually near the USB port.)
- Leave it plugged in ~1–2 hours, then unplug USB and ignore the power switch; just tap reset or press keys. Does the display/keys come alive?
3. Solder joints
- Reflow the B+ and B- pads on the nice!nano (both halves).
- Make sure there isn’t a solder bridge between B+ and B- or to nearby pads.
If after those checks the halves still only work on USB, it’s likely either:
- a bad connection from battery → nice!nano, or- damaged / dead cells. If you can, post close-up photos of the battery wiring on each nice!nano, or email them with your order info to hello@typeractive.xyz so we can inspect.
