An example of fixing the missing resistors. I did this very lazily. I used one of those cheap little C Ports that are all over Alixpress and Amazon. you will want to you like 28awg or smaller. You'll want to use superglue to secure the wires after you know it works. The cc pins were really small on mine so the solder is not holding onto much. I also upgraded the battery to 1800Mah. This requires cutting the internal plastic and the clear lens. The stock battery was very small, so even going to a 1000Mah would be an upgrade.
