Description
One of older projects imported from Eagle. It has three 18650 cells onboard and can charge them. Relays are needed for switching cells in parallel for charging or in serial to give 10-12 volts for LED strip. Although USB connector used, it needs about 7,5 volts for success charging due to used LM3177 voltage drop. Project was made and tested from Eagle, but imported to EasyEDA without any tests. See [video][1] of how it's working. If you want to replicate this device ask me for firmware maybe i will find them. [1]: https://vk.com/video197748989_456239027
