Hi!
If somebody would be willing to have a look at the drawing I made, and to let me know please if everything would be working properly? Thank so much!

A circuit diagram showing what the connections actually do would help. I for one am not going to track down the boards information from the picture to see what the connections are for.
I tested this and it all works fine except one thing: batteries won't charge. Also, there was one black wire soldered to P- when I first time opened the casing of this device. I never figured out where was that connected but it must be the reason why the batteries won't charge.
Here is the image:
Any idea where should I solder that end of the wire please?
