| [title] Add Usb Lipo charging board | |
| [* black] First of all test the functionality of the charging chip alone: Plug it into a usb charger and verify that both the red and green LEDs light up. | |
| - | [* black] To make sure the usb charging port is at the desired position and depth in the case, take |
| + | [* black] To make sure the usb charging port is at the desired position and depth in the case, take measurements (also already for the hole placement in the case) or follow the measurements in the pictures to place the lipo charger. |
| [* black] Glue the lipo charger on the back side of the circuit board: I used foamy double sided adhesive tape but had to add screws to fasten it properly. Glueing the boards together should do the trick better, but can be trouble if the lipo charging board needs to be replaced) | |
| + | [* black] Make sure the two boards have a strong connection since it will have to take the force of every insertion and extraction of the usb cable (check by inserting usb cable and carefully tugging at it) |
| [* black] Solder the 5 wires from the charging board to the shaver circuit board (to prevent melting the other wires with the soldering iron solder the green and black GND and BAT connections first, then the red LED wires, and finally the GND wires for the LEDs) | |
| [* black] Test the functionality of the charging chip again, by plugging it into a usb charger: both the red and green LEDs should light up. | |
| [* black] ***DO NOT SOLDER CONNECT the marked section which enables 500 mA charging current. It seems to be too much for the charging chip, which will overheat and break, short circuiting the battery!!!!!!*** |
