Removed R612 (This disables the stock charging circuit from reaching the controller board). PH2 connector is soldered to 5v and GND on backside of motherboard PSU pins. Battery charger board (little USB-C board) has opposite PH2 connector soldered to its inputs. Battery charger board has another PH2 connector soldered to B+ and B- (Battery connection) **Note this PH2 connector should be he opposite of what the battery has installed.** Battery charger board has 30 gauge wire soldered to Out+ and Out- (Connection going to 3.7v to 3.3v stepdown) Out+ is soldered to V1 on stepdown. Out- is solder to G on stepdown. 30 gauge wire soldered to VO and connected to + on controller board where battery originally was. 30 gauge wire soldered BT- on controller board where battery originally was and this is connected to G along with the wire from step 8 to G on the stepdown. Add battery and done. Extra note: B+, B- V1, VO G, +, and BT- are listed on the various parts. Refer to the listed parts. Please note while I can verify the parts listed above are color coded corrected and the connectors are +/+ and -/- some weird stuff happens on the internet and some brands / companies invert colors and/or connectors. When modifying circuits and/or adding to them please double check with a multimeter before suppling power!!! I am glad to help if you need assistance past this!
