Hi Keith,I updated the schematic as per your suggestion.Is it all perfect now ?
View Instructable »You are right.They are on the two different side of the board.

Hi friend,Recently I made some changes in the schematic to monitor the battery voltage.Another change in the schematic is use of 18650 battery instead of 14450 battery.I have one doubt, In the TP4056 board, Out- and Bat- are not connected with each other.The Out- is connected to to Wemos GND, so if I want to monitor the battery voltage,where should be the voltage divider GND connected ?As the Wemos board have one inbuilt voltage divider ( 100k, 220k), I am just adding one more 100K resistor to compatible with maximum battery voltage (4.2V). I am attaching the schematic.If any changes is required, please suggest me.Once the schematic will be finalized, I will order the PCB.Thanks !
Your understanding is correct.The BMS used in this project have balancing function also.I purchased it from Banggood, where it was clearly mentioned.
Sorry friend, I don't have any experience on designing the BMS.
Thank you for finding my mistake.Now corrected.
