​Hello, It is a good project. I have couple of LiPo batteries and I use them on same way but not on one board :(.
I use TP4056 with protection board DW01A and I solve the problem for low voltage protection for LiPo with use of voltage divider on 100 ohms (R6) resistor on pin that read VCC.
I see this from one Russian blogger, he use diodes for voltage drop, but I thing why to not add one resistor to ground :).

I have an iPhone, and I have to create a voltage divider to charge it, will it work if i attach this part at the end with a usb port?:

@DocFilo How many volts does it need on the data pins

@DocFilo && @SamiAlla

If you use your addition to the circuit iPhones will charge at around 500mA. You can increase the charging current up to 1A by changing the R8 value. If the voltage on D- is 2.8V (R8 = 43K) your iPhone and other Apple devices will charge at around 1A.

Good Luck!

Hmm... seems I can't edit my comments ;)

If the only thing you want to charge is your iPhone you don't need the protection circuits because you can't overcharge the LiPo battery in your iPhone.
