First of all thanks, this is an awesome project for some one like me who is getting started. After googling around about LiPo batteries (and why mine has 2 plugs) I've read that charging them without a balancer can be really dangerous. Are there adequate protections in this circuit so my house does not burn down? I'm not saying this to be a jerk, I love this project and appreciate your effort. I have a Lumenier 1300 mah 35c 11.1v battery. Thanks in advance.

[@Circuitdigest]

The PCB has a dedicated battery charger chip, the infamous TP4056, which is cheap and easy to find. So no need to worry about charging the battery. But keep in mind that the current design doesn't have any over discharge protection. And the drone is designed for 1S battery not for 3S battery pack.

[@kunaldhar6713]

0.6x25 means your 600mah 25c battery can safely deliver 15 amps at FULL CHARGE or 1.5amps at 10% charge 0.33x25=8.25 (or 8) if in total your 4 drone motors consume 8 amps at full throttle then that's a useable capacity of 270mah out of 600mah battery therefore 60/29.6= 2 minutes of minimum flight time at full throttle safely, tho if you are gentle then that's subjected to increased useable capacity and flight time as well as reduce losses by less heating Pro solved it for pleasure, hope it helps

[@kunaldhar6713]

You’re driving a mosfet with just the IO pin of the ESP32? Arent you worried about the massive charge needed to drive the fets?

[@Circuitdigest]

No. If we consider 20mA as GPIO current limit, the Rlimit = 3.3/0.002 = 165Ohms. And if we calculate the RC time constant = Rlimit*Cload = 165* 5.E-11 F, 50pF from the MOSFET data sheet, = 8.24nS. Since this is way below the rise time of the MOSFET(15nS) we can eliminate the gate resistor.
