I wanted to power up my raspberry pi with the only lipo battery I have which is a 11.1V 3S 2200mAH 30C Rechargeable LiPo Battery.
I done some research, and most of them used a voltage regulator to step down the voltage. However, I'm facing dilemma of choosing between two voltage regulator:
- LM2596 3A DC-DC Adjustable Step Down Voltage Converter Module
- XL4015 5A Adjustable Step Down DC-DC Module
I'm worry that:
- Will LM2596 become too hot when supplying power(2.5A) to raspberry pi?
Some suggest to use XL4015 5A because it won't be too hot when supplying power to raspberry pi since rated current for raspberry pi is 2.5A. However, I'm worry that will the raspberry pi draws too much of current since XL4015 can supply max 5A.
This is because I found out from one post "The RPi 3+ board is protected by a special fuse which permits no more than 2.6A. If the user attempts to draw more than that then the RPi will become unstable, crash, reboot etc." [https://www.raspberrypi.org/forums/viewtopic.php?t=230915]
Lastly, after I adjusted the output voltage to 5V for raspberry pi (when lipo battery is fully charged), will the output voltage from these voltage regulator drops if the input voltage from lipo battery drops (after powering raspberry pi for a period of time)?
