Hi all, I am using:
Arduino Mega as a controller (5V)
Lipo rider as battery charger and to provide 5V - 1A to the arduino
3.7 V 10000 mAh Lipo battery, 1C
EFCom GSM shield (500mA average, 2A pulse )
my problem is, this lipo rider pro they claim its able to provide up to 1A max however, the GSM shield needs 2A (in peaks time), in addition to the arduino power and the sensors (around 100 mA).
I tried powering up this system with a 2A powerbank but it didn’t work, I powered it up with 12V, 2A adapter and it works fine! I couldn’t understand why the powerbank is not able to power it up although the current in both is 2A.
my main question is, how to power up the arduino with the GSM shield using the battery and the lipo rider, do I need to use a capacitor? is there a way to boost the current? what is the best way to do this?
here is a picture of my circuit:
