- Arduino Mega as a controller (5V)
EFCom GSM shield (500mA average, 2A pulse )
The problem is, the specs of the LiPo Rider Pro claim it is 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.
I also tried connecting the GSM shield directly to the battery (which is 1C and should provide up to 10 A, but it also didn't work.
The 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 for short term power storage? Is there a way to boost the current? What is the best way to do this?
Here is a picture of my circuit:
