Hi,
Completely new to it, I thought electronics was pretty so far as I was just wiring a single wire to GPIO pins of my Raspberry Pi, but I got scared when I read the datasheet for the BQ34Z100!!
I would like to check with my RPi (via I2C) running on Linux the remaining capacity of my battery pack, made of 2 x 12V / 110Ah batteries in series (i.e. 24V / 110Ah).
1. While the former BQ34Z110 supported capacities higher than 65Ah, the datasheet of the BQ34Z100 says "Supports Battery Capacities up to 29Ahr with Standard Configuration Options". Can I still use it with my battery pack?
2. If I understood correctly, I need to step-down the voltage to something between 2.7 and 4.5V. The documentation talks about LDOs. Is that the best option? Could you give me an example of suitable product?
3. What is the minimum of extra parts I need if I just want to be able to read the gauge ? (I don't need LEDs etc.)
Many thanks for your help!
