I have connected 3 batteries (Panasonic NCR18650) in parallel to the LiPo+ pin on my electron. Everything works fine except the reading from fuel gauge is very inaccurate. When i connect an external power supply (12v connected to Vin) the red indicator led is light up and SoC reading increases from for example 10% to 60% but when i disconnect the power supply it goes back to 20%. My questions are now:
- Do i have to change something in the fuel gauge to make it work? (Restart when power source is detected?)
- I read the BQ24195 is only for single cell. Does it matter when the batteries are in parallel?
Thank you very much in advance!
