My fuel gauge PCBA is working properly, 2-in-series LiFePo4, HDQ communication port and 4 LEDs.
The cells were fully charged, once I try to discharge it, the SOC goes to 0, and the remaining capacity goes to 0 also. My discharge current is about 6.5A. When I reduce the discharge current to about 1 ~ 2A, the reading seems to be OK.
What have I done wrong? or what can I do to not let it reset.
The .GG file is attached, please rename the extension to .GG to try.
