Will the mesh boards have fuelgauge?

Can Argon (or Xenon) Read the Battery State?

In my opinion, the FuelGauge is pretty accurate. Several assumptions are made, and you would have to make the same assumptions to calculate a SoC independently. I think the misconception comes from the firmware’s default ChargeVoltage at 4.11V for various safety reasons. The SoC shouldn’t be mapped or re-calculated just because 4.11V is the Vmax selected for charging. The SoC does a good job as it uses the known Li-On characteristics to approximate the available chemical energy at any give t…
