•

To identify charge circuit damage, the battery terminal voltage jumps up to the charge voltage while the app shows

no current and a much lower voltage, the exact discrepancy depends on the actual block voltage.

•

It is normal to have a small discrepancy between terminal and battery voltage shown in app during normal

operations.

SoC is inaccurate:

Lithium batteries have a flat discharge curve making it necessary to estimate SoC based on an algorithm considering

numerous present data points and historical usage factors. Low currents and usage. parasitic draws, may result in an

inaccurate SoC calculation.
