What happens with SOC, SOH and Hx values if two batteries are connected simultaneously?
Well, SOC will be wrong. It will drop like it would according to wasted energy. But then it will stop
dropping at 3-4 bars left. And then it keeps that for long. Until it starts dropping again.
SOH value will recalculate up and up. Until 103%. Which is maximum. Even though actually, there
is more kWh of energy available as there are actually two slightly worn batteries.
Hx value will recalculate to realistic value. It appears, that Hx value is the resistance of vehicle's
battery pack. 100% is factory default value. In case of two batteries, it will skyrocket. But it will be
around the average of two separate batteries (so in case of two new batteries, it will be 200%).
