Silvan Fuhrer b53d2cdf39 battery: reset current filter when transitioning to FW (#22256) 
VTOLs consume a lot more power in hover copared to fixed-wing fligt.
The remaining flight time thus should reset if one switches from MC to FW,
as otherwise it takes several minutes until the estimate goes down.

Matthias Grob b87c5285e2 battery: weigh voltage based estimate more when it's low 
This is a minimal change to make it harder to crash a
vehicle with an empty battery if the capacity was set wrong.

The disadvantage is that the state of charge estimate will
fluctuate more under load.

We need better documentation and improvements to the estimation.

Matthias Grob 4f34207c4e battery_params: increase default empty cellvoltage to 3.6v 
Based on feedback that very often the battery is used down too low.
I observed this happens consistently when the cell voltage is properly
load compensated. The default load compensation before #19429 was very
inaccurate and resulted in unpredictable estimate.
After that if there is a usable current measurement and the battery is
within expected tolerances of the default internal resistance the
compensation is pretty good and 3.5V is too low for an empty compensated
cell voltage. That was seen in various logs where the compensated
cell voltage was already dropping fast after 3.6V.

In case the voltage is not load compensated the vehicle estimates the
state of charge a bit too low which is safer than to high
especially for a default configuration.

Matthias Grob 2c5a7ea118 battery: rather undercompensate for load 
than over compensate which makes the estimate to high and breaks batteries
beause they get flown for too long.
