LogBook and Gauge tuning

Here we have a report to show how the bike is working.
We've made a basic correlation to have an idea of the residual energy.
We've also tried to check the energy loaded to validate the estimation.

This is the link to the document: EBike.logbook

We also detected that the gauge was not adjusted for our battery.
It seems that our battery produces 90% of the energy between 54V to 51.5Volts.

But the green and orange LEDs were ON even when the battery was discharged (below 51V). The gauge was probably designed to detect voltages from 43V to 49V, not for a LiFePO4 battery pack.

We've slightly modified the circuit:
1st) A 5.1 zener diode has been added to make the green LED switch off at 53.2V
-> Now it indiacates that there is more than 66% of energy left.
2nd) For the orange LED it has been a bit more complex.
A TL431 chip turns on the LED when the voltage in reference pin is over 2.5V.
Originally this pin had a voltage divider with 3 resistors: 100K + 5600 + 590 (ohms). The comparison voltage was fixed too low. We have shortcircuited the 590 ohms resistor, and now the comparison voltage has increased to 52.3V.
-> Now it indicates that there is more than 33% of energy left.

The references are approximate, and visible when you release the throttle.
