2 years ago Hi, please excuse the very late reply. The battery % by voltage requires an extra lua file where you specify the discharge curve. The script looks for a file named modelname_batt.lua in the cfg directory (same place as the script config file)
the content is:
local voltageDrop = 0.6
local useCellVoltage = false;
local dischargeCurve = {
{3.48*12, 0},
{3.51*12, 10},
{3.58*12, 20},
{3.66*12, 30},
{3.76*12, 40},
{3.81*21, 50},
{3.88*12, 60},
{3.93*12, 70},
{4.03*12, 80},
{4.08*12, 90},
{4.20*12, 99},
}
return {voltageDrop=voltageDrop,useCellVoltage=useCellVoltage,dischargeCurve=dischargeCurve}
The script uses an 11 points discharge curve mapped into the array voltageDrop acounts for under load voltage sags, adjust per your needs useCellVoltage specifies if the 11 values you enter in the array refer to cell voltage or battery voltage

Horus V1.9.5: using PX4 and one power module on Power 2 of PX4. Yaapu config: dual battery config - dual with alert on B2 (didnt find any other way to work with B2 only) enable battery % by voltage: YES default voltage source: fc Battey 2 count override: 3 cells
expected behaviour: battery % changes according to pack voltage displayed. actual behaviour: battery shows 99% regardless of voltage (12.6V down to 10.0V)
