Coming soon! BattSix DataLogger
Cart or NEV Battery pack voltages sent by bluetooth to your spreadsheet.
Really SEE how your batteries are performing!

Sample of about a half hour of data collected at 10 seconds intervals from BattSix Bluetooth with 'Numbers' spreadsheet on an iPod Touch then emailed to the desktop to create the graphs. The charger was switched ON for several minutes then OFF to let the batteries settle.

To plot 'at rest' State Of Charge with the spreadsheet these formulae will provide pretty accurate results. You need to modify 'batt' depending on the voltage of the batteries you are graphing. Above 100% is because it is being charged, below 0% percent means that battery is more than likely shot. You should strive to avoid discharging your batteries below 40 to 50 percent for longest life.
Six volt batteries... batt= Voltage X 2 Eight volt batteries.. batt= Voltage X 1.5 Twelve volt batteries... batt= Voltage
//AGM percent charge=((batt*92.2131)-1085.14)
//FLA percent charge=((batt*118.778)-1400.28)
//GEL percent charge=((batt*87.2093)-1026.16)

With Bluetooth OFF set up your spreadsheet with at least 7 columns. If you want to plot the data as it is collected, set up your type of graph and select the data range.
Go to the Settings app and turn Bluetooth ON, return to the spreadsheet and tap the top left cell where the data entries will begin.
The iPad is setting in an Eagle Golf Cart logging battery voltages of a Bombardier (behind the Eagle).
I had the charger ON for a short time, then switched it OFF.
