No I dont do scooters. Only powerchairs. I dont even know what software to use!
If I were you I would stick a voltmeter on the battery and accelerate hard up a hill. If the voltage falls below around 20V then the batteries are junk. And just because they are new - even brand new doesent change that. Most cheap generic AGM batteries are frankly rubbish. Look for the impedance. 2.5MOhm is good. At least as good as you will find. Such as Odyssey. A battery with an impedance of 5mOhm is TWICE as bad, double the volt drop under load. One with 10mOhm has FOUR TIMES the voltage collapse as you try to gun it or climb a steep hill.
With batteries you get what you pay for.
