High batt rollback start 29vWhat does this actually do?
A lead battery is charged at (not "to") 28.2 Gel or 29.4 AGM Max. After charge it falls from this in a curve hat starts fast and gradually slows to 12.85V. So not sure how setting this helps anything?
Lithiu ion phosphate should reach 28.8V peak while charging. Then almost imediately drop to around 3.4 something per cell. So again, what is it for?
Additionally, If I do a fast turn in place or wheelie, the lead battery drops to 24.xxV in an instant or less depending on impedance. And then recover fast to around 25v and then climb over time for the next couple of hours. I can actually get it to hit 18 volts whie fully charged.
Batt gauge minimum 24vIs that under load, ignoring this, or while I do the above? And for how long?
Batt gauge maximum 28.8vThis is for the display. So your guage will always read around 90 to 95% full when fully charged around 10 mins after disconnecting the battery charger?
Batt gauge low voltage warning 24vI can make it voltage actually read 18V by repeatedly wheelying or even a rapid turn in place when FULL.
Watch vid. Note that the NOW voltage is the large number. The 3 lower smaller number are peak values. High, average, low.
This is because of internal battery resistance.
Note that this has just come off an overnight charge. I dropped it to 18.X Volts - lowest figure really easly. Download to desktop before playing.

They are there because somewhere there exists a programmer that doesent understand ohms law or batteries wrote some "exact" code! The more nonsense they add the better or more clever they feel.
Batt gauge high voltage warning 29vThis will go off if you spike the voltage upwards by slamming in reverse to slow down due to regenerative braking. So whats it for?
Cut off voltage ?What do you want this for? Look at the vid above. Does it cut of instantly, or average over time, does it only take a reading when stick is central? All these things determine whare is at al this should be set and again we dont know. And its just down to a programmer that hasnt a clue.
Batt gauge final charging threshold 28.8
Batt gauge charging detect threshold ?
Batt gauge minimum charging threshold ?These things are a way to allow the system to better guess what stage the battery is in. All pretty meaningless really. Esp as lithium behaves diferently to lead... So these things wont help you uch or at all. Quite the contrary. They dont much help on lead either! This nonsense is why battery gauges are useless.
