hey guys, so like my title says im experiencing battery cutoffs early…im trying to find the culprit.
i suspect its my aging batteries sagging when im close to the cutoff voltage but i dont think it should be this abrupt of a cutoff.
i run 2x4s zippy flightmax 8000mah 30c batteries as an 8s pack with cuttoffs set by vesc tool as 24.8 end and 27.2 volts start. now, when im at around 28 to 28.5 volts on my pack (usually when im heading home) i occasionally experience complete power cutouts when i accelerate anywhere past around 25km/h(makes it scary to get back home ) . i assume this is the battery cutoff, but when i check the voltmeter on my board the moment after it happens im atleast 1 volt above my cutoff start…so im trying to figure out why im getting these abrupt cutoffs when im seemingly decently above the cutoff voltage.
is this just the result of the fact that my batteries are over a year old now and are sagging heavily around my cutoff range?
