many of those sensors are probably voltage sensing for the branches of the entire bank for balancing too.
From what I have noticed, unless you are a total fatass, riding does not really affect the battery much at all. Ive done some stupid riding on my bike, miles at high speeds, outside temp was low to mid 80's F, got off and immediately felt up the battery pack, motor and inverter to see what I did to it. All were barely warm to the touch TBH. I weigh ehh 180 ish Lbs.
Unless the temperature is like 100 degrees out and you are doing fast charge, 90 mph for 50 miles, fast charge - 80 mph I can't see how you'd ever get your batteries into the red zone. Well unless you were on the track too of course.
ALL packs are going to taper way down towards the end of their charge to give the batteries a chance to actually absorb the charge, and the voltages to settle down to more of a realistic value and not a hyped up because of the charge on it. This also lets them trickle in the balancing charges to get all the banks evened up.
