That sounds like the battery performance you’re looking for. Test it a few more times over the coming weeks to make sure those numbers stay consistent, and you’re good. Your hesitation could be completely unrelated! As for your shifting, it all depends on how much gas you’re giving it, uphill/downhill, etc… If you don’t have a tach, a good rule of thumb is about 4-5 seconds of ‘normal’ acceleration in every gear. Don’t worry too much about short-shifting. These engines are made more for torque at the low-end, so not much sense revving them out unless you really want to hurry! You’ll get to know it by ear.
