3.7v here too. If you go by 4.2v, then your actual speed will be slightly slower (or alot slower, depends on how good the batts are really), but it also means you are geared lower so hence the lower temps really. I never really factor in tires ballooning, if I did then I would be geared lower again too, meaning lower temps and roughly the same speed as I originally geared for once you add in the ballooning.
