I'm riding in minus zero (Celsius, sorry !) temperature now. I never had a "long" range capability on my 11.4DS but I'm riding as hard as I can as it's always a war between cars and bikes here in France and I have several parts of my trip at 120km/h, no highway tough. So my range is 80-100kms but as I say it's normal for my ON/OFF type of riding. And this is the range I need to go working.
But with the low temperature I have noticed that power is lower, my accelerations are slower, it's noticeable, and range lower. For the range I can't be sure as sometimes I have to ride as smooth as I can because there's still some ice patches I must avoid when riding very early in the morning before the salt truck pass, and so I adopt an economical riding !
Have you noticed also the power decrease with very low temp ? I've noticed it also on my RC model aircrafts which run also on LiPo, must be a chemestery things ?
