Hey Linc,

a motor with lower kv is running cooler because the efficiency of electric motors is going down with rising amps. So if you got 120A on 3s, the efficiency will be around only 70%-75%, that means from the around 1100W you battery delivers only around 800W go to the pinion and 300W are going into heat. At 80A on 5s, the efficiency will be at around 85%, so from the 1300W your battery delivers around 1130W will go to the pinion and only 170W go into heat.
