Lipo Battery Temps

[tuclai]

I just got my MMM v3 back yesterday and was out testing it out today. I notice on avg motor temp is 130, battery is 120 and ESC is 120. I was pushing it all out for about 15-18 minutes and the LVC kicked in. So I temped right at the end of the run and my motor is 145, battery and ESC is over 130. My question is this, if the lipo is running at about 120's throughout then all of a sudden it shoots up to over 130 before LVC kicks in, is this normal? I am using an NEU Energy 4s 5000mah lipo. The battery was at 13v when I plugged it back in the charger. No puffing of the battery was noticed. I am using MMM v3 with NEU 1515 1.5d motor. Motor timing and intial accelration set to lowest on ESC.
