Guys,

How much battery power do these heaters use? I have been connecting to a 12V power source up till now, but I want to wire it to an additional battery in my starter box. Just curious if they drain the battery hard core or you easily get a day of racing/heating out of it without the fear or killing your LiPo?

BTW: I am looking at using a 5000mah 4S LiPo
