Hi all. As a newbie to large scale I am confused as to what 12S battery set up I should buy for my DBXLE 2.0, which will be running with ZTW BEAST Pro 300A 12S ESC and ZTW BEAST Brushless Motor 620 kV.I was looking at the Spektrum Smart LiPo's (because my 8S batteries are these and so is my charger), I don't understand enough about the differences between these (apart from price), especially what the 30C, 50C or 100C benefits or negatives would be;5000mAh 6S 22.2V 100C5000mAh 6S 22.2V 50C7000mah 6S 22.2V 30C7000Mah 6S 22.2V Smart G2 30CDon't want to choose something that will fry my setup!Any advice greatly received, thanks.
