The C rating on a battery is a reference value to what constant "current" it can put out. Why that is important is the relation to how much power it will output to your motors (that's known as discharging or 'drain' on the battery). It also is reference to how high a rate of charge current the battery can handle (the higher the number, the higher current you can charge the battery at - thus, if you have a varying rate charger, you can fully charge higher C rated batteries faster at the maximum current it can take the charge). The C rating can also be an indication of how much 'punch' or burst it can output to your motors (just make sure your ESCs & motors can handle it, or you'll be burning them out fast for sure). Here's a link that explains about LiPo battery C rating:I’m new to Drones and have my first one on order. A GT2 Crusader which will be here this coming Wednesday. I’m super stoked to start learning. Got two buddies that are serious Drone pilots to help me.
So the 120C rating means??? I’ve got four Turnigy 1300 4S 65C battery’s onntheir way.
