RE: LiPo C Rating
Only if you decide to discharge it at 25C. That's the maximum discharge rate. The harder you push the motor, the more current it will draw. If you exceed 25C, for instance, (that's 25 times the battery capacity.. 1300 X 25= 32500 miliamps or 32.5 amps. Since the battery pack is not a 32 amp pack, well, it will not last very long at 25C. Over 25C and you will damage that battery pack.
Also, be careful where you charge those LiPo packs. Don't do indoors or in your car. Make sure you are outside and in the open. If it does catch fire, it can be pretty spectacular.
