The brief reply is that in the case of flight occasions and motor efficiency, the upper a battery’s C score, the extra probably it is going to make you smile. A 45C pack makes a joke of a 10C pack in the case of energy supply. The C score for a LiPo battery, fairly merely, refers back to the capability of power the battery can safely discharge, represented as a a number of of its general capability. A battery that has the next C score delivers extra power, and which means greater efficiency. The massive distinction between batteries with completely different C rankings is the truth that the higher-rated batteries undergo much less from voltage drops beneath load. This capability to keep up the next and extra constant voltage is what usually generates the excessive efficiency we take pleasure in. That is significantly vital when you’ve gotten a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps repeatedly (10 occasions 2000mAh equals 20 amps). A 20C pack of the identical capability will safely help you draw 40 amps from it repeatedly. That’s the identical capability and twice the amp draw. There are battery packs on the market rated at 30C, 45C, and even 70C that may ship (in our 2000mAh instance) 60, 90, and 140 amps. This main enhance in present permits us to run greater (or extra) motors in your multirotor for elevated length and/or payload-lifting capabilities. A better C discharge score offers us that additional “oomph” we take pleasure in in flight, regardless of the airframe.
Though a pack with the next C score can usually be charged in much less time as a result of it could tolerate the next present fee, don’t be in a rush; you possibly can at all times cost it at 1C (one occasions the capability), which can take about an hour for an entire cost. Doing this has produced the most effective ends in our expertise; we’ve some older packs that also function nicely after
lots of of cost and discharge cycles.
