The brief reply is that in terms of flight occasions and motor efficiency, the upper a battery’s C score, the extra doubtless it’s going to make you smile. A 45C pack makes a joke of a 10C pack in terms 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 total capability. A battery that has the next C score delivers extra power, and meaning larger efficiency. The large distinction between batteries with completely different C scores is the truth that the higher-rated batteries undergo much less from voltage drops beneath load. This capability to take care of the next and extra constant voltage is what usually generates the excessive efficiency we take pleasure in. That is significantly necessary when you could have 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 can 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 period and/or payload-lifting capabilities. A better C discharge score offers us that additional “oomph” we take pleasure in in flight, irrespective of the airframe.
Though a pack with the next C score can typically be charged in much less time as a result of it could tolerate the next present charge, don’t be in a rush; you’ll be able to at all times cost it at 1C (one occasions the capability), which is able to take about an hour for a whole cost. Doing this has produced one of the best ends in our expertise; we’ve some older packs that also function effectively after
lots of of cost and discharge cycles.
