The quick reply is that in terms of flight occasions and motor efficiency, the upper a battery’s C score, the extra doubtless it should 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 vitality 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 vitality, and meaning increased efficiency. The massive distinction between batteries with totally different C scores is the truth that the higher-rated batteries undergo much less from voltage drops below load. This skill to keep up the next and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is significantly vital when you’ve got 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 assist you to 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 can 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 provides us that further “oomph” we get pleasure from in flight, irrespective 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 price, don’t be in a rush; you’ll be able to all the time cost it at 1C (one occasions the capability), which can 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 nicely after
lots of of cost and discharge cycles.
