The brief reply is that in relation to flight instances and motor efficiency, the upper a battery’s C score, the extra seemingly it should make you smile. A 45C pack makes a joke of a 10C pack in relation to 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 large distinction between batteries with completely different C scores is the truth that the higher-rated batteries undergo much less from voltage drops below load. This potential to keep up the next and extra constant voltage is what sometimes 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 constantly (10 instances 2000mAh equals 20 amps). A 20C pack of the identical capability will safely will let you draw 40 amps from it constantly. 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. The next C discharge score provides us that further “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 might probably tolerate the next present price, don’t be in a rush; you possibly can all the time cost it at 1C (one instances the capability), which can take about an hour for a whole cost. Doing this has produced the perfect ends in our expertise; we have now some older packs that also function properly after
lots of of cost and discharge cycles.
