The quick reply is that relating to flight occasions and motor efficiency, the upper a battery’s C ranking, the extra doubtless it should make you smile. A 45C pack makes a joke of a 10C pack relating to energy supply. The C ranking 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 ranking delivers extra power, and meaning greater 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 underneath load. This capacity 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 a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps constantly (10 occasions 2000mAh equals 20 amps). A 20C pack of the identical capability will safely permit you to 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. A better C discharge ranking offers us that additional “oomph” we take pleasure in in flight, irrespective of the airframe.
Though a pack with the next C ranking can typically be charged in much less time as a result of it may possibly tolerate the next present fee, don’t be in a rush; you possibly can all the time cost it at 1C (one occasions the capability), which is able to take about an hour for a whole cost. Doing this has produced the very best leads to our expertise; we have now some older packs that also function properly after
tons of of cost and discharge cycles.
