The brief reply is that in relation to flight occasions and motor efficiency, the upper a battery’s C ranking, the extra probably it’ll make you smile. A 45C pack makes a joke of a 10C pack in relation 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 general capability. A battery that has the next C ranking delivers extra power, and which means greater efficiency. The large distinction between batteries with totally different C scores is the truth that the higher-rated batteries undergo much less from voltage drops beneath load. This skill to keep up the next and extra constant voltage is what usually generates the excessive efficiency we get pleasure from. That is notably necessary when you may 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 will let 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 ranking offers us that further “oomph” we get pleasure from in flight, regardless 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 at all times 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 leads to our expertise; we now have some older packs that also function effectively after
tons of of cost and discharge cycles.
