The quick reply is that in the case of flight instances and motor efficiency, the upper a battery’s C ranking, the extra seemingly it is going to make you smile. A 45C pack makes a joke of a 10C pack in the case of 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 massive distinction between batteries with completely different C scores is the truth that the higher-rated batteries endure much less from voltage drops underneath load. This capacity 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 constantly (10 instances 2000mAh equals 20 amps). A 20C pack of the identical capability will safely mean you can 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 may ship (in our 2000mAh instance) 60, 90, and 140 amps. This main improve 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 get pleasure from in flight, regardless of the airframe.
Though a pack with the next C ranking can usually be charged in much less time as a result of it will possibly tolerate the next present price, don’t be in a rush; you may all the time cost it at 1C (one instances the capability), which is able to take about an hour for an entire cost. Doing this has produced the very best leads to our expertise; now we have some older packs that also function properly after
a whole bunch of cost and discharge cycles.
