The brief reply is that on the subject of flight instances and motor efficiency, the upper a battery’s C score, the extra probably it would make you smile. A 45C pack makes a joke of a 10C pack on the subject of energy supply. The C score 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 score delivers extra power, and meaning larger efficiency. The large distinction between batteries with completely different C rankings is the truth that the higher-rated batteries undergo much less from voltage drops beneath load. This capability to keep up the next and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is significantly necessary when you might have a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps repeatedly (10 instances 2000mAh equals 20 amps). A 20C pack of the identical capability will safely 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 can ship (in our 2000mAh instance) 60, 90, and 140 amps. This main enhance in present permits us to run larger (or extra) motors in your multirotor for elevated period and/or payload-lifting capabilities. A better C discharge score offers us that additional “oomph” we get pleasure from in flight, regardless of the airframe.
Though a pack with the next C score can usually be charged in much less time as a result of it may well tolerate the next present price, don’t be in a rush; you’ll be able to 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 one of the best leads to our expertise; we have now some older packs that also function nicely after
a whole bunch of cost and discharge cycles.
