The brief reply is that in terms of 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 terms 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 total capability. A battery that has the next C score delivers extra power, and meaning larger efficiency. The massive distinction between batteries with totally different C rankings is the truth that the higher-rated batteries undergo much less from voltage drops beneath 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 notably vital when you have got 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 mean you can 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 score offers us that further “oomph” we take pleasure in 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 could tolerate the next present charge, don’t be in a rush; you possibly can 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 ends in our expertise; we’ve got some older packs that also function nicely after
a whole bunch of cost and discharge cycles.
