The brief reply is that relating to flight instances and motor efficiency, the upper a battery’s C score, the extra doubtless it’ll make you smile. A 45C pack makes a joke of a 10C pack relating to energy supply. The C score for a LiPo battery, fairly merely, refers back to the capability of vitality the battery can safely discharge, represented as a a number of of its total capability. A battery that has a better C score delivers extra vitality, and which means greater efficiency. The large 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 a better and extra constant voltage is what sometimes generates the excessive efficiency we take pleasure in. That is notably essential when you’ve gotten 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 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 period and/or payload-lifting capabilities. A better C discharge score provides us that additional “oomph” we take pleasure in in flight, irrespective of the airframe.
Though a pack with a better C score can typically be charged in much less time as a result of it might probably tolerate a better present charge, don’t be in a rush; you’ll be able to all the time cost it at 1C (one instances the capability), which can take about an hour for a whole cost. Doing this has produced the very best ends in our expertise; we’ve some older packs that also function nicely after
lots of of cost and discharge cycles.
