The brief reply is that with regards to flight instances and motor efficiency, the upper a battery’s C score, the extra seemingly it is going to make you smile. A 45C pack makes a joke of a 10C pack with regards 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 the next C score delivers extra vitality, and meaning larger efficiency. The large distinction between batteries with totally different C rankings is the truth that the higher-rated batteries endure much less from voltage drops beneath load. This means to take care of the next and extra constant voltage is what usually generates the excessive efficiency we get pleasure from. That is notably necessary 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 help 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 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 score provides us that further “oomph” we get pleasure from in flight, regardless of the airframe.
Though a pack with the next C score can typically 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’ll be able to at all times cost it at 1C (one instances the capability), which can take about an hour for a whole cost. Doing this has produced the most effective leads to our expertise; we’ve some older packs that also function properly after
a whole bunch of cost and discharge cycles.
