The brief reply is that on the subject of flight instances and motor efficiency, the upper a battery’s C score, the extra possible it is going to 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 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 completely different C rankings is the truth that the higher-rated batteries endure much less from voltage drops beneath load. This skill to keep up the next and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. 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 assist you to 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 length and/or payload-lifting capabilities. The next C discharge score provides 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 possibly tolerate the next present fee, don’t be in a rush; you possibly can all the time cost it at 1C (one instances the capability), which can take about an hour for an entire cost. Doing this has produced the perfect leads to our expertise; we’ve got some older packs that also function effectively after
a whole bunch of cost and discharge cycles.
