The brief reply is that on the subject of flight occasions and motor efficiency, the upper a battery’s C score, the extra possible 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 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 potential to take care of the next and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is notably vital when you’ve a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps constantly (10 occasions 2000mAh equals 20 amps). A 20C pack of the identical capability will safely help you draw 40 amps from it constantly. 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, irrespective of the airframe.
Though a pack with the next C score can typically be charged in much less time as a result of it might probably tolerate the next present price, don’t be in a rush; you possibly can at all times cost it at 1C (one occasions the capability), which is able to take about an hour for an entire cost. Doing this has produced the perfect ends in our expertise; we have now some older packs that also function nicely after
a whole bunch of cost and discharge cycles.
