The brief reply is that in relation to flight instances and motor efficiency, the upper a battery’s C score, the extra probably it’s going to make you smile. A 45C pack makes a joke of a 10C pack in relation 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 general 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 undergo much less from voltage drops underneath load. This capacity to take care of the next and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is significantly vital when you could have 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 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. The next 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 might probably tolerate the next present price, don’t be in a rush; you may at all times 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 leads to our expertise; we have now some older packs that also function properly after
lots of of cost and discharge cycles.
