The brief reply is that in the case of 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 in the case 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 general capability. A battery that has the next C score delivers extra vitality, and meaning increased efficiency. The massive distinction between batteries with totally different C rankings is the truth that the higher-rated batteries undergo much less from voltage drops below load. This capability to take care of the next and extra constant voltage is what usually generates the excessive efficiency we get pleasure from. That is notably vital when you will have a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps constantly (10 instances 2000mAh equals 20 amps). A 20C pack of the identical capability will safely can 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 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. 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 usually be charged in much less time as a result of it may possibly tolerate the next present charge, don’t be in a rush; you’ll be able to 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 most effective leads to our expertise; we’ve some older packs that also function effectively after
a whole bunch of cost and discharge cycles.
