The brief reply is that in the case 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 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 a better C score delivers extra vitality, and which means increased 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 capacity to take care of a better and extra constant voltage is what usually generates the excessive efficiency we get pleasure from. That is significantly 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 will let 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 enhance in present permits us to run larger (or extra) motors in your multirotor for elevated period and/or payload-lifting capabilities. The next C discharge score offers us that additional “oomph” we get pleasure from in flight, irrespective of the airframe.
Though a pack with a better C score can usually be charged in much less time as a result of it may tolerate a better present price, 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 a whole cost. Doing this has produced the perfect ends in our expertise; we now have some older packs that also function nicely after
lots of of cost and discharge cycles.
