The brief reply is that in relation to flight occasions and motor efficiency, the upper a battery’s C score, the extra probably it should 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 total capability. A battery that has the next C score delivers extra vitality, and meaning greater efficiency. The massive distinction between batteries with totally different C rankings is the truth that the higher-rated batteries endure much less from voltage drops underneath load. This capability to take care of the next and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is significantly essential when you’ve gotten 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 let 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 improve in present permits us to run larger (or extra) motors in your multirotor for elevated length and/or payload-lifting capabilities. A better C discharge score offers 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 will probably tolerate the next present charge, don’t be in a rush; you possibly can all the time cost it at 1C (one occasions the capability), which is able to take about an hour for an entire cost. Doing this has produced one of the best ends in our expertise; we have now some older packs that also function nicely after
lots of of cost and discharge cycles.
