The brief reply is that in relation to flight occasions and motor efficiency, the upper a battery’s C ranking, the extra probably it would make you smile. A 45C pack makes a joke of a 10C pack in relation to energy supply. The C ranking for a LiPo battery, fairly merely, refers back to the capability of power the battery can safely discharge, represented as a a number of of its general capability. A battery that has a better C ranking delivers extra power, and meaning larger efficiency. The large distinction between batteries with totally different C scores is the truth that the higher-rated batteries undergo much less from voltage drops below load. This means to keep up a better and extra constant voltage is what sometimes generates the excessive efficiency we get pleasure from. That is significantly 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 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 improve 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 ranking provides us that further “oomph” we get pleasure from in flight, irrespective of the airframe.
Though a pack with a better C ranking can typically be charged in much less time as a result of it could actually tolerate a better 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 a whole cost. Doing this has produced the most effective leads to our expertise; we now have some older packs that also function effectively after
lots of of cost and discharge cycles.
