The quick reply is that in relation to flight occasions and motor efficiency, the upper a battery’s C ranking, the extra possible 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 vitality the battery can safely discharge, represented as a a number of of its general capability. A battery that has the next C ranking delivers extra vitality, and which means larger efficiency. The large distinction between batteries with completely different C rankings is the truth that the higher-rated batteries endure much less from voltage drops below load. This skill to keep up the next and extra constant voltage is what usually generates the excessive efficiency we get pleasure from. That is notably essential when you could have a number of motors turning a number of rotors.
A 2000mAh pack will safely ship 20 amps repeatedly (10 occasions 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 can ship (in our 2000mAh instance) 60, 90, and 140 amps. This main improve 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 ranking provides us that further “oomph” we get pleasure from in flight, regardless of the airframe.
Though a pack with the next C ranking can typically be charged in much less time as a result of it could actually tolerate the next present fee, don’t be in a rush; you’ll be able to all the time cost it at 1C (one occasions the capability), which can take about an hour for an entire cost. Doing this has produced the most effective leads to our expertise; we’ve got some older packs that also function properly after
tons of of cost and discharge cycles.
