The brief reply is that on the subject of flight instances and motor efficiency, the upper a battery’s C ranking, the extra seemingly it should make you smile. A 45C pack makes a joke of a 10C pack on the subject of 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 greater efficiency. The massive distinction between batteries with completely different C rankings is the truth that the higher-rated batteries endure much less from voltage drops beneath load. This skill to keep up the next and extra constant voltage is what usually generates the excessive efficiency we take pleasure in. That is notably necessary when you could 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 mean you can 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 period and/or payload-lifting capabilities. A better C discharge ranking provides us that additional “oomph” we take pleasure in in flight, irrespective of the airframe.
Though a pack with the next C ranking can usually be charged in much less time as a result of it may well tolerate the next present price, don’t be in a rush; you may all the time 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 perfect leads to our expertise; we’ve got some older packs that also function properly after
tons of of cost and discharge cycles.
