The quick reply is that in the case of flight instances and motor efficiency, the upper a battery’s C score, the extra possible it’s 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 total capability. A battery that has a better C score delivers extra vitality, and meaning greater efficiency. The massive distinction between batteries with totally different C scores is the truth that the higher-rated batteries endure much less from voltage drops underneath load. This skill to take care of a better and extra constant voltage is what usually generates the excessive efficiency we get pleasure from. That is notably vital when you will have 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 improve in present permits us to run greater (or extra) motors in your multirotor for elevated period and/or payload-lifting capabilities. The next C discharge score offers us that further “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 well tolerate a better present charge, don’t be in a rush; you’ll be able to at all times cost it at 1C (one instances the capability), which is able to take about an hour for a whole cost. Doing this has produced the perfect ends in our expertise; we’ve got some older packs that also function properly after
a whole bunch of cost and discharge cycles.
