It summarizes the experience of how to choose battery for quadcopter after analyzes quadcopter parameters by moreexperienced pilots.
Step 1, Choose the longest flight time battery for quadcopter
I believe that you have already know the Average Amp Draw of your quadcopter, if not you have to work out it. Then make a battery calculator to get quadcopter flight times through formula.
How to do it ? you should read my this post: How to calculate quadcopter flight times , It’s much important to choose battery for quadcopter
Step 2, Consider the c-racing
To Choose a suitable lipo battery for your quadcopter, you have to compare target c-rating and battery c-racing.In short, my principle is that battery c-racing is greater than target c-rating but not too higher.
- My target C-rating target calculations are based on an estimated draw at full power of motors and Props.
- Battery c-racing are based on standard formula (Discharge Rating =Ah*C-rating ).
For example, I have a FPV racing 180 mini quad, my target c-rating is 65A from Cobra 2204 2300kv motors and HQ 4x4x3 props.
I choose gens ace 1050mAh 75C lipo pack.battery c-racing is 78.75A(=1.05Ah * 75C). It’s great for my mini quad.
Step 3, Consider the price
If price were not a consideration, you should choose the lipo battery which provided the longest flight time for quadcopter. This is also my selection criteria.
When considering the price, you have to make a value which is capacity per dollar ( capacity / price), The max one is best for you.
For example, There are two battery A lipo battery 4s 75c 1500mAh is $38 and B lipo battery 4s 75c 1800mAh is $45. A capacity per dollar is 39.47(=1500/38) and B capacity per dollar is 40 (=1800/45), so i will choose B lipo battery.
How to choose battery for quadcopter? It’s a hard job, Through the above analysis, I hope you can resolve it and enjoy your flight times.
