I would like to test max discharge rates for 1S (200 mAh) LiPo's. But I can see three ways of doing it:
Using a charger, discharge at highest rate and see how high the battery goes.
Using a resistor (0.25 Ohm) and measuring the voltage and amperage. (0.25 Ohm would generate 17.4 amps, which is a bit higher than the maximum expected amperage).
Using a motor and normal load, and measuring voltage and amperage.
What are the differences between these methods? Will they all expose the max discharge rate?
I would like to use method #1 since it is the simplest.
Any relevant links or references would be appreciated.
EDIT: From the comments I see that we need a distinction between burst and sustained discharge rates. For my use case, I am most interested in the burst rate.
Perhaps a good approach would be to connect it to a 0.25 Ohm resistor for 5 sec and measure the result...?
