What''s the maximum voltage battery that I can use with the bafang ultra motor with its stock controller? I was thinking of using a 72 volt battery but would use a 52 volt battery instead if that''s the limitation of the controller. Thanks in advance.
Free Quote9 volts is at 25 mA, is 25mA the max current out of a 9 volt battery? No, 25mA is the safe current for maximum efficiency of the battery. 1.5 volts is 4.0mA, is 4.0mA the max current out of a 1.5 volt battery? No, 4mA is the safe current for maximum efficiency of the battery. Why are they testing a 9 volt batterys current output at 25ma?

Mastervolt Lithium Ion batteries can be subjected to much higher charge currents. However, to maximise the lifespan of the Lithium Ion battery, Mastervolt recommends a maximum charging current of 30 % of the capacity. For a 180 Ah battery, for instance, this means a maximum charge current of 60 amperes.
If you "forget about" internal resistance, then the maximum current is infinite. An "ideal" component, non-existent in the real world, can provide mathematically "pure" infinite or zero amounts of resistance, voltage, current, and all the rest. Different battery compositions will have different amounts of real-world "impure" limitations.
So, yes. Batteries have a max current drain (given by design and physical/chemical limitations) and yes the storage rating (being Ah, Wh or Joules) changes depending on battery design and load applied, and yes Wh is a better way to compare batteries because it takes voltage in account.
Note that the highest discharge current that is mentioned is 1000 mA = 1 A. That does not mean you cannot discharge with 2 A but realize that the battery's capacity will be less at such a high current. You will get less energy out of the battery compared to a more realistic discharge current of for example 100 mA.
It can supply 1.5 V, but I don't see any information about the current (in A) or the power (in W). Where can I find this information? You should look in the datasheet of that AA battery and check the discharge curves. That gives you an indication. Note that the highest discharge current that is mentioned is 1000 mA = 1 A.
