Hey, can anyone help me
What is the power consumption when battery capacity is 100Ah and it works for 20 minutes?


Thanx

If there is no voltage there is no power.
If you don't tell me the voltage, I can't calculate the power.

If 100 AH is gone in 20 minutes, that's 300 amps. Still, with no voltage, there is no power.

Also you can buy it new at 100 Ah but it will degrade over time, and you probably aren't discharging it completely, and depending on how you are discharging it power may or may not be constant over the 20 minute time period. It's going to be very hard to accurately figure out power based on Ah and voltage when really it's very easy if you measure current and voltage.
