im just wondering

First of all, the power rating you mentioned is quite an imaginary term for a battery. It would be quite impossible to find a battery which could provide 30KW of power.
The batteries are usually 12 volts with different AH (ampere hour), but there are also custom made batteries which could be 36 volt, 48 volt and 60 volt. The most common is 12 volts. Generally, you may not find batteries over 300AH easily, any ratings above 300AH has to be custom made and they become very expensive and very very heavy.
Power rating of normal 12volt 200AH battery = 12 * 200 = 2400 watts
You mentioned 30 KW, which means you will require appx. 13 batteries in parallel connection and you will get 12 volts and 2500 Amperes for an hour
But you can also connect them into series with same power rating, but different voltage. if you connect 13 batteries you may get appx 156 volts and 200AMP for an hour
Time duration increases in both the cases when load is reduced.
Hope this information helps !!

Battey voltage and energy are unrelated. Look up the specs on an old WWII lead-acid battery. 2 V and gobs of kW-hrs. There are also high voltage batteries with little energy.

Zero,
It depends on the circuit without a circuit their is no voltage.
Wattage = power X amps.
So if you had a circuit that could carry one amp then it would have a voltage potential of 30,000
If the circuit can carry 10,000 amps then it would be at a voltage of 3 volts.

Watts is a measure of power. You can't store power. You can only store energy.

10 ohms and 40 watts skill I = sqrt(W/R) = sqrt(4) = 2 amps. subsequently the voltage of 30V drops to 20V whilst resistance is 10 ohms. the drop being 10V, and present day being 2 amps, the inner res is 5 ohms.

You can't store watts. The question makes no sense.

You need a given time, you may have any volts.

i think its incredibly stupid to report people's answers when they tell you you are an idiot, when you actually are an idiot.
