What has more power 4 batteries of 1.5 volts each or a single battlery of 4.8 volts?

If you connect the four batteries in series, you get 1.5 x 4 = 6 volts total. So the four batteries give more volts.
If the question is which alternative will deliver more power as in watts, that depends on both the batteries and the application. As an example, a 12 V car battery has higher capacity and can deliver far more watts than eight torch batteries in series for the same number of volts.
But as long as the maximum current the application draws is no higher than what the smallest batteries can deliver, the power (watts) will depend only on voltage.

What is the meaning of volts in car batteries?
Voltage is how much power the batteries have. I think....
How many batteries you require to get output of 48 volts?
You need to divide the 48 volts by the voltage produced by a single battery.
How many volts do 3 AA batteries supply?
A single AA battery will produce 1.5 volts. In series the voltage is additive. In parallel the voltage remains the same but the batteries total capacity is increased.
Can you wire two 6 volt batteries together maintaining 6 volts but wire a separate plug off the batteries in such a way as to have a single isolated 12 volt plug?
Yes, series the two batteries to produce 12 volts. Tap off of the two end terminals for the 12 volts. Tap off of the series jumper for the 6 volts of one of the batteries. The two 6 volt batteries can not be paralleled in this connection as they will short out.
How do you convert 120 volts electric fan to 240 volt?
put double power batteries in
Why do some items need 2 batteries?
Generally, it needs twice the voltage supplied by one battery. For example, a 2-cell flashlight using 2 of AA or C or D batteries is combining the voltage of 1.5 volts supplied by each cell to produce a total (average) of 3 volts to power a 3v bulb. The above example assumes the batteries are connected in series, or in line. If two batteries are connected in parallel (that is, head-to-head and tail-to-tail), the combination produces the same voltage as a single battery but can power a load for twice the time as would a single cell.
How do you connect two batteries to work as one?
Type your answer here... To use two batteries as a single power source, you have to connect the positive to the negative and the remaining negative to ground. The remaining positive goes to the red positive cable. The batteries are now in a series circuit. If you use two 6 volt batteries the total voltage is 12 volts. If you use 2 12 volt batteries the total voltage is 24 volts. If you hook the batteries both negative to negative and positive to positive you have made a parallel circuit. Batteries in a parallel circuit cancel each other out. Two 6 volt batteries in parallel have a total voltage of 0 volts. klb
How many volts are there in a single A battery?
The old A batteries used in vacuum tube radios were initially 2 volts but later 1.4 volts became more common. You can find them also in other voltage ratings.
How much volts used in car batteries?

HOW MANY VOLTS ARE IN THE BATTERIES WE HAVE USED?
The small batteries (dry cells) used for many electronic devices usually have approximately 1.5 volts. Car batteries (which have several cells working in series) usually have around 12 volts. Other batteries may have other voltages.
