Electric power = Volts X Amps,
so 7 vols at 1 Amp will produce 7 watts
7 volts at 5 amps will produce 35 watts
7 volts at 15 amps will produce 105 watts and so on.
Technically, there is not enough information (just volts) to answer your question but if you know the Amps, you can now figure the answer yourself.
There are zero watts in a 7 volt battery. Watts are the product of amps x volts. The amperage of the load connected tot he battery has to be stated. Batteries are usually rated in amp hours.
Watts are made up of Voltage X Amperage draw. So to answer I also need to know amperage draw.
With out knowing two of three components of the equasion this question can not be answered
There could be millions.
Remember that watts are voltage x current(amps) The number of watts you can get from a 48V battery will depend on how many amps the battery can deliver and how much the load can draw.
Watts are the product of amps times volts. The amperage in a circuit is governed by the resistance of the load. A battery just supplies the potential as voltage, the load determines how much current is going to be drawn out of the battery. Batteries are rated in amp/hours. This means how long can a battery maintain a specific amperage over a period of time.

Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
A small battery AM or FM radio uses as little as 3 v at 10 mA, that is 0.03 Watts. A typical DAB radio might used 6 v at 250 mA, which is 1.5 Watts, or 40-50 times as much.

It would just last longer between charges.
49v2 + 9 - 42v = 49v2 - 21v - 21v + 9 = 7v(7v - 3) - 3(7v - 3) = (7v - 3)2
7v -14 = -7

You can't charge the battery with those 245 watts unless they are being 'pumped into' the battery at a higher voltage than the battery puts out. If you can exceed the voltage of the battery, that 245 watts will definitely charge a battery.
It can be simplified to: -7v-1096
-- If the 3 Amp is being drawn from a battery,then the battery is supplying3 x (Voltage of the battery) watts.-- If the 3 Amp is flowing through a resistor,then the resistor is dissipating9 x (Resistance of the resistor) watts.
how much energy it draws from your outlet or car battery.
Unfortunately, heaters can put out over 1,000 Watts, which is far too much for any battery assembly to power.
