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.
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.
To calculate the wattage produced by a 48-volt battery, you need to know the current (in amperes) it can supply. Once you have the current value, you can use the formula P = V x I, where P is power in watts, V is voltage in volts (48V in this case), and I is current in amperes. So, without knowing the current, we cannot determine the wattage produced by a 48-volt battery.

Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
Assuming 100% efficiency, a 36-volt battery charger would use 36 watts per hour to charge the battery fully. However, it's important to consider that chargers are not 100% efficient and may draw slightly more power from the wall.
It would just last longer between charges.
49v2 + 9 - 42v = 49v2 - 21v - 21v + 9 = 7v(7v - 3) - 3(7v - 3) = (7v - 3)2
123mb
7v -14 = -7
It can be simplified to: -7v-1096
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.
-- 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.

Unfortunately, heaters can put out over 1,000 Watts, which is far too much for any battery assembly to power.
