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

The wattage of a 18650 battery can be calculated using the formula: Watts = Volts × Amperes (Ah). A standard 18650 battery has a nominal voltage of 3.7 volts, and its capacity typically ranges from 1800mAh to 3500mAh. For example, a 3000mAh (or 3Ah) battery would provide approximately 11.1 watts (3.7V × 3Ah = 11.1W). Therefore, the wattage varies depending on the specific capacity of the battery.
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

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.
how much energy it draws from your outlet or car battery.
45 Watts
Unfortunately, heaters can put out over 1,000 Watts, which is far too much for any battery assembly to power.
v * 7v > 637*v^2 > 63 v^2 > 9 v < -3 or v > 3.
