In principle a twelve volt battery (or battery of any voltage) can run a 300 watts load (or any load). However, there are practical problems. As we know, Power = Voltage x Current . Hence, a 300 watts load at 12 V will require a current of 300/12 = 25 A. To carry a 25 A current a conductor of very large cross sectional area will be required. Apart from the practical problem of handling such a thick cable, the cost considerations rule out this option because the cost of such a cable will be much larger than the additional cost of a higher voltage battery. A # 10 copper wire will carry 30 amps.

∙ 13y agoA normal battery is ~80 Amp hours. so a 12 v draw at 25 Amps = 300 W. The battery will last about 80/25 = 3.2 hours. Then it is dead and you cant start the car. If you run it for 1 hour the car might still start. But with an old battery it can be 50% less time.

∙ 15y agoIf the amplifier's supply voltage requires 12 volts then yes. Make sure the wires supplying the voltage are # 12 as the amplifier will be drawing 16.6 amperes. Use an in line fuse of 20 amps.

What is meant by 300Ah battery?
300 ah means that battery can supply 300 am for 1 hr at 12v or 24 v, whichever volt it is producing. for e.g. at 450 Watt load , the current flow=450/24 at 24 volt=18.75am. life of battery will be 300/18.75=16hr and at 12 volt it will have 8hr life only at 450 watt load.
HoW many amp is 300 watts?
As asked, the question cannot be answered. At 1 volt, 300 Watts = 300 Amps. At 10 volts, 300 Watts = 30 Amps. At 100 volts, 300 Watts = 3 Amps. At 120 volts, 300 Watts = 2.5 Amps. At 240 volts, 300 Watts = 1.25 Amps. To calculate the relationship between Amps, Volts and Watts, use the formula: Watts = Amps * volts
How many watts are in 300 volts?
300 watts is not any volts. Watts are how much power is being used regardless of the voltage. For example you could have a 300 watt spot light in a truck running off the 12 volt system in the truck or you could have a 300 watt security light on your house running off of 120 volts.
Never use a halogen light bulb over How many watts?

What charger do you need for a 24 volt battery?
The formula you are looking for is I = W/E. Amps = Watts/Volts. 300/24 = 12.5 amps. A good charger with an output of 15 amps will do the job nicely. The time that it will take to charge the battery will depend on the amp/hrs of the connected battery and the state of discharge that the battery is in when charging starts.

What is rms watts on legacy LA-2889?
It is advertised as a 5,000 watt max amplifier and it is capable of putting out 300 watts rms according to their owners manual but you will never see them advertise it anywhere and that is assuming you are using a 14.4 volt battery which I don't know anyone who has one.
