Hi Caleb, nice setup. So, you can calculate wattage by multiplying amps and volts. In your case, this is: 40A × 60V = 2,400W. So, this battery can power a 2,400-watt motor for 1 hour. You will need a bit bigger battery for a 2,500 …
As we have seen, this 3-phase power formula calculates how many kW of electric power will a motor have given its current: P (kW) = (I (Amps) × V (Volts) × PF × 1.732) ÷ 1,000. To figure out how many amps does a motor with certain kW power have, we have to rearrange this equation a bit. We get the 3-phase current formula like this:

Online calculator for determining the horsepwer of a motor in relationship to its Watts for electric scooters and bikes.
Let''s say that this is a battery with 7Ahr capacity and that you want to draw 14A. You''ll have to observe the 2C curve (2C means to discharge at 7Ahr*2/h=14A). You''ll note that this battery will drop to 9.5V-10V after about 15mins. Of-course this is only true for a fresh from the shelf battery kept at 25 deg.Celsius.
How Many Watts Does A Car Battery Have? A car battery is rated at 12 volts and is usually charged at a rate of 13.8 volts to 14.3 volts. These batteries range between 40Ah to 110Ah while the alternator can charge the battery at a rate of 45amps to 200amps. ... The number of watts needed to start the car engine will mostly depend on the power ...

Our watt hour calculator allows you to use electric charge in milliamp or amp hours and voltage in volts to calculate the energy in watt-hours or joules.Amp hours – the shortened name of ampere-hour – indicates how much charge can flow through a battery per one hour.More specifically, it is an electric charge in a battery that enables 1 ampere of current to …
So now, instead of the motor pulling 300 watts, with 90 watts going to heat, we are now pulling 399.3 watts of power into the motor with 159.4 watts of it going up as heat. This leaves 239.9 watts to spin the prop and yields an efficiency of 239.9/399.3 which is 60.08%.

*We are considering a 15ah lead-acid battery against a 9ah Li-Ion battery here because the usable capacity (in typical high-amperage use on an E-Bike - see Peukert''s Law) of the 15ah lead is only about 9ah (66%) - note that they have the same range*. As you can see there is a lot to consider if you really want to delve deep into lithium battery packs that are made to power …
Watt-hours means a way to measure the battery''s energy storage and discharge capability. It also indicates how much power can be drawn from the battery in one hour. Watt-hours are calculated by multiplying volts times amps. For example, if your voltage with an average amp output of 12 volts = 144 (or about 130). Thus, your battery can produce ...
Hi Caleb, nice setup. So, you can calculate wattage by multiplying amps and volts. In your case, this is: 40A × 60V = 2,400W. So, this battery can power a 2,400-watt motor for 1 hour. You will need a bit bigger battery for a 2,500-watt motor; 80 amp or 100 amp battery. Ah are basically just amps; so your battery has 40 Ah.
1. do you think with the e-kit and battery power can push me up the hill ? 2. if the watts from my battery is 1344watts but the e-kit is 1000watts, will that mess it up or damage it? 3. the battery fully charged, can it take me to school and back …
Motor nameplates generally will show starting watts, some as high as nine times the running wattage. Check the nameplate to be sure. Be certain to use the starting watts when figuring the correct electrical load requirements. If you don''t have enough power to start you won''t have enough to run. Motor load requirements are listed below:
So I have to choose a 12V, 3A = 12 * 3= 36W power supply to run the motor.This is because DC power supply can supply continous 3A current without any disturbance. Now I wanted to run same motor on battery. I would like to know how much power should be supplied by the battery to run the motor theoretically.
A 100Ah battery can run a 1,200-watt device for 1 h (this is not specified in the chart, you can calculate it). A 100Ah battery can run a 600-watt device for 2 h. A 100Ah battery can run a 300-watt device for 4 h. A 100Ah battery can run a 150-watt device for 8 h.
