You can always opt to do the math yourself. 1- Converter battery ah into watt-hours (Wh). Frequent Start, 14-20 Wh/km (22-33 Wh/mile), For a 48V ebike that we want a minimum of 30 km riding range. Hence, the final version of the battery capacity formula looks like this: Let's assume you want to find out the capacity of your battery, knowing its voltage and the energy stored in it. How Long Will A 100Ah Battery Run A Tv? I hope this short guide was helpful to you, if you have any queries Contact us do drop a comment below. A lot of datasheets will give you a Power Dissipated value Pd in watts.Power calculation formula. With this offering, GreenWorks includes the previously stated 60V battery and charger. To do this, you have to divide watt-hours by voltage (12V for batteries). Web18650 Battery Pack Calculator; 18650 Battery Cell Manufacturing Process; Lithium Battery Design Pricing Basics; All Things You Need to Know About 21700 Battery; what will happen if Watt/Hour(Wh in short) are involved? When voltage and current are known use P = VI to calculate the value of the power. All Rights Reserved. 1200/400 = 3 3 + 30% = 3.9 peak sun hours. You could express its capacity in kilowatt hours by dividing 396 by 1000 (396 1000 = 0.396). Thats because an 800 W air conditioner on 240V requires fewer amps than an air conditioner on 120V. C-rate is used to describe how fast a battery charges and discharges. Since watts = amps * volts divide the watt hours by the voltage of the battery to get amp-hours of battery storage Amp-hours (at 12 volts) = watt-hours / 12 volts = 1470 / 12 = 122.5 amp-hours. You will need a bit bigger battery for a 2,500-watt motor; 80 amp or 100 amp battery. Similarly, How do I calculate how long a battery will last?
