![]() So a 100Ah LiFePO4 battery will likely have a recommended max charge rate of 50 amps. ![]() For instance, most lithium iron phosphate batteries have recommended max charge rates in amps equal to 50% of their capacity in amp hours. 9.90 is 30% of 33.īatteries have recommended max charge and discharge rates based on their capacity in amp hours. So this 33Ah lead acid battery I own has recommended "initial current" of less than 9.90 amps. For example, the rates in amps for most lead acid batteries are 30% of amp hour capacity. Pretty easy! Why Convert Kilowatt Hours to Amp Hours? Battery charge and discharge rates are based on their capacity in amp hours. So, in this example, your generator's battery has a capacity of 50 amp hours. Knowing these two numbers, you can now calculate your battery capacity in amp hours. You look through the product manual and find that the battery voltage is 43.2 volts. Let's say you own a solar generator with a battery capacity of 2.16 kilowatt hours. To convert kilowatt hours to amp hours, divide kilowatt hours by volts, then multiply by 1,000.Ĭonversion formula: amp hours = kilowatt hours ÷ volts × 1000Ībbreviated: Ah = kWh ÷ V × 1000 Example: How to Calculate Amp Hours of a Battery ![]() How to Convert Kilowatt Hours to Amp Hours (kWh to Ah) Note: Don't see the values you're looking for in this chart?
