Battery Size Calculator

Complete the following input data to calculate the required battery size to achieve the desired runtime

Kw Load:   

Inv Eff %:   

Number Of Batt In String:          

Number Of Parallel Batt Strings:

Desired Runtime Minutes:          



Battery Rating =    Watts

Battery Power =    Watts Per Battery

Battery Power =    Watts Per Cell

Battery Current =  Amps



*Battery size calculation assumes 1.67 volts / cell cutoff
*Actual battery performance may vary from calculated values due to condition of the battery, operating temperature, and other factors
