Peukert’s Equation and Battery Capacity
Battery capacity planning seems simple, but can be a bit tricky. If you have a 100 amp hour battery, you might think you can draw 100 amps for 1 hour, 50 amps for 2 hours, and 25 amps for 4 hours (or even 200 amps for .5 hours). Well it doesn’t quite work out that way. The reason was formulated by a scientist by the name of Peukert, and basically says the faster the rate of discharge, the lower the usable ah capacity you have. The slower the rate of discharge, the higher the usable ah capacity. Read more and try out our new calculator at:
