# What do you guys think

If i run 12 12v batteries in series to get 144v and the batteries are 100 ah. Does that mean i will only have a total of 100ah at 144v to use? If i lowered my voltage and and raised my AH by running some of the batteries in parralel, wont my range still be the same since its a lower voltage and its going to pull more amps to get the same rpm out of the motor? Im a bit confused.

range is based on Wh/mileâ€¦

watt hours is volts times amps, 144V and 100Ah is 14,400Wh.

If you lower the voltage and run 200Ah and 72V, its still 14,400â€¦ The controller does the power conversionâ€¦ so it can run the motor at 72V and give it 200A, but only draw 100A out of the batteries at 144V.

Basically what im wanting to i know is if i will have the same range if i have 100v and 50ah would i have the same range as if i had 50v and 100ah considering Watts=volts.amps and Watt hours equalls my range.

essentially yesâ€¦

but if you draw high amps (lets say 200A) out of the 50Ah system, the batteries will NOT like itâ€¦ but the 100Ah batteries will be less effected. Its called the peukert effect. If you draw higher currents, it decreases the total Watt Hours of the battery.
