# How do I supply power to two 18v 2.4 amp motors?

Any thoughts on where I can get a cheapo 18V 5 amp (sub $10, as that is the remaining budget). Otherwise, I will just go for a 12V and hope it is fast enough. • That's the maximum voltage, but you can also use 12V. I'd use a 12V golf cart battery. – Samuel Jan 29 '15 at 23:11 • You only need 18 volts at 2.4 amps if you want to develop maximum torque. And be advised that if your load is such that you're pulling maximum voltage and current, the motor will overheat very quickly. – WhatRoughBeast Jan 29 '15 at 23:47 • Search for "universal laptop power supply". Perhaps not sub$10, but very close. If you get a \$12 one, don't expect the greatest of quality though. – rioraxe Jan 30 '15 at 21:49
