Working on my first EV conversion so I'm learning some expensive lessons. I got a 96v 100ah LiFePO4 battery that unfortunately can only put out 100 amps continuously. I have a 24kw DC motor that should be able to handle 500 amps. The car only goes about 25mph. I think it's because the battery can't supply more current. I can get a battery that will put out 300 amps, but before I drop another 3k on a new battery pack I'm wondering if there is a way to verify that increasing current will actually make the car go faster. If this were a smaller project I would connect up a wired Power Supply to verify but I don't have a 96vdc 300amp Power Supply laying around the house.
Any suggestions?
