Question about batteries for an electric cart project

[QUOTE="jim hardy, post: 5473266, member: 327872"] What is the nature of your small DC motor ? As Tom.G points out there's more than one way to design them. For high torque loads like vehicles one often chooses a "Series Wound" DC motor. Tom also pointed out there's a voltage vs speed characteristic, You might get fancy and start the cart with batteries in parallel for high current hence torque, then once rolling switch them to series for higher voltage hence speed. Diesel-Electric railway locomotives of the 1960's did something similar with their traction motors. [/QUOTE]
