lithium vs lead acid for gokarts Answered
For electric go karts, which one is better (for the money)? Lead acid is by far much much cheaper, but it is much much heavier. With a heavier battery you need a stronger frame, which weighs even more. With all of this weight you need an even stronger motor to push it all. With lithium you can build a lighter, cheaper frame, and power it with a weaker and cheaper motor and still obtain the same speeds. Lead Acid batteries take up about 1/3 the weight of a gokart with rider (1/3 being the driver, and the other third being chasis and motor and such). Reducing the weight by about a third (honestly, lithium, batteries weigh like nothing) could have huge performance improvements. So, does spending more money on batteries, and saving money on chasis and motor equal out to spending less on batteries and more on chasis and motor?
