This is a dune buggy or kart if you will I got for a couple hundred and pulled the slow 110cc motor out and found a 4.5hp 36v golf kart motor from gordo that was rusted and not moving! So I cleaned it up and put some new bearings in it and replaced the brush wires. Then I widened the front end and put better suspension all the way around the buggy. I added some cooling holes and a centrifugal fan to the motor. I got a 225amp 50v controller and opened it up to find there is 11 of the 20 mosfets missing. I ordered them and added the gate resistors and cranked the pot for current limiting and WALA!

RC lipo and most other types of Lithium batteries you MUST know your individual cell voltages while charging and discharging.
Batteries of all kinds need respect they can burn your house down, so don't sleep with them under your bed or any other were you cant afford smoke or fire!
