In this Instructable, I'm going to be installing an ESC (electronic speed controller) into our 24volt Grave Digger Power Wheels. If you haven't been following along, I've done a bunch of other requisite modifications to this beastly BPRO. This should be our final upgrade before I go and just fully convert it into an electric go-kart.



Why do I need an ESC? It's the best way to prevent mechanical failure of gears, motors and wiring when you run 24+volts of DC power to a kid's BPRO (battery powered ride on). The ESC provides soft start, variable throttle and soft braking. These are the main features that allow you to go to 24v and beyond without shredding your gearboxes and melting your wires. The stock throttle pedal is just an on/off switch. Larger motors on higher voltages can put out a lot of torque. Applying all that torque instantaneously is a recipe for breaking things. The ESC allows you to softly ramp up your throttle, which not only prevents breakage, but has better acceleration vs stock (because you're not just doing burnouts until the wheels grab, they will start soft, grab and go).



Plus you also can get cool features like remote parental kill switch, backup beeper and easy 12v accessory wiring.



I got my ESC from www.EastCoastPowerUp.com . The 1000w DIY kit is an awesomely fun wiring project (for those that like that sort of thing) and the man running the show there is super helpful and willing to answer any questions you might have. Some of the best customer service I've ever experienced. Can't recommend them enough. (No, I wasn't paid to say that... and Yes, I happily paid full price for the kit. It's an excellent value.)
