"Easy ESC" 12v to 24v Kit for "Best Choice" Cars
(sold by "Big Toys Green Country", Amazon and many others)
Doubles Speed & Power
Plug and Play - installs in minutes
Re-uses factory controls for a clean install
Allows adjustment of acceleration rate and speed (from mild to wild)
Optional remote brake stops car
Re-uses factory motors and gearboxes
Factory radio and LEDs function normally
You will also need one additional 12v battery and a 24v charger (both optional add-ons). Two new 12AH SLA batteries recommended.
WHAT IS THIS?
Plug and Play 24v module that replaces the factory 12v circuit board. The factory circuit board can only accept 12v but this module can accept 24v which will double the factory speed. The new module has two turn dial controls which allow adjustment of the acceleration rate and top speed. The factory controls remain the same (foot pedal and shifter), radio and LEDs will still work but RC function will no longer work. Works with 2WD and 4WD cars. The performance dials can be adjusted to have the best balance of performance and stability for each car and environment.
This "Easy ESC" Kit
NO. If the ESC fails the motors will receive full power until the battery is disconnected! The significance of this cannot be overstated
Plug and play, installs in minutes and can be easily and cleanly uninstalled later
Overhaul, new controls
Top Speed and Acceleration Limits
YES - two turn dials for easy on-the-fly adjustments. Mild speed and acceleration settings will prevent the factory motors from failing
No, if controls are abused the motors can fail
Optional remote brake allows the car to be stopped remotely
No. On-demand power draw, cannot be left on. This can prevent permanent battery damage which can cost $50+ to replace
Yes. Batteries that are completely drained typically need to be replaced.
Shifting While in Motion
Motor direction changes suddenly which can break the gears
No. Push the pedal and the car revs up to set speed at set acceleration rate, release the pedal and the softened brake is automatically activated
No Changes. Re-uses factory pedal and shifter for a clean and easy install. Factory accesories parts still function normally.
New controls. Bulky pedals can cramp riders and make controlling the car harder. Factory radio and LEDs are not powered.
Automatic soft brake after releasing throttle pedal
Easy to install, mild settings prevent motor failure, factory radio and LEDs still work. Easy way to increase speed.
No fail safe makes this setup dangerous. Period.
BEFORE YOU BUY:
Check with connector your factory circuit board has. There are three 7-pin types and one 5-pin. If you cannot determine which 5 or 7 pin harness your circuit board has please contact us
Determine what capacity battery the car has from the factory and get the same capacity (AH).
For example if the car came with (two) 7AH in parallel this is the equivalent of (one) 12v 14AH. You can either separate the batteries you have with the kit which would make a 24v @ 7AH, or you can pair the two factory batteries with (one) 12AH to make 24v 12AH. Ideally getting (two) new 12AH batteries is best whenever possible.
Determine where the battery will be stored, either within 12" of the factory module & battery or separately (up to 4' away).
Installation takes just a few minutes. Required tools are just a phillips screwdriver/power driver. The steps are: Charge the factory battery. Unplug the factory circuit board and remove it. Mount the new module in its place (be aware of screws that can protrude through the mounting surface) and connect the new module to the car's harnesses. All connectors are physically unique so it is impossible to make a mistake. Finally connect the battery(ies) and test the car with the wheels off the ground.
FREQUENTLY ASKED QUESTIONS:
(Q) Can I upgrade the factory motors?
(A) NO. Changing the factory motor speed can damage the new motors and ESC. If for example you replace the factory 8,000 rpm motors with 30,000 rpm motors you are quadrupling the theoretical final speed which is like attempting to start your car from a stop in fifth gear and will create a tremendous strain and cause parts to fail.
(Q) Can I continue to use the factory RC function?
(A) NO. Unfortunately the factory remote control function will be lost.
(Q) Can I use a single 12v battery or two in series (24v) with the kit?
(A) YES. The module can accept (1) 12v or (2) 12v batteries. Always make sure batteries are individually fully charged before they are paired and once paired always use a charger with a output voltage that matches the total battery voltage! If you have 24v batteries you cannot use a 12v charger.
(Q)Are instructions included with the kit?
(A) We provide written instructions and provide support via email.
