  • The current are always stable at <11 Amps in any voltages between 7.4v to 12.5v. Low and stable Amps means it drains less battery and the lifespan of the components could last longer.

  • The S.D.U. chipset that used in eSilver Edge Gear Box has a unique function that stop the gearbox from further damage if electric current is too high. Simply to say, electric current / Ampere will increase if there is a malfunction inside the gearbox.
  • For instant, bad motor, damaged gears or short circuit. When our S.D.U. detected more than 5 trigger presses in exceed Amps, the whole gearbox will shut down to prevent further damage.
  • User has to disconnect and then reconnect the power supply to reboot the gearbox, we strongly recommended user to check the internal immediately if mal-function happened.
