ITEM NAME:2-4S 30A Brushless Electric Adjustment Welded T Plug Glass Fiber ELO Descriptio n Description: Material: glass fiber Color: picture color Size: 45 * 24 * 11 mm  Wire 10 cm long Weight: 0.025 kg Product features: 1. Safe power on function: no matter the throttle rocker is in any position, it will not immediately start the motor when the power is switched on, so as to avoid personal injury; 2. Throttle stroke adjustment function: adapt to different remote control oil Door stroke difference, improve the linearity of throttle response, with smooth, exquisite speed feel and first-class speed linear; 3. Program setting items: Battery type: li-xx (lithium battery)/ni-xx (nickel cadmium or nickel hydrogen), the default value is li-xx (lithium battery). Low voltage protection mode: reduce power/turn off output, default value is reduced power. Low voltage protection threshold: low/medium/high, the default value is medium cut-off voltage. When li-xx battery is set, the number of lithium batteries will be automatically judged. At low/medium/high.The output MOSFET power tube is equipped with independent radiator fin to reduce the temperature rise of devices and improve the system's high current working ability;. Weight: 0.025 kg. Material: glass fiber.
