ITEM NAME:2-4s 30A Brushless Electric Adjustment, No Plug Required Descriptio n Description Material: plastic Color: picture color Size: 45 * 24 * 11 mm Weight: 0.025 kg Product list :1pcs* 30A brushless current adjustment without plug 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.Battery type: li-xx (lithium battery)/ni-xx (nickel cadmium or nickel hydrogen), the default value is li-xx (lithium battery). Continuous current of 30A, instant 35A, 40A lasts 10 seconds. 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;.
