Features: Battery type: Li-xx (lithium battery) / Ni-xx (nickel cadmium or nickel hydride), the default value is Li-xx (lithium battery). Low voltage for protection mode: Reduce power / turn off the output, the default is to reduce power. Low voltage for protection threshold: low / medium / high, the default is the medium cutoff voltage. When the Li-xx battery is set, the number of lithium batteries is automatically determined. The cutoff voltage of each battery in the for case of low/medium/high is: 2.6V, 2.85V, 3.1V. Plug specification: for T plug Extreme use: Continuous current 30A, instant 35A, 40A for 10 seconds. Dimensions / weight(Approx.): 45*24*11(mm), 25g (including line) Voltage range: 4V-16V Number of batteries: 2-4Lipo (4Lipo does not allow BEC output) BEC output: 2A continuous, (instantaneous 3A) 2LIPO 4-5 Miniature steering engine 3LIPO 3-4 Mini steering engine Setting method 1. Turn on the transmitter and push the throttle to the highest (FUTABA series transmitters need to use the throttle channel to select REV). 2. Connect the receiver and motor. 3. Turn on the ESC power supply. If the transmitter is normal, the following sounds are available: (If the sound is a long "beep" sound after the end of the sound, there is no more sound, then check the transmitter throttle channel reverse setting.) B B stands for LIPO automatic protection BB BB stands for NIMH /NICD automatic protection BBB BBB stands for brake selection Package list: 1x 30A ESC for T plug
