Additional Details

  • Does not include an on/off switch like similar low voltage ESCs for your safety. Use our 14S High Voltage On/Off Switch to power on your electric skateboard setup safely without failure. No need to disconnect batteries overnight.
  • Dual Motor ESC can be created with two single escs. Less chance of failure and Y connectors are included if two (single 12S ESCs) are purchased.
  • Cut Off Voltage feature is designed by total voltage / 4.2v LiPo = X cells. Please make sure to use a full or close to full battery pack with 3.4v cut off.
