Scooter batteries unlocking module (ex. OKAI ES200G) – pre-programmed micro controller with power supply.

Pre soldered tool contains:

  1. Micro controller (8/16MHz) – pre-programmed to unlock battery
  2. Power converter (72/43/36V to 12/7/5V) – so step down from battery voltage to module voltage
  3. (optional, extra fee) plastic case with ventilated lid

What this tool is about

Battery pack require a status/unlock signal to their BLUE (Tx) wire – this tool (module) will provide right signal to unlock your battery – this is tested on OKAI ES200G battery but many vendors (DOTT, BIRD) use similar or the same one.

For now it’s only one way communication, firmware updates are coming soon to also read battery status (voltage and capacity). Firmware will be available through your account panel on scooter-unlock. This module has “open” status which means micro-USB port is open for updates and tool is not sealed to provide further soldering abilities for your battery.

Shipping to USA, EU and many other countries.
