OWIE Chip - ESP8266

This chip is commonly used to bypass the Controller/BMS pairing done by FM. This also allows for installing larger capacity batteries in the XR and Pint. 

You can buy these same chips off Amazon, but I pre-flash these with the OWIE 1.4.3 firmware before shipping.

This chip can also be used with VESC™ conversions when utilizing the stock FM bms as charge only. Please see PEV.dev for details.
