This MicroController is used in conjunction with the Okai ES200G scooter Battery Packs. These battery packs require a status/unlock signal to their BLUE (Tx) wire with 9600 Baud serail: 0x3A, 0x13, 0x01, 0x16, 0x79
Then the battery replies with an extensive status report on the GREEN (Rx) wire. We are currently designing a device to display the status report from the battery, but for now we can turn them on and use them to power many 36v devices. The Arduino is pre-Programmed with the following code:
// 0x3A, 0x13, 0x01, 0x16, 0x79
To power your Arduino you have to use a DC-DC that makes the battery packs 42v down to at least 3.6v. We recommend this DC-DC
Here is how the Arduino is programmed.
