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 serial: 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:

void setup() {
void loop() {
// 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:
