Check the 4 pin data cable and confirm it is firmly in place. | |||
If the cable is fine, check for the blinking blue or red led on the top of the battery and make sure that it is blinking. | |||
If it is not, plug in the battery and attempt to charge it. | |||
If the charger is blinking red briefly and green most of the time, leave it plugged in for a few hours until the battery is able to charge to 100%. | |||
If the charger light is green and does not change, the BMS is likely dead. | |||
If the battery charges fine but the error is still present, the BMS will need to be flashed again. | |||
If it is unable to be flashed over ble or serial, you may need to open the battery up to STLink it. | |||
