USB cable 

Maxkgo All-in-one BMS 12S 70A


Step 1: Complete the BMS assembly according to the wiring diagram

(Since we are using a 12S battery pack, we wire it according to the 12S wiring diagram)

After completing the wiring, turn on the BMS switch, and the LED screen will display the firmware version V1.3 (the firmware is 1.4, and it will display 1.3 after burning)


Step 2:Start firmware upgrade via USB

Connect the BMS board to the computer with a USB cable, and open the firmware version 5.2 to upgrade.

① Click "Connection" > Click "Refresh" > Click to connect to BMS > Click "ok".

 ② Click "Firmware"> Tick "Show non-default firmware" >Click to download version 5.2> Choose "YES".

③  After Click “OK”, the firmware 5.2 starts downloading

 ⑤ Click "Cell Management"> Fill in "Cell monitor count" according to the BMS type> Fill in "Cells in series" according to the battery pack specification> Click to download the program> Click "Save"> Click to disconnect the USB port.

(After the download of the new firmware, the battery specification information must be rewritten into the BMS_Tool. )
