The VFBMS32 (or VBMS) is a BMS made by Benjamin Vedder from VESC and Fungineers. This is a highly sophisticated, charge only, Smart BMS module with Bluetooth and Canbus communications.

Important SET UP information;

• ENABLE "BLOCK SLEEP" ON FIRST CONNECTION* *- If you don't have this enabled, the VBMS will never wake up upon the initial connection. Make sure this is disabled afterwards.
• CONNECTION ORDER- Battery XT30 first, followed by the balance leads LOWEST to HIGHEST. YOU MUST CONNECT EVERYTHING UNDER 30s for the BMS TO INITALIZE! Temp sensors and CAN connections have no connection order preference / timer.
• DISCONNECTION ORDER - Balance leads HIGHEST to LOWEST first, followed by the Battery XT30. No timer here, and the peripheral wires don't have a preference.
• You may need to set up your IC CHIP values and TEMP SENSORS according to your pack.
• Update your BMS by reflashing the FIRMWARE first, then the VBMS 32 MICRO PACKAGE.
• To be able to see your BMS data thru CAN on your Thor/ Controller, please go to Motor Config > BMS > and set it to VESC BMS, and Write the settings.
• If pairing a VBMS32 to a Thor300, you must; Match 5V to 5V, GND to GND, Can H (high) to CAN P (positive), and CAN L (low) to CAN N (negative)
• If your BMS is glitching out or is refusing a charge, please watch our set up guide. We show how to troubleshoot / debug the BMS through the ESP programmer. This section starts at 7:00.
• If your VBMS or X7 Funwheel is beeping, check out that same set up video starting at 14:25.
