Master-XLITE is a modular, charge only BMS based on the popular XLITE platform
Description:
Charge only, Smart BMS with VESC tool compatibility
Master & slave configuration
up to 20 x 12S modular slaves (enable split packs, modular packs, parallel packs etc.)
2 wires ISOSPI communication between Master & slave (up to 2 meters distance between each slave)
Cell voltage, humidity, internal & up to 8 external temperature sensors, charge current, SoC, SoH, Wh, Ah, pack & charger voltages monitoring
Isolated CAN bus & Bluetooth connectivity
JST PH 2.0mm connectors
XT30 connectors for battery & charger connection
Support N.O. momentary push button with LED
1 x I2C bus (support most SSD1306 displays & some other I2C devices)
2 extra outputs (for optional pre-discharge & discharge signals) see XLITE-SHIELD
Buzzer , Status LED, automatic wake-up & auto-shutdown
Status: In stock
2025/04:
Charge issue when VESC is OFF and CAN plugged-in acknowledged.
Fix: Add an inline120ohm resistor on the Master-XLITE CANh output. Next revision of Master-XLITE will have this resistor included on the PCB directly to limit current drain on the CANh line
