XLITE-V4 is an updated version and almost a direct drop-in replacement for the XLITE, XLITE-V2 & XLITE-V3
Reminder: Monolitic BMS are not recommended for split packs. We recommend using Master-XLITE and slaves for split pack or using the XLITE-12+ with a 24S slave (see wiring diagram for XLITE-12+ in a 2S+18S configuration)
What's new:
Simplified balance wiring harness
XLITE-24: For 15S packs and above, no more shorted pins or extra balance wires needed. XLITE-V4 is also backward compatible with previous XLITE-V1, V2 & V3 balance harness
XLITE-32: For 27S packs and above, no shorted pins or extra wires needed
Smaller footprint, now with M2.5 mounting holes
Higher charge current handling capabilities
Better overall heat dissipation (runs cooler)
Some other components were upgraded to improve reliability
Optional aluminum enclosure for faster charging rate & additional protection
Description:
Charge only, Smart BMS compatible with the VESC ecosystem
Easy setup with VESC-tool mobile app
Isolated CAN bus & Bluetooth connectivity
Cell voltage, humidity, internal & up to 2 external temperature sensors, charge current, SoC, SoH, Wh, Ah, pack & charger voltages monitoring
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) see XLITE-SHIELD
Buzzer , Status LED, automatic wake-up & auto-shutdown
Boards are sold without accessories. Please buy the appropriate accessories for your own particular needs.
