MKBMS is developed based on the open source materials of DieBieMS and ENNOID BMS. Currently MKBMS is compatible with ENNOID firmware.
MKBMS is based on the modular LTC6813 battery management platform and connects to slave boards and integrated boards through the ISOSPI interface.

LTC6813 18S Slave Features
- Aluminum alloy PCB, better heat dissipation effect
- Compatible with MKBMS and ENNOID BMS
- 5-18 cell level monitoring per board
- 1+8 temperature sensors per slave
- Self-powered by the monitored cells
- Ultra-low power consumption, sleep mode = 6uA
- Daisychain Master ISOSPI communication
- 1.2mV accuracy, -40 to 120C operation
- 33 ohm balance resistors (0.125A capacity) on all channels
