MKBMS is based on the modular BMS of LTC68XX and STM32 MCU, and is connected to one or more slave boards and integrated integrated boards of different sizes through the ISOSPI interface. The modular BMS can be configured for various applications with battery voltages with 400V.
MKBMS is developed based on the open source materials of DieBieMS and ENNOID BMS. Currently MKBMS is compatible with ENNOID firmware. Here, a special thanks to the developers of open source BMS materials.
MKBMS HV Master Mini Board Features：
With charger voltage measurement, humidity sensor, isolated on-board 5V power supply for isolating CAN bus interface and USB Type-C
100V to 400V operation
Voltages measurements for load & battery pack
Bi-directional current monitoring (up to 2500A pulsed, 500A continuous)
Isolated charger detection circuit
Isolated CAN bus interface
Daisychain Master/Slave ISOSPI communication
Single PCB pattern for bolt-on contactor
It can internal power supply or external power supply voltage is 12V
Integrated predischarge circuit
USB & serial interface for configuring and firmware upgrades with the ENNOID-BMS-Tool
*For uneven cell count in series, only the last slave board in the daisy-chained loop should have one cell less connected than the other slaves. Ex: 39S = 10S + 10S + 10S + 9S
MKBMS battery management system implements the following functions:
Current and voltage protection: protect the battery pack from overcharge and overdischarge, thereby extending the cycle life.
Battery health monitoring: monitor the internal resistance of a single battery and the monitoring capacity of the battery pack.
Thermal management: Overheating and under-temperature protection with fan control for cooling or heating.
Support batteries: Li-Ion, Li-Polymer, Li-Phosphate
Intelligent battery balance: passive balance and active balance
MKBMS can be roughly divided into three aspects: automobile, industry, and consumption:
Electric vehicles;
Electric patrol car;
Scenic sightseeing car;
Handling robots;
Automatic forklift;
Electric bicycles;
Electric skateboard;
Electric tools;
Consumer robots, etc.

I must say that those in the western world that keep accusing Chinese people to supply poor quality equipment is only the result of what the westerners are ordering as all they want is cheap stuff in the first place. I haven't yet tested the unit in the long run but everything with it is perfect according to my standards, and they are high to reach
