Click here to learn more information about BMS
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 within 150V.
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 Slave Board (LTC6811-12W-AL) Features:
Variant:
*The first temperature channel is used by slave board itself. The following 4 temperature sensors are not in the package lists but means an interface to connect 4 temp sensors at most. |

2 x LTC6812-15S: 15S + 15S ( Optimal)
2 x LTC6813-18S: 15S + 15S (Two slaves partially loaded)
MKBMS monitoring 35S pack :
3 x LTC6811-12S: 12S+12S+11S (Good)
3 x LTC6812-15S: 12S+12S+11S (Three slaves partially loaded)
2 x LTC6813-18S: 18S + 17S (Optimal choice)
*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
