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. The Lipo Battery Management System Red Board is a must-have for any expert in the field. With its Smart Master slave BMS, it can handle up to 500A and is compatible with ENNOID Firmware and VESC technology. Say goodbye to battery management complications and hello to efficient and reliable power. 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.
