A battery management system (BMS) is a technology designed to oversee a battery pack, which is an assembly of individual LFP (LiFePO4, lifepo4) cells that allows the delivery of a target range of voltage and current over a specified period of time under expected load scenarios. What does the use of a smart BMS system provide? Our range includes everything from simple and inexpensive CBM boards to the complex BMS123 Smart. Our BMS can be connected via Bluetooth, USB, CAN, or RS232. All lithium-based batteries and cells are susceptible to overcharging or deep discharge, we strongly recommend the use of protection units to extend the life of your battery.
