Positeck BMS

Li-ion BMS Products

UK Based Li-ion Technology Specialists

Li-ion has become the chemistry of choice for many industries due to its high energy density, remarkable cycle life and high charge and discharge rates. Li-ion cells, partly due to the characteristics that make them so successful,  if not treated correctly, can be more dangerous than the traditional NiMH/NiCd and Lead based chemistries. Positeck BMS systems are designed to ensure the monitored Li-ion cells cannot be taken beyond their safe operating limits, helping ensure the battery remains safe and reliable. All Positeck BMS systems employ a hardware first approach – our battery management systems are designed to pass regulatory testing without the BMS firmware even running.
