Lithium battery systems have have been our core focus since 2007. Until recently we focused exclusively on Lithium Iron Phosphate batteries. LiFePo4 batteries are among the safest lithium battery chemistries . The voltage of LiFeP04 cells closely match lead acid making them an ideal upgrade to lead batteries in many applications. NMC lithium cells (Nickel Manganese Cobalt) have a higher power and energy density than LiFePo4 but are more volatile if they fail. A battery management system is a requirement to operate all lithium batteries safely. Our BMS systems protect batteries against the following conditions: Over/ under voltage,over current, temperature and short circuit. The health of every battery cell is monitored for optimal life and performance. The BMS is connected to the web and uploads performance data, fault codes and operational parameters in real time for remote monitoring.
