Description
LiFePO4 batteries are the safest lithium-ion batteries on the market. The nominal voltage of a LiFePO4 cell is 3.2V, as opposed to 2V for lead-acid batteries, so a 12.8V battery contains 4 cells connected in series, and a 25.6V battery contains 8 cells connected in series.
It is not necessary for a LiFePO4 battery to be fully charged. The lifespan of such a battery is actually improved by partial charging rather than full charging, which is also the major advantage over lead-acid batteries.
Other advantages include the wide temperature range in which it can operate, excellent cycle life, low internal resistance and high efficiency, which stands at 92%.
Cell voltages, temperature and fault status can be monitored via Bluetooth, which is very useful for identifying potential problems, such as cell imbalance.
