Efficient and fast charging and discharging For the lithium iron phosphate battery cells, the single cell voltage is always 3.2V, all voltage, current, power (kW) and energy (kwh) applications are based on this voltage. High voltage lithium battery system usually refers to the battery system voltage is greater than or equal to 96V, for example, 192V 50Ah battery system is 1P60S (60 cells series connected) cell connection and based on 50Ah single cell capacity. And 240V 50Ah battery is 1P75S cell connection, 384V 100Ah battery is 1P120S cell connection based on 100Ah cell, etc. We also can parallel cell first for double or triple total capacity. The corresponding battery capacity is usually 50Ah, 100Ah, 150Ah, 200Ah, etc. For high voltage, in the single-cluster battery rack, the battery modules are always connected in series to achieve a higher voltage. Moreover, there is a high voltage DC main unit is needed to manage this rack. The main function of the high voltage DC main unit is to manage all the BMU units of this cluster through the master BMS, meanwhile to provide startstop, protection and other functions for this rack. Please reference left picture for a HV lithium battery system.

Features of LiFePO4 Battery
- Longer Cycle Life: Offers a significant longer cycle life and longer float/calendar life than lead acid batteries helping to minimize replacement cost and reduce total cost of ownership.
- Higher Power: Delivers twice the power of lead acid batteries, even high discharge rate, while maintaining high energy capacity.
- BMS Protection: The battery is also equipped with an internal Battery Management System that can monitor and optimise each Prismatic cell within the battery during normal operation. It will protect the battery pack from over charge, over-discharge, over temperature & short circuit. The BMS helps to ensure safe and accurate operation of the battery.
- Charging: Designed to work with AGM chargers.
Safety: Advanced LiFePO4 cell design includes various safeguards including high temp thermal fuse, flame retardant additive and pressure relief valves. - Increased Flexibility: Battery Specialist LiFePO4 batteries are a flexible combine for different scale system. From 12v up to 786 volt.
