Why lithium-iron-phosphate?
Lithium-iron-phosphate (LiFePO4 or LFP) is the safest of the mainstream li-ion battery types. The nominal voltage of a LFP cell is 3,2V (lead-acid batteries: 2V/cell). A 12.8V LFP battery consists of 4 cells connected in series; and a 25.6V battery consists of 8 cells in series.

Service life
LFP battery does not need to be fully charged. Service life even slightly improves in case of partial charge instead of a full charge. This is a major advantage of LFP compared to lead-acid. Other advantages are the wide operating temperature range, excellent cycling performance, low internal resistance and high efficiency (see below).

In several applications (especially off-grid solar and/or wind), energy efficiency can be of crucial importance.
The round trip energy efficiency of a LFP battery is 92%.
The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached, resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy is required (battery operating in 70% to 100% charged state). In contrast, a LFP battery will still achieve 90% efficiency under shallow discharge conditions.

Cell balancingand and monitoring
LFP batteries have integrated cell balancing and cell monitoring. Up to 5 batteries can be paralleled and up to 4pcs 12V batteries or 2pcs 24V batteries can be series connected,so that a 48V battery bank of up to 1500Ah can be assembled. The cell balancing/monitoring cables can be daisy-chained and must be connected to a Battery Management System (BMS).

Battery Management System (BMS)
BMS Function:
1. Disconnect or shut down the load whenever the voltage of a battery cell decreasesto less than 2,5V.
2. Stop the charging process whenever the voltage of a battery cell increases to more than 4,2V.
3. Shut down the system whenever the temperature exceeds 75°C. 



Compared with same capacity of lead acid batteries, lifepo4 batteries are 1/2 smaller in size, 2/3 lighter in weight, 5 times longer in cycle life, which are more compact, light-weight and eco-friendly.
