lifepo4 12v 100ah battery pack Why lithium-iron phosphate?
Lithium-iron-phosphate (LiFePO4 or IFR) is the safest of the mainstream li-ion battery types.
The nominal voltage of a IFR cell is 3,2V (lead-acid: 2V/cell). A 12,8V LiFePO4 battery therefore consists of 4 cells connected in series; and a 25,6V battery consists of 8 cells connected in series.
lifepo4 12v 100ah battery pack Efficient
In several applications (especially off-grid solar and/or wind), energy efficiency can be of crucial importance.
The round trip energy efficiency (discharge from 100% to 0% and back to 100% charged) of the average lead acid battery is 80%.
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 efficiency 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.

lifepo4 12v 100ah battery pack Expensive?
Lifepo4 batteries are expensive when compared to lead-acid. But in demanding applications, the high initial cost
will be more than compensated by longer service life, superior reliability and excellent efficiency.
IFR batteries are easier to charge than lead-acid batteries.
The charge voltage may vary from 14V to 16V (as long as no cell is subjected to more than 4,2V), and they do not need to be fully charged.
Therefore several batteries can be connected in parallel and no damage will occur if some batteries are less charged than others.
Battery Management System (BMS)
Its essential functions are:
1. Disconnect or shut down the load whenever the voltage of a battery cell falls to 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 of a cell exceeds 50°C.
