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: 2V/cell). A 12,8V LFP battery therefore consists of 4 cells connected in series; and a 25,6V battery consists of 8 cells connected in series.


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 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.

Size and weight:
Saves up to 70% in space
Saves up to 70% in weight

LFP 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.
Endless flexibility
LFP batteries are easier to charge than lead-acid batteries. The charge voltage may vary from 14 V to 16 V (as
long as no cell is subjected to more than 4,2 V), 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.
