Lithium Battery 12VDC 200Ah Smart LiFePO4
Lithium-iron-phosphate (LiFePO4 or LFP) is the safest of the mainstream li-ion battery types. The nominal voltage of an 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.
Lithium Batteries require additional components during installation to make the system operate properly. These should be professionally installed to help avoid costly non-warranty failures.
A lead-acid battery will fail prematurely due to sulfation:
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 an 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 are required (battery operating in 70% to 100% charged state). In contrast, a LFP battery will still achieve 90% efficiency under shallow discharge conditions.
Size & Weight:
Saves up to 70% in space. Saves up to 70% in weight.Expensive?
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.
