Victron Smart Lithium Batteries
Lithium battery 12.8V & 25.6V Smart The market for battery systems is developing rapidly. There is a growing demand for efficient batteries with a large energy density. Victron Energy has a suitable response for this demand: the Victron Lithium-ion battery system. This is comprised of a very modern battery with an advanced control- and security system; the so-called Battery Management System (BMS). The BMS controls the charging and discharging, immediately takes action when certain (critical) values are exceeded and safeguards an efficient energy-transfer. 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: 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. 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 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. 100% charged) of the average lead acid battery is 80%. The round trip energy efficiency of a LFP battery is 92%.
Rugged A lead-acid battery will fail prematurely due to sulphation if: • If it operates in deficit mode during long periods of time (i. e. if the battery is rarely, or never at all, fully charged). • If it is left partially charged or worse, fully discharged (yacht or mobile home during winter time). A 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.
