Victron Energy LiFePO4 battery 12,8V/20Ah Lithium SuperPack

Product detailed description

The battery has an integrated BMS and safety disconnector SuperPack batteries are very easy to install and do not require any additional equipment. An internal switch disconnects the battery in case of over-discharge, overcharging or high temperature. It is therefore a great replacement for lead-acid battery systems without the need to install additional protective elements. Resistant to incomplete charging Lead acid batteries fail prematurely due to sulphation: - If the battery is discharged for an extended period of time or is rarely fully charged. - If left partially charged or fully discharged. The lithium battery may not be fully charged. Life even improves slightly if partially charged instead of fully charged. This is the main advantage of a lithium-ion battery compared to a lead-acid battery. High efficiency In certain applications (especially islanded systems), energy efficiency can be crucial. The energy efficiency (discharge from 100% to 0% and back to 100% charge) of the average lead acid battery is 80%. The energy efficiency of a lithium-ion battery is 92%. The charging process of lead-acid batteries becomes particularly inefficient when they reach 80% state of charge, resulting in efficiencies of 50% or less in solar systems where several days of energy reserve is required (batteries operating in the 70% to 100% range state of charge). In contrast, a lithium-ion battery will continue to achieve 90% efficiency even under moderate discharge conditions. In addition, compared to lead-acid batteries, they achieve a significantly higher cycling life at a lower weight. Parallel connection option Batteries can be connected in parallel to increase capacity, but cannot be connected in series. Use only in the upright position.
