48V 300AH LiFePO4 Battery

A Lithium-Ion battery advantages are the wide operating temperature range, excellent cycling performance, low internal resistance and high efficiency .

In off-grid solar , energy efficiency is crucial importance. The energy cycle efficiency (discharge from 100% to 0% and back to 100% charged) of the average lead- acid battery is 80%.The cycle 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 . In contrast, a LFP battery will still achieve 90% efficiency under same condition.
