sales@qcesolarinverter.com Lithium Iron Battery 51.2V (LiFe PO4 Wall Mounted)
Widely used in wind and light energy systems
Main Features:
●Environmental protection and pollution-free costs
●Long cycle life: over 20 times cycle life and over 5 times float life compared to lead-acid batteries, can reduce repeated investment and costs
●Lightweight: 40% of the weight of lead-acid batteries; easy to install.
●High energy density: Compared with lead-acid batteries, can hold twice of energy and with
higher discharge rate and high energy retention rate at the same time.
●Wide temperature range: -20 ℃ -55 ℃
●Ultra strong safety: paired with BMS battery management system, it has achieved over charge,
over discharge, over current, and high or low temperature protection.
●With no memory function.
