Product Description

48V 50ah Rack-Mount Battery 2.5kwh Solar Battery -LiFePO4 Lithium Ion-LFP-Rechargeable-off-Grid Power Supply with Built-in BMS-2u

Product introduction:
EverExceed Lithium Iron batteries are absolutely vital to Uninterruptible Power Supply (UPS) systems, switching and transmission functions, emergency and security systems, industrial fire monitors and alarms, data centers, process control installations, signaling systems and more. EverExceed Lithium Iron batteries - the innovation needed for today's UPS applications Green Energy, meeting a wide range of UPS needs with reliable and robust batteries for backup power of either 12VDC, 24VDC, 48VDC, 96VDC, 192VDC, 240VDC, 384VDC, 480VDC, 800VDC. 

Key Features:

MORE USABLE CAPACITY	USER FRIENDLY BMS
LFP provides 100% of usable energy, so that you can discharge the battery entirely without causing downtime of your solar site, saving cost of diesel generator fuel.	User friendly BMS monitors and communicates regarding the SOC, SOH, protects the system from short-circuit, high and low discharging and charging, high temperature etc.
FASTER CHARGING	EASY INSTALL ATION
Charges much faster than sealed lead acid batteries, giving you access to reliable power quicker to continue your operation. Can fully charge within 2-3 hours which is impossible for VRLA.	EverExceed LFP batteries are designed to be drop-in replacement for sealed lead acid batteries without additional labor cost.
HIGH DISCHARGE RATE	SUPERIOR DEEP CYCL ING ABILITY
Ability to deeply discharge the battery at a high rate of discharge while maintaining a high energy capacity.	Superior deep cycle ability provides highly efficient cycling and float service with great energy density .
