This product is a new type of backup power supply for the development of high-tech products, with integration, miniaturization, light, intelligent, standardized, environmental protection and other characteristics, can be widely used in indoor distribution stations, integrated base stations, marginal stations, distributed power supply and other fields.
Adopted by the high safety performance, lithium battery cathode material for lithium iron phosphate, high safety, high stability, high cycle life, high specific energy, specific power, low temperature performance is superior, but large current charge and discharge, and many other advantages, at the same time, using suitable for communication demand special high performance battery management system (BMS), with the charge, over discharge, short circuit, over-current (load), temperature, flow, total pressure protection, charging under the secondary electricity, balanced and various protective functions, and provides CAN 、 RS485 communication interface and the upper machine to realize remote monitoring, can be connected to the base station power environmental monitoring systems,Intelligent software anti-theft design，Ensure the life of lithium battery and reduce the daily maintenance work.
Product features
The internal single battery adopts the anode material of lithium ferrous phosphate (LiFePO4), which has high safety, high energy density and excellent cycling performance;
The battery pack is equipped with BMS, a high-performance battery management system, which has the protection functions of over discharge, over charge, over current, high temperature and low temperature to ensure the safety of the battery pack;
Automatic charge and discharge management. The monitoring unit automatically measures the charge and discharge current of the battery and manages the floating charge and even charge of the battery;
When the battery voltage is lower than the alarm value, it will alarm, and when the voltage is too low, it will automatically power down to protect the battery;
The battery pack has good electromagnetic compatibility;

Battery will be vibrated 30 minutes in three mutually perpendicular directions and changing frequency between 10 to 55Hz. The rate of scanning frequency is from 10 Hz to 55Hz with the rate of 1Hz per min.
Vibration frequency：10-30Hz
amplitude：0.38mm
vibration frequency：30-55Hz:
amplitude：0.19mm
The battery shall not rupture, smoke, explode or leak.
Battery electric voltage ≥48V
Constant Temperature/Humidity Test
Keep the battery at 40±2℃ and 90%-95%RH for 48 hrs after complete charge.
After the test, keep the battery at 20±5℃ for 2 hrs. Discharge at 10A constant current discharge to the termination voltage.
Appearance of the battery shall not rust, smoke or explode. Discharge Capacity ≥80%
High Temperature Performance Test
Keep the battery at a hot oven with 55±2℃ for 2 hrs, then measure the capacity with constant discharge current 0.5C to discharge protection point after complete charge. After the test, keep the battery at 20±5℃ for 2 hrs.
Appearance of the battery shall not rust, smoke or explode
Discharge Capacity >90%
Low Temperature Performance Test
Keep the battery at -20±2℃ for 16-24 hrs, then measure the capacity with constant discharge current 0.5C to discharge protection point after complete charge.
After the test, keep the battery at 20±5℃ for 2 hrs.
Appearance of the battery shall not rust,smoke or explode
Discharge Capacity >55%
Over-charge test
Charge in accordance with the following two ways (Choosing one between the two).
(1)Charge at 1C current for 90min or until voltage of some single battery reaches 5.0V (stop test when fulfills either
condition).
(2)Charge at 3C current until the voltage of some single battery reaches 10.0V, then stop the test.
The battery shall not explode or catch fire.
Over-discharge test
Charge the battery. Place at 20±5℃ for 1h, then discharge in 1/3C current at same temperature until some cell’s voltage is 0V.
The battery shall not explode or catch fire.
Short-circuiting Test
After charge batteries, place at 20±5℃ for 1h.
Short the battery for 10min, the external circuit
resistance should be less than 5mΩ.
The battery shall not explode or catch fire.
