IP65 Outdoor lithium battery 48V 50AH

System Profile

This product is an advanced product developed to meet the requirements of the new backup power supply of the current communication operators under the new trend of communication, with the characteristics of integration, miniaturization, lightness, intelligentization, standardization and environmental protection, it can be widely used in outdoor tower lamp-post station, indoor distributed weak electric well, micro-station and other environmental bad scenes, backup power supply for communication equipment such as RRU and AAU at the end of communication network. The utility model can meet the application scenarios of wall hanging, holding pole, angle steel tower and so on, and support the installation modes of flag installation, paperback installation, landing, etc.

Products in the sun, rain, dripping, wind, freezing, dust, wet outdoor environment, can be normal operation.

System Characteristics

1) The electric battery cell adopts the controllable double-valve structure design safety valve, the safety is high.

2) Integrated Design: 16 Series Battery Modules + BMS + aluminum die-casting enclosure.

3) High energy density, stable discharge platform, long service life, greatly reduce base station rejection rate.

4) The Modular design can be connected in parallel to expand the capacity according to the actual need.

5) All-round warning and protection functions (overcharge, overdischarge, short circuit, overload, overcurrent, high temperature, low temperature, equilibrium, dormancy).

6) Intelligent design, with remote sensing, remote signal functions, through the dynamic monitoring system remote communication.

7) The panel at the bottom of the box body is convenient and suitable for quick operation and outdoor wiring maintenance.
