Product Group Information
Long cycle life and dependable performance with advanced connectivity. Integrated communications protocols allow seamless communication with external systems, providing real-time data on voltage, current, temperature, and state of charge. With built-in BMS protection these batteries are ideal for energy storage, telecom, UPS, and other applications where system integration and monitoring are critical.
Long Term Storage Information
Avoid storing batteries and cells long term in extreme temperatures or direct sunlight. The battery should be stored at a -10℃ ~ +45℃ range environmental condition. If the battery must be stored for a long time (over 3 months), the environmental condition should be:
a. Temperature: 23±5℃
b. Humidity: 65±20%RH
c. The storage voltage should be 3.3V~3.4V per cell. (3.4V for 0.5C charging; 3.3V for resting)
Operating Temperature Range Charge
32°F (0°C) to 113°F (45°C)

Product Description
The PSL-ES-481000 is part of our Energy Storage Lithium range. This 48.0V and [[ps_common_items.field_values.131]]Ah battery provides real-time hardwired system data. Features include BMS Optimization, Communication Port, Lightweight Lithium, Lithium 2X Power, Lithium 40% Lighter, Lithium Cycle Life, Lithium Maintenance Free, Lithium Powersport Performance, Lithium Safety, and Not For Starting. These batteries are commonly used in Backup Power Systems, Edge Data Center, Energy Storage, Signaling (Air,Rail,Sea), Solar, Telecomm, UPS, Utility, and Wind requiring communications protocols. Backed by decades of expertise, Power-Sonic batteries are subject to stringent quality controls through each step of the manufacturing process to ensure compliance, performance consistency, and reliability.
Charging Description
Cycle Applications: Apply constant voltage charge at 3.60VPC – 3.65VPC (14.4 to 14.6 volts for 12V Monobloc) at 20°C. The initial charging current should be set at less than C/4 Amps. Terminate the charge when the current falls to a 3% capacity rate to avoid overcharging.
Stand-By or "Float" Service: Apply constant voltage charge of 3.35VPC – 3.45VPC (13.4 to 13.8 volts for 12V Monobloc) at 20°C. When held at this voltage, the battery will seek its own current level and maintain itself in a fully charged condition.
