Product Group Information
PSL-SC series lithium batteries can be connected in series or parallel for greater voltage or capacity. They deliver constant power, fast charging without the need for float, and long cycle life even at higher temperatures, making them a reliable, flexible solution for applications such as renewable energy systems, telecom, UPS, and industrial equipment.
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)

Product Description
The PSL-SC-12350 is part of our Series Capable Rechargeable Lithium (LiFePO4) range. This 12.8V and 35.0Ah battery provides opportunity for increased voltage and capacity. Features include BMS Optimization, Lightweight Lithium, Lithium 2X Power, Lithium 40% Lighter, Lithium Cycle Life, Lithium Maintenance Free, Lithium Powersport Performance, Lithium Safety, Not For Starting, and Serial/Parallel Benefit. These batteries are commonly used in Edge Data Center, Medical, Mobility, Solar, Sport Recreation, Transport, and Wind requiring series capability. 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.
For further charging and maintenance information see the lithium resource center on Power-Sonic.com.
