SOETECK SY-LI Series 48V Lithium Iron Phosphate Battery (LiFePO4) for Lead-Acid Battery Replacement

SOETECK SY-LI Series 48 V Lithium Iron Phosphate Battery (LiFePO4) for Lead-Acid Battery Replacement is engineered as a drop-in solution for motive-power and stationary applications that previously relied on lead-acid blocks. Built around a robust LiFePO₄ chemistry, the unit delivers 4.8 kWh of usable energy at a nominal 48 V / 100 Ah, while weighing only 37.5 kg—approximately one-third of an equivalent lead-acid pack.

A highly integrated Battery Management System safeguards every cell, balancing charge and regulating current up to 100 A continuous ou 100 A pulse. The pack sustains ≥ 3000 cycles at 0.5 C and 80 % DOD, translating into an expected service life of five to ten years under normal conditions. Self-discharge is held below 3 % per month, minimising downtime in seasonal or standby roles.

Its rugged construction (IP6X ingress rating, operating range –20 °C to 55 °C) supports indoor and outdoor deployment, from AGV drive trains and recreational-vehicle house banks to solar-hybrid storage cabinets and critical emergency reserves. By combining high cycle life, low maintenance and rapid CC/CV charging, the SOETECK SY-LI Series 4.8 kWh 48 V Lithium Iron Phosphate Battery (LiFePO4) for Lead-Acid Battery Replacement offers a clear pathway to lower total cost of ownership and improved system uptime for industrial and commercial operators.

Within the SOETECK SY-LI Series 48 V Lithium Iron Phosphate Battery (LiFePO4) for Lead-Acid Battery Replacement range, the current model—internally designated LUB48100PA—offers a balanced specification of 48 V / 100 Ah, 100 A continuous discharge and an IP6X shell for dusty industrial sites. Its compact 522 × 240 × 218 mm housing and 37.5 kg mass simplify retrofits where space and weight are limited. Should future capacity variants be added, each will maintain the same BMS architecture and connection rules (series ≤ 2, parallel voltage Δ ≤ 2 V) to ensure seamless mixing within larger battery banks.
