The 48V 314Ah LiFePO4 Energy Storage Battery Pack uses 16 series-connected (16S) high-capacity 314Ah prismatic LiFePO4 cells, delivering a nominal system voltage of 51.2V and a total storage capacity of approximately 16.08kWh (about 16kWh).
The battery pack integrates a JK V19 16S 200A smart BMS, a 10A parallel current-limiting module, and a built-in 200A air circuit breaker, providing precise battery management, reliable multi-unit parallel operation, and comprehensive circuit protection. Up to 16 units can be paralleled to achieve extremely large capacity, making it suitable for home energy storage, off-grid solar, commercial and industrial backup power, and more — delivering a safe, long-life, and scalable energy storage solution for users.
Key Highlights
Integrated JK V19 16S 200A Smart BMS: Equipped with the JK V19 16S 200A intelligent battery management system, it monitors the voltage and temperature of every cell in real time, supports active balancing and multiple protections including over-charge, over-discharge, over-current, and short-circuit. Stable 200A high-current handling ensures safe and efficient operation of the battery pack.
10A Parallel Current-Limiting Module: The built-in 10A parallel current-limiting module automatically limits circulating current when multiple battery packs are connected in parallel, preventing parallel surge and reverse current flow, making system expansion more stable and safer.
Built-in 200A Air Circuit Breaker: Comes standard with a 200A air circuit breaker for one-touch on/off of the main circuit, automatic tripping on short-circuit or overload, and easier, safer routine maintenance and emergency shutdown.
15+ Years of Daily Service Life (80% Depth of Discharge): Thanks to the excellent cycle performance of LiFePO4 cells, the battery pack can last over 15 years under daily use with an 80% depth of discharge, resulting in lower long-term operating costs.
Extreme Weather Capability — Wide Operating Range of -20°C to 60°C: Reliable operation in both severe cold and extreme heat, confidently handling a wide variety of climate conditions.
Up to 16 Units in Parallel for Ultra-Large Capacity: Supports paralleling up to 16 battery pack units, with capacity expandable on demand to tens of kilowatt-hours, meeting large-scale storage needs from residential to commercial and industrial applications.
Application Scenarios
Home energy storage and residential PV, off-grid solar storage systems, commercial and industrial backup power, telecom base station backup, and remote-area power supply — any storage scenario requiring long life, scalability, and reliable wide-temperature operation.
