FL-48 Series
SKU: FL-48-400 / FL-48-600 / FL-48-800High-density 48V LiFePO4 battery designed for 3-shift heavy-duty operations. Replace large lead-acid banks with a compact, high-energy solution.
Power for Multi-Shift Operations
The FL-48 Series is engineered for the demands of high-throughput distribution centers and manufacturing plants. With capacities ranging from 400Ah to 800Ah, it replaces heavy, cumbersome 48V lead-acid battery systems.
Experience zero voltage drop. Unlike traditional batteries that lose power as they discharge, the FL-48 maintains consistent voltage output, ensuring your forklifts operate at peak performance until the very last percent of charge.
Eliminate battery rooms and changing stations. With opportunity charging capabilities, a single FL-48 battery can support continuous 24/7 operations by charging during short operator breaks, significantly increasing fleet utilization and reducing total cost of ownership.
Eliminate Battery Swapping
Fast charge (1C rate) capability means you can charge the battery in 1-2 hours during breaks. No need for expensive multi-battery inventory.
Space Saving
The compact design reduces the physical footprint by up to 40% compared to lead-acid, allowing for better forklift counterweight distribution.
Smart BMS Integration
CANbus communication provides real-time data on State of Charge (SOC), State of Health (SOH), and fault diagnostics to your fleet management system.
