Heavy-Duty LiFePO4 Battery for Four-Wheel Electric Forklifts
Industrial-grade lithium-ion power system engineered for four-wheel counterbalanced electric forklifts (2.0T to 5.0T). Designed as a direct drop-in lead-acid replacement, matching factory physical dimensions and vehicle counterweight requirements without structural truck modifications. Integrates cell-level safety monitoring and multi-protocol CAN bus communication to interface directly with mainstream forklift controllers (Curtis, Zapi, Sevcon).
Key Features
Prismatic Cell Integration: Built with Grade-A LiFePO4 cells sorted by internal resistance (≤ 0.5 mΩ) and capacity deviation (≤ 1%) to ensure uniform pack aging and a design life of 4,000+ cycles at 80% DoD.
Multi-Layer BMS Architecture: Dual-core processor hardware monitors individual cell voltages, current, and module temperatures, providing redundant short-circuit, overcharge, and deep-discharge cutoffs.
High-Rate Opportunity Charging: Supports continuous 1C fast charging, allowing partial recharges during standard shift breaks without electrolyte maintenance or memory degradation.
Thermal & Climate Adaptation: Integrated aluminum cooling plates with optional internal low-temperature heating films, ensuring full power delivery in refrigerated cold-storage facilities down to -30°C.
Exact-Fit Structural Casing: Heavy-gauge welded steel enclosure designed to match OEM center-of-gravity and weight specifications for vehicle stability and safety.

FAQ
Q: Can this lithium battery replace an existing lead-acid battery without modifying the forklift chassis?
A: Yes. The pack is engineered to match the exact physical footprint, weight, and center of gravity of the original lead-acid battery, eliminating the need for structural truck modifications.
Q: How does the battery integrate with the forklift's control system?
A: The integrated BMS uses a standard CAN 2.0B interface (supporting J1939 or custom profiles) to transmit real-time data-such as voltage, temperature, and SoC-directly to the original instrument cluster.
Q: Is opportunity charging safe for multi-shift operations?
A: Yes. LiFePO4 chemistry supports 1C fast charging. Operators can plug the truck in during standard 15-to-30-minute breaks to maintain continuous multi-shift fleet availability without memory degradation.
Q: How does the battery perform in refrigerated or sub-zero environments?
A: Units specified with the low-temperature heating package automatically warm internal cells prior to charging when ambient temperatures fall below 0°C, preventing lithium plating and cell wear.
Q: What safety protections are standard in the BMS?
A: The dual-core BMS provides hardware- and software-level protections against over-voltage, under-voltage, over-current, short-circuit, and extreme operating temperatures.
Q: What are the standard lead times for orders?
A: Standard catalog configurations ship within 15 days. Custom mechanical dimensions or proprietary CAN integration projects require 25 to 35 days for engineering verification and production
