80V 404Ah LiFePO4 Forklift Lithium Battery 4000 Cycle Life Heavy Duty Counterbalance

Product Overview

This 80V 404Ah LiFePO4 lithium battery is engineered for heavy duty counterbalance forklifts in the 4-5 ton class, delivering 4000 charge cycles at 80% DOD with the ruggedness required for continuous industrial operation. The IP54 sealed aluminum housing protects cells from dust, water splashes and vibration, while the high-strength structure withstands the shock loads of daily fork truck duty.

Replacing a lead-acid battery with this lithium power pack removes the heaviest maintenance item from your fleet. There is no acid, no watering, no equalization charge and no dedicated charging room ventilation requirement.

Core Selling Point: Industrial-Grade 4000 Cycle Life

In heavy duty applications the battery is the single most expensive consumable. This 80V 404Ah pack is rated for 4000 cycles at 80% DOD and tested to IEC 62660-1 standards, providing 8+ years of dependable power in single-shift duty and reducing lifetime battery cost by up to 50%.

• 4000 cycles @ 80% DOD: designed for continuous operation
• Opportunity charging ready: top up during breaks, no battery change-out
• High rate discharge: 1C continuous, 2C peak for heavy lifting
• IP54 sealed aluminum housing: dust and splash resistant
• CAN bus interface: compatible with major forklift brands

Discharge Characteristics

The robust discharge capability ensures heavy loads are lifted at full speed even under continuous high-current demand, with no voltage sag that could trigger forklift derating or slow hydraulic response.

Frequently Asked Questions

Q1: Is the 80V system compatible with my 4-5T forklift?
A: Please confirm your forklift's nominal voltage and compartment dimensions. Our 80V 404Ah pack is designed for major 4-5T electric forklift platforms.

Q2: Can opportunity charging damage the battery?
A: No. LiFePO4 chemistry and the smart BMS are designed for frequent partial charging. Opportunity charging during breaks is encouraged and extends available operating time.

Q3: What about vibration and shock in heavy duty use?
A: All cells use welded busbar connections and the pack is secured in a reinforced aluminum housing with internal dampening, tested to industrial vibration standards.

Q4: Do you provide installation support?
A: Yes. We provide installation manuals, video guidance and remote technical support. On-site commissioning can be arranged for large fleet projects.
