Key Benefits of Our 48V Forklift Battery
Delivers stable lifting power for heavy loads and continuous daily operations.
High Power Density
Delivers strong, consistent power for smooth lifting and driving, ensuring rapid acceleration and stable performance even under heavy loads.
Consistent Performance
Unlike lead-acid batteries that suffer voltage sag during discharge, this lithium forklift battery delivers stable output from start to finish, supporting consistent heavy-load performance across the entire shift.
Fast Charging
Designed for rapid charging, it can reach full power in 1–2 hours and supports opportunity charging during breaks, minimizing downtime and the need for backup batteries.
Wide Temperature Range
Our lithium forklift battery maintains stable performance across a -20°C to 60°C temperature range, with an optional heating function to ensure reliable charging and discharging in even lower temperatures.
Intelligent Monitoring
With CAN or RS485 connectivity, the built-in BMS provides real-time visibility into charge level, temperature, and battery condition, supporting proactive maintenance and long-term reliability.
Eco-Friendly Operation
With no toxic heavy metals and higher energy efficiency than lead-acid alternatives, this lithium forklift battery supports greener, more sustainable warehouse operations.
Is It Worth Switching from Lead-Acid to Lithium Batteries?
Forklift battery management is a major operational challenge in warehouses.
Lead-acid batteries have a lower upfront cost, but require multiple packs per truck, dedicated battery rooms with charging stations, ventilation, and acid mist management. Regular maintenance-including weekly watering, monthly equalization charging, and ongoing operator training-adds significant hidden costs.
Lithium batteries involve a higher initial investment, but simplify operations and reduce ongoing expenses.
FL51460
The FL51460 battery, with 23.5 kWh capacity, can power a 2.5-ton counterbalance forklift for a full shift under normal operating conditions (8–10 hours).
Opportunity charging during breaks is possible without impacting battery lifespan. Backup batteries and dedicated battery rooms become unnecessary, freeing space and reducing operational complexity while ensuring continuous forklift availability.
Does the lithium battery lose power toward the end of its charge?
No. This is determined by the characteristics of lithium iron phosphate-the discharge curve is very flat. When you're down to 20% charge and lifting a heavy pallet, the speed is basically the same as when fully charged.
By contrast, lead-acid batteries lose noticeable power as their charge drops. Lifting heavy pallets at 40% capacity can feel significantly slower, impacting productivity and operational efficiency.
About lifespan
Polinovel lithium batteries are rated for up to 4,000 cycles. While theoretical calculations suggest more than ten years at one full cycle per day, realistic usage and cell aging result in an expected service life of 5–8 years.
Lead-acid batteries typically show noticeable capacity decline after 2–3 years of normal use, making heavy-load handling increasingly difficult. One lithium battery can therefore provide the equivalent service of two to three lead-acid batteries.
Low Maintenance Costs
Lithium batteries require minimal maintenance. No watering, no equalization charging, and no concerns about sulfation. The integrated BMS monitors battery health in real time and alerts operators if intervention is needed.
By eliminating routine maintenance, labor and time previously devoted to battery upkeep are freed, reducing operational costs and simplifying fleet management.
Specifications & Fit
The FL51460 battery measures 800 × 546 × 335 mm, fitting most mainstream counterbalance forklifts. It uses a REMA connector and serves as a direct replacement for lead-acid batteries with no vehicle modifications required.
For forklift models with non-standard dimensions, custom sizing options are available to ensure proper fit and compatibility.
Cold Storage Applications
Lead-acid batteries experience significant capacity loss at sub-zero temperatures, often achieving only half their rated runtime in –10 °C environments.
The FL51460 operates down to –20 °C. In tests at –15 °C, capacity drops by approximately 20%, but runtime still exceeds 6 hours.
For operations below –25 °C, the heated version preheats automatically before startup, ensuring reliable performance and preventing downtime in extreme cold.
When is replacement appropriate, and when is there no rush?
If your forklift only runs two or three hours a day and your current lead-acid batteries aren't giving you major problems, the payback period for switching to lithium will be quite long-it might not be cost-effective.
But if you're running two shifts, three shifts, high-intensity use, or dealing with special environments like cold storage, or if you're short on maintenance staff and want less hassle, lithium's advantages become very clear.
Whether switching makes sense for your specific situation-send over your forklift model, battery compartment dimensions, and daily usage hours, and let the technical team run the numbers for you.
It's not the right choice for every situation, but when it is the right choice, it really does save you headaches.
