High Capacity Forklift Battery 51.2V 460Ah -20°C to 60°C Discharge 58.4V Charge Limit

Product Overview
This 51.2V 460Ah lithium battery is specifically designed for electric forklifts and heavy industrial equipment. Delivering 23552 watt hours of energy, it provides extended shift operation without midday charging. Built with a 2P16S configuration (two cells in parallel, 16 in series), it offers high energy density, long lifespan, fast charging, and zero memory effect. The intelligent Battery Management System monitors voltage, current, temperature, and state of charge, displayed directly on the built in screen. Communication via CAN and 4G enables remote fleet management and real time diagnostics.

Key Technical Specifications
Rated voltage is 51.2V with 460Ah rated capacity and total energy of 23552Wh. System charging termination voltage is 58.4V. System discharge termination voltage is 40V. Individual cell charging protection voltage is 3.65V, and individual cell discharge protection voltage is 2.5V. Rated discharge current is 300A. Maximum charging current is also 300A. Dimensions are 1030mm length, 630mm width, and 627mm height. Weight is 980 kilograms. The discharge plug is Anderson 320A. The charging plug is REMA DIN320. Communication interfaces include CAN bus and 4G cellular.

Discharge Performance
Rated continuous discharge current is 300 amps, capable of powering heavy load forklifts lifting maximum rated loads. The discharge working temperature range is -20°C to 60°C, allowing reliable operation in cold storage warehouses and hot loading docks. System discharge termination is set at 40V to protect cells from over discharge. Individual cell protection cuts off at 2.5V per cell.

Charge Parameters
Charging uses CC CV method with system charging termination at 58.4V. Maximum charging current is 300 amps for fast turnaround between shifts. The standard charging operating temperature range is 0°C to 55°C. For sub zero charging, a battery heating system is required. Individual cell charging protection voltage is 3.65V. The REMA DIN320 charging plug is designed for high current industrial chargers.

Temperature Range
Charging operating temperature range is 0°C to 55°C. For environments below freezing, the battery requires an external or integrated heating system to warm cells before charging. Discharge working temperature range is -20°C to 60°C, allowing the forklift to operate in cold storage facilities as low as -20°C and in hot indoor environments up to 60°C.

Built in Display and Monitoring
The battery includes a built in display screen showing voltage, current, and state of charge (SOC) in real time. Operators can quickly check remaining battery life without external tools. The display also shows fault codes if any protection event occurs, simplifying troubleshooting.

Communication and Fleet Management
CAN bus communication allows the battery to talk directly to the forklift controller and charger, optimizing charging profiles and providing battery data to the vehicle. 4G cellular connectivity enables remote monitoring of battery status, location, cycle count, and health from a central fleet management system. This is especially useful for warehouse operators with multiple forklifts, allowing predictive maintenance and shift planning based on actual battery condition.

Forklift Specific Features
Lithium forklift batteries offer several advantages over traditional lead acid batteries. No memory effect means opportunity charging during breaks does not reduce capacity. Fast charging at 300A can fully recharge the battery in about 1.5 to 2 hours compared to 8 hours for lead acid. Lightweight design (though still 980kg) is still generally lighter than an equivalent lead acid battery, improving forklift efficiency and reducing floor loading. No watering, no acid spills, and no corrosion means lower maintenance costs and cleaner work environments.

Applications
This battery is designed for counterbalance forklifts, reach trucks, pallet stackers, and other electric material handling equipment. It is suitable for warehouses, distribution centers, manufacturing plants, cold storage facilities, and port terminals where high intensity lifting and long shifts are common. The high discharge current of 300A supports heavy lifting and fast travel speeds.

Installation and Compatibility
The battery comes with an Anderson 320A discharge plug standard on most electric forklifts. The charging plug is REMA DIN320, a common standard for industrial forklift chargers. Verify compatibility with your forklift model before purchase. The battery dimensions (1030x630x627mm) fit typical battery compartments of Class I and Class II electric forklifts. Weight is 980kg; ensure the forklift is rated for this battery weight.

BMS Protection Features
The integrated Battery Management System provides comprehensive protection: individual cell overvoltage (3.65V cutoff), individual cell undervoltage (2.5V cutoff), overcurrent during charge and discharge, short circuit protection, high temperature cutoff at 65°C, and low temperature charging block (requires heater). The BMS also balances cells during charging to maximize capacity and extend life.

Cycle Life and Longevity
Although the PDF does not specify cycle count, typical LFP forklift batteries of this class provide 3000 to 5000 cycles at 80 percent depth of discharge. This translates to 5 to 8 years of daily single shift operation or 3 to 5 years of double shift operation. Compared to lead acid which lasts 500 to 1000 cycles, the lithium battery pays for itself through reduced downtime, no watering labor, and lower energy consumption (about 20 percent less energy per cycle).

Safety and Environmental Benefits
LiFePO4 chemistry is the safest lithium technology with no thermal runaway risk. The battery contains no lead or acid, eliminating hazardous waste disposal issues. It produces no hydrogen gas during charging, so no special ventilation is required. The maintenance free design reduces worker exposure to corrosive acids.

Warranty and Certifications
Standard warranty is typically 5 years for forklift lithium batteries. Certifications include UN38.3 for transport, CE, RoHS, and IEC 62619 for industrial vehicle batteries. The manufacturer provides technical support and spare parts.
