The FLB-80500S is an 80V 500Ah LiFePO4 forklift battery pack designed for heavy-duty electric forklifts, warehouse trucks, port logistics equipment, cold storage vehicles, and lead-acid replacement projects.
With approximately 40.0kWh rated energy, smart BMS protection, CAN / RS485 communication options, and customizable enclosure design, this battery system supports stable power delivery, reduced daily maintenance, and efficient charging for industrial material handling applications.

The FLB-80500S is built for industrial users who need a reliable lithium battery solution for electric forklifts and material handling equipment. Compared with traditional lead-acid batteries, LiFePO4 forklift batteries can help reduce watering, acid maintenance, long charging downtime, and frequent battery replacement.
This battery pack is suitable for heavy-duty forklift platforms where energy capacity, stable discharge, safety protection, charger matching, connector selection, and mechanical fit are all important. The final configuration can be adjusted according to forklift model, battery tray size, counterweight requirements, operating temperature, duty cycle, and communication needs.
The 80V 500Ah configuration provides strong energy support for heavy-duty forklifts, warehouse vehicles, and multi-shift material handling operations.
LiFePO4 chemistry offers stable thermal performance, long cycle life, and lower routine maintenance compared with lead-acid forklift batteries.
The integrated BMS monitors cell voltage, pack current, temperature, SOC, SOH, fault status, and cell balance to support safer charging and discharging.
High-current charging can be configured according to charger power, connector rating, cable size, BMS settings, and thermal design.
Communication interfaces can be customized for compatible forklift controllers, chargers, displays, or fleet management systems.
Battery enclosure size, weight, mounting layout, cable outlet position, connector type, and service access can be customized for forklift tray installation.
