Overview
The CMX 51.2V 660Ah LiFePO4 Battery for Mini Forklift and Electric Vehicle is a drop-in lithium iron phosphate (LiFePO4) power pack engineered for small electric forklifts, walkie stackers, pallet trucks, and light electric vehicles. Rated at 51.2V (16-series LiFePO4) with a 660Ah capacity, it delivers about 33.8 kWh of usable energy in a sealed, space-saving enclosure that replaces bulky, high-maintenance lead-acid batteries without changing the compartment or charger footprint in most applications.
CMX builds the pack from automotive-grade LiFePO4 cells and a self-developed smart BMS. The result is a battery that stays balanced, runs cool, and is protected across its whole service life — so operators get flat voltage through discharge, fast opportunity charging, and far less downtime than lead-acid.
Key Features
- Drop-in lead-acid replacement — same nominal voltage and a compact form factor that fits standard mini-forklift and pallet-truck battery compartments; 100% usable capacity with no watering, equalizing, or acid handling.
- Long service life — 3,500+ cycles at 80% depth of discharge, far beyond the 500–1,000 cycles typical of lead-acid, lowering the cost per cycle over the equipment’s life.
- Smart BMS with full protection — over-voltage, under-voltage, over-current, short-circuit, and over/under-temperature protection plus automatic cell balancing keep every cell within safe limits.
- Fast & opportunity charging — supports opportunity charging during breaks, removing the long equalize cycles lead-acid requires and extending daily uptime.
- Flat discharge curve — LiFePO4 holds voltage near nominal through most of the discharge, so the forklift or EV keeps full power until the pack is nearly empty.
- Built for industrial use — sealed, vibration-resistant enclosure, low self-discharge, and stable output from cold-start to high-temperature operation, with low-temperature charging protection.

Application Scenarios
The 51.2V 660Ah LiFePO4 pack is purpose-built for electric material-handling and light electric-mobility equipment, including:
- Mini forklifts & walkie stackers — direct lead-acid replacement for small warehouse and retail forklifts that run multiple shifts.
- Electric pallet trucks & tow tractors — a compact, low-weight pack that improves maneuverability while extending run time per charge.
- Low-speed electric vehicles — neighborhood EVs, electric utility carts, and groundskeeping vehicles needing a safe, maintenance-free 51.2V power source.
- AGV & automated guided vehicles — stable, fast-charging power for automated warehouses and production lines.
- Electric golf carts & airport / campus tugs — reliable daily-service energy with opportunity charging between runs.
Because it is a 51.2V LiFePO4 system with a protected smart BMS, the pack is also a strong base for custom OEM/ODM electric-vehicle and material-handling projects — see our forklift & AGV LiFePO4 OEM guide or contact CMX to size a configuration for your equipment.

CMX Battery offers dealer customers a 10-year warranty and technical service for its energy storage battery products.
DoD describes how much of the battery's capacity has been used. A DoD of 100% means the battery is completely empty, while 0% means it is full.
SoC reflects the battery's charge level. A SoC of 100% means the battery is full, and 0% means it is empty.
C-rate, or power factor, indicates how quickly a battery can be charged or discharged relative to its capacity. A rating of 1C means the battery can be fully charged or discharged in one hour.
The battery uses Lithium Iron Phosphate chemistry and provides a cycle life of over 6,000 cycles at 90% Depth of Discharge, and over 10 years at one cycle per day.
kW (kilowatt) is a unit of power, measuring the rate of energy production or consumption. kWh (kilowatt-hour) is a unit of energy, measuring the total amount of work done or energy used over time.
CMX Battery home batteries are suitable for both indoor and outdoor installation (depending on the model's protection level) and offer floor-standing or wall-mounted options. Common locations include garages, attics, or under eaves.
This depends on the load. As a realistic example, a 10kWh battery could run ten 100-watt light bulbs for 12 hours without recharging.
The number varies based on home size, energy consumption history, and personal goals (like which devices to run during an outage). For most systems, 2 or 3 batteries are installed. A detailed discussion of your needs is recommended for an accurate assessment.
Yes, it is possible, but it requires careful planning and significant investment. A true off-grid system needs a large enough solar array and sufficient battery storage to sustain your lifestyle. Cost and having an alternative energy source for when solar charging isn't possible are key considerations.
No. CMX Battery focuses on building long-term relationships with business partners like battery distributors, solar equipment dealers, and installation contractors worldwide, not direct sales to end consumers.
