51.2V 50Ah Deep Cycle Lithium Battery 51.2V 50Ah for Automated Guided Vehicles

Product Overview
This 51.2V 50Ah lithium iron phosphate battery is specifically designed for Automated Guided Vehicles (AGVs), robotic trolleys, and industrial mobile equipment. With 2560 watt hours of energy and over 4000 deep cycles at 80 percent remaining capacity, it provides the long lasting power that AGV fleets require for continuous daily operation. The built in Battery Management System ensures safe charging, discharging, and cell balancing while communicating directly with the vehicle’s controller via RS485 or CAN bus.

Parameters

Why AGVs Need This Battery
AGVs operate on demanding schedules, often running multiple shifts and opportunity charging during brief stops. Traditional lead acid batteries require long cooling and watering cycles, causing downtime. This LiFePO4 battery supports fast charging at up to 50A and can be opportunity charged without reducing cycle life. The low weight of 29kg improves vehicle efficiency and payload capacity compared to lead acid alternatives. The maintenance free design eliminates acid leaks and watering tasks in automated warehouses.

Key Technical Specifications for AGV Integration
Nominal voltage is 51.2V with 50Ah rated capacity. Continuous discharge current is 50 amps, sufficient for AGV drive motors, lifting decks, and onboard computers. Pulse discharge current reaches 150 amps for less than one second, covering startup surges and momentary acceleration. Internal resistance stays below 35 milliohms for efficient power delivery. Efficiency is 98 percent. Dimensions are 420 by 360 by 130 millimeters, fitting standard AGV battery compartments. The SB50A terminal provides a secure high current connection resistant to vibration. Housing is SPCC steel with IP65 dust and water jet protection, suitable for warehouse floors with occasional water washdown.

BMS Communication and AGV Control
The battery communicates over RS485 and CAN protocols, allowing the AGV’s main controller to read real time data including state of charge, voltage, current, temperature, cycle count, and fault status. This data enables predictive route planning, battery swapping alerts, and safe shutdown before low voltage cutoff. The BMS can be configured to send warnings when charge drops below a user set threshold, preventing unexpected vehicle stops in the middle of an aisle.

Discharge Parameters for AGV Duty Cycles
Standard discharge current is 50A continuous. BMS discharge cut off voltage is 40V and reconnect voltage is 43.2V. Short circuit protection triggers in 300 to 800 microseconds, protecting both the battery and the AGV’s motor controllers. The battery supports high frequency partial charge and discharge without memory effect, making it ideal for AGVs that recharge at every opportunity.

Charge Parameters for Opportunity Charging
AGVs typically recharge during short idle periods at charging stations. This battery accepts CC CV charging with voltage between 56.8V and 58.4V. The recommended charge current is 25A for maximum cycle life, but the maximum allowable current is 50A for faster top ups. BMS charge cut off voltage is 58.4V. The battery can be charged multiple times per day without degradation, a critical requirement for 24/7 logistics operations.

Temperature Performance in Warehouse Environments
Warehouses can be cold storage or hot loading docks. This battery discharges reliably from -20°C to 60°C, covering freezer zones and summer heat. Charging is allowed from 0°C to 55°C. Below freezing, the BMS blocks charging to protect cells. Storage temperature is -20°C to 35°C. BMS high temperature cut off is set at 65°C, adding a safety layer for unattended charging.

Cycle Life and Total Cost of Ownership
The battery delivers more than 4000 cycles at 100 percent depth of discharge while retaining over 80 percent of original capacity. For an AGV that completes two full cycles per day, this represents over five years of service before reaching 80 percent remaining capacity. In comparison, a lead acid AGV battery typically lasts 500 to 800 cycles under similar opportunity charging conditions. The higher upfront cost of lithium is recovered within two years through reduced downtime, no watering labor, longer life, and lower energy consumption.

Physical Integration and Safety for AGVs
The IP65 rating protects against dust ingress and low pressure water jets, making the battery safe for food and beverage warehouses where floor washing is frequent. The SPCC steel housing is impact resistant and includes internal cell cushioning against vibration. The SB50A connector is locking type to prevent accidental disconnection during vehicle motion. The battery includes a handle for manual lifting during maintenance or replacement.

Applications Beyond AGVs
While designed for AGVs, this battery also serves automated mobile robots (AMRs), autonomous forklifts, electric pallet jacks, floor scrubbers, and heavy duty automated guided carts. It can be used as a drop in replacement for 48V lead acid batteries in existing industrial vehicles, provided the vehicle controller supports lithium communication or can operate with voltage only mode.

Installation Notes for AGV Manufacturers
Mount the battery securely in a compartment with airflow for cooling. The IP65 rating allows outdoor use but avoid direct water jet impingement on the connector. Use cables rated for 50A continuous current with SB50 compatible plugs. Connect the RS485 or CAN wires to the vehicle’s communication bus using twisted pair shielded cable. Configure the BMS communication parameters to match the AGV’s protocol (default is CAN 250kbps or RS485 Modbus RTU). For more than one battery in parallel, consult the manufacturer because this model is rated for 1P only.

BMS Safety Features for Unattended Charging
AGVs often charge automatically without human supervision. The BMS provides six layers of protection. Overcharge protection stops charging at 58.4V. Over discharge protection cuts output at 40V. Over current protection limits both charge and discharge to 50A continuous. Short circuit response is faster than most external fuses. Temperature monitoring disconnects at 65°C. Cell balancing activates during charging to keep series cells within 20mV difference. These features certify the battery for unattended operation in industrial environments.
