Description

A 25.6V 100Ah LiFePO4 (Lithium Iron Phosphate) battery is a high-density energy storage solution equivalent to 2.56kWh of power. This “Heavy Duty” configuration is typically used as a 24V nominal system for solar storage, large-scale UPS backups, and marine applications.

## Core Specifications

## Charging & Discharging

• Charge Voltage: 28.4V – 29.2V (Max 29.2V)

   

• Discharge Cut-off Voltage: 20.0V – 23.0V (depending on BMS settings)

• Standard Charge Current: 20A – 50A

   

• Max Continuous Discharge Current: 100A (Allows for a ~2,500W load)

   

• Peak Discharge Current: 200A – 300A (typically for 1–3 seconds to handle motor surges)

## Heavy-Duty Features

• Integrated BMS (Battery Management System): This is the “brain” of the battery. In a heavy-duty model, it protects against:

   

  • Over-charging and Deep-discharging.

     

  • Over-current and Short circuits.

     

  • Thermal Runaway: High-temperature sensors shut down the battery if it overheats.

     

• Cold Weather Protection: Many heavy-duty variants include a “low-temperature cut-off” to prevent charging below 0°C, which can damage lithium cells.

   

• Prismatic Cells: Uses large, rectangular prismatic cells (rather than hundreds of small cylindrical ones) for better thermal stability and mechanical durability.

• Parallel/Series Capability: Designed to be connected with identical units to expand capacity (Parallel) or increase voltage to 48V (Series, if supported by the specific BMS).

   

## Why Choose LiFePO4 over Lead-Acid?

Efficiency Advantage: While a lead-acid battery only provides about 50% usable capacity without damage, a LiFePO4 battery can safely use 90% to 100% of its 100Ah rating. This means a single 100Ah Lithium battery often replaces two 100Ah Gel/Lead-Acid batteries.

## Ideal Applications

• Off-Grid Solar: Storing energy for 24V inverter systems.

   

• Electric Mobility: Golf carts, forklifts, or trolling motors.

• Backup Power: Critical home or office loads during power outages.
