25.6V 100Ah LiFePO4 Battery Pack for Inverter

Product Overview & Features

The 25.6V 100Ah LiFePO4 Battery Pack for Inverter is a rechargeable lithium iron phosphate energy-storage battery designed for compatible inverter, solar backup and stationary power applications. With a nominal voltage of 25.6V and a rated capacity of 100Ah, the battery provides a nominal stored-energy capacity of approximately 2.56kWh (2560Wh). This value is consistent with the specification printed on the product and with standard 25.6V/100Ah LiFePO4 battery-system calculations. Renogy

The battery uses LiFePO4 (Lithium Iron Phosphate/LFP) chemistry, a lithium-ion chemistry widely used in energy-storage applications where repeated charge and discharge operation is required. The product label identifies it specifically for solar inverter use and states that a Battery Management System (BMS) is built into the battery.

An integrated BMS is an important part of a lithium battery system because it manages battery operation and helps keep the cells within appropriate electrical operating limits. The exact protection thresholds, maximum charge current and maximum continuous discharge current for this particular battery should be taken from its approved technical specification rather than assumed from batteries of similar capacity.

The battery is housed in a substantial enclosed casing with an integrated carrying handle and insulated positive and negative power leads/connectors. This construction is suitable for installation as a dedicated inverter battery where dependable DC energy storage and convenient electrical connection are required.

Technical Performance & Engineering Details

The 25.6V nominal system voltage places this battery in the commonly used 24V-class lithium battery category. A 25.6V 100Ah LiFePO4 battery corresponds to 2560Wh or 2.56kWh of nominal stored energy:

25.6V × 100Ah = 2560Wh

Independent technical documentation for 25.6V 100Ah LiFePO4 battery systems also identifies this combination as a 2560Wh energy-storage configuration. Renogy

This does not mean that every inverter can use the battery automatically. The inverter or inverter-charger must support the voltage and charging requirements of a 25.6V LiFePO4 battery system. Charging parameters should be configured according to the battery manufacturer's approved limits rather than by applying lead-acid charging settings without verification.

The built-in BMS shown on the product labeling provides battery-management functionality. BMS systems are commonly used in LiFePO4 batteries to supervise charging and discharging conditions, although the exact protection functions and threshold values vary by battery design. For this reason, specific claims such as maximum discharge current, short-circuit threshold, temperature cut-off, balancing current or communication functionality should not be stated unless they are confirmed for this exact pack.

LiFePO4 batteries are widely used for inverter and energy-storage systems because the chemistry supports repeated cycling and does not require the routine electrolyte maintenance associated with conventional flooded lead-acid batteries. Appropriate charging, installation and operating conditions remain essential for battery life and performance.

Applications

• Solar inverter battery systems

• Home and commercial power-backup systems

• Compatible 24V-class inverter installations

• Solar energy-storage systems

• UPS and stationary backup applications where electrical specifications are compatible

• Off-grid and renewable-energy storage installations

• DC energy-storage systems designed for 25.6V LiFePO4 batteries

Installation Guide

Install the battery only with an inverter, charger or inverter-charger that supports the electrical requirements of a 25.6V LiFePO4 battery.

Before connection, confirm correct positive and negative polarity and ensure all connections are secure. Use appropriately rated cables, connectors, protection devices and isolation equipment according to the system current and installation requirements.

The battery should be installed in a dry, protected and adequately ventilated location away from direct heat sources, excessive moisture and conditions that may physically damage the enclosure or cables.

Do not select charging voltage, charging current or inverter low-voltage cut-off values based solely on another 24V battery model. These parameters should follow the approved specification of this particular battery pack.

If multiple batteries are to be connected in series or parallel, confirm that this exact model is approved for that configuration before making the connection. Series or parallel capability should not be assumed.

Specifications

I have not added a maximum charging current, maximum discharge current, charging voltage, cycle-life figure, operating-temperature range, battery weight, exact dimensions, BMS current rating, cell grade, series/parallel limit, IP rating or communication protocol because none of those can be confirmed from the photographs you provided. Similar 25.6V LiFePO4 batteries have different values for these specifications, so borrowing them from another manufacturer's 100Ah battery would reduce the accuracy of your listing.

The product photographs do support 25.6V, 100Ah, 2560Wh, LiFePO4/LFP, solar-inverter application and built-in BMS. Your side photograph also visibly carries a 60-month warranty graphic, but I have not included a 60-month warranty promise in the customer-facing copy because warranty terms should be confirmed against ARB's actual sales policy before publication.
