Athena Wall-Mounted Battery 2.5kWh (25.6V/100Ah) - Athena A series product image
The Athena Wall-Mounted Battery 2.5kWh (model SCAE-A-25.6-100) is a compact 25.6V 100Ah LiFePO4 battery designed for installers and homeowners who already own a hybrid inverter and need a space-saving, wall-mountable energy storage module. Delivering 2560Wh from a 36 by 19.5 by 42 centimeter enclosure, this entry-level Athena A unit uses BAK 100Ah prismatic cells and a 100A discharge current, making it suitable for small solar self-consumption systems, caravan and marine retrofits, and lightweight backup applications. The wall-mount bracket means the battery can be installed in a garage, utility room, or equipment shed without consuming floor space, and the standardized 25.6V nominal voltage pairs with a wide range of third-party hybrid and off-grid inverters. CMJ Solar's LiFePO4 chemistry provides 2000 to 4000 charge-discharge cycles, far exceeding lead-acid longevity, and the unit is covered by a 5-year warranty with CE, UN38.3, and MSDS certifications. For distributors building custom solar kits, the Athena A 2.5kWh is an easy-to-spec building block that can be paralleled for higher capacity. CMJ Solar manufactures in Jiangmen, Guangdong and offers wholesale pricing, OEM labels, and container shipping. Visit cmjsolar.com for distributor pricing.

Product Overview

Is the SCAE-A-25.6-100 the Right Capacity for You?

Best suited for

The Athena A 25.6V 100Ah is a 2.5kWh wall-mounted battery in a compact 36 by 19.5 by 42 centimeter enclosure, designed to pair with an external 24V hybrid inverter for small solar and backup systems.

Typical loads this capacity handles

Through a matched 24V inverter it supports small-home essential loads such as lighting, internet, electronics, and a fridge for part of the evening. The 100A discharge at 25.6V covers roughly 2.5kW on the DC side; it is a battery only and does not include an inverter.

Estimated runtime

Runtime example: about 2.3kWh usable. After inverter losses, a 300W load runs for roughly 7 hours and a 150W load around 13 hours; DC-only 24V loads run slightly longer.

Sizing advice

Pick the 25.6V 100Ah for space-constrained 24V systems and confirm the hybrid inverter and charge controller are genuinely 24V before ordering. For full-night household backup, the 51.2V models provide a more typical residential voltage and capacity.

Frequently Asked Questions

What warranty does this product come with?

The Athena Wall-Mounted Battery 2.5kWh (25.6V/100Ah) comes with a 5-year warranty covering the LiFePO4 battery cells and integrated BMS. Our LiFePO4 cells are rated for 2,000-4,000 charge-discharge cycles, providing 5-10 years of reliable daily use under normal operating conditions. Spare parts and technical support are available throughout the warranty period.

What is the MOQ (Minimum Order Quantity)?

The MOQ is typically 20 units per model for standard products. Sample orders of 1 unit are welcome for testing and evaluation. For OEM/ODM custom packaging or private labeling, the MOQ is 500 units. Contact our sales team for specific pricing based on your order volume.

How long can the Athena Wall-Mounted Battery 2.5kWh (25.6V/100Ah) power my home during an outage?

The Athena Wall-Mounted Battery 2.5kWh (25.6V/100Ah) provides 2,560Wh of stored energy (approximately 2,304Wh usable at 90% depth of discharge). At an average essential-load draw of 500W (lights, router, refrigerator, and TV), it can sustain power for approximately 4.6 hours. At 1,000W, runtime is approximately 2.3 hours. Actual runtime depends on total connected load and usage patterns.

How is the wall-mounted battery installed?

The Athena Wall-Mounted Battery 2.5kWh (25.6V/100Ah) features a compact wall-mounted design suitable for garages, utility rooms, and indoor installations. It mounts to a solid wall using the included wall bracket and hardware. The 25.6V LiFePO4 battery connects to a compatible hybrid inverter via the included communication cables. Professional installation by a certified electrician is recommended. The wall-mounted form factor saves floor space compared to floor-standing cabinets.

How long does the LiFePO4 battery last?

The LiFePO4 cells in the Athena Wall-Mounted Battery 2.5kWh (25.6V/100Ah) are rated for 2,000-4,000 charge-discharge cycles before capacity drops to 80% of the original rating. In a typical daily-cycle residential application, this translates to 5-10 years of service life. LiFePO4 chemistry also offers superior thermal stability and safety compared to lead-acid or NMC batteries, with no maintenance required.
