For small to medium-sized businesses (SMBs), such as retail stores or small data centers, space-saving and safe energy storage is key. Walmay’s FJ48100— a rack-mounted lithium iron phosphate (LFP) module—solves these needs.

What Is the Rack-Mounted LFP Battery Module?

A compact, rack-mounted energy module built for commercial/light industrial use, fitting standard 19-inch server racks.

Walmay Key specs:

Capacity & Power: 5.22kWh (102Ah LFP cells), 5kW max output—powers POS systems, small HVAC, or backup servers.

Size & Weight: 590×390×145mm, ~46.8kg—uses existing rack space, no extra floor room.

Safety: IP21 protection (dust/dripping water proof) + advanced BMS (prevents overcharge/overheat); LFP chemistry avoids thermal runaway.

Durability: >6000 cycles (90% DoD) = 8–10 years lifespan; CAN/RS485 for real-time monitoring.

What It Brings to Your Business：

1. Space Efficiency

Fits standard server racks—no new floor space needed. Stack up to 4 modules (20.88kWh total) for more capacity without clutter. Great for stores or offices short on space.

2. Cost Savings

Long Life: 6000+ cycles cut replacement costs by 70% vs. lead-acid batteries (2–3 year lifespan).

Low Maintenance: No water topping or electrolyte checks—BMS handles health monitoring.

Efficient: 90%+ efficiency in 0~55℃ (charge) / -10~55℃ (discharge)—less energy waste.

3. Reliable Backup

Triggers backup in milliseconds—faster than generators. 1 module powers critical gear (POS, small servers) for 1–2 hours; 3–4 modules extend to 6–8 hours. Avoids outage losses (e.g., lost sales, data loss).

4. Flexible Growth

Add modules as needs grow (e.g., new checkout lanes). Pair with small solar setups to store daytime energy—use at night to cut grid reliance.

Why Choose Walmay?

Corrosion-resistant casing (from Walmay’s steel expertise) handles indoor dust/moisture. 7×24 support across 50+ countries—fast help with installation/monitoring.

For SMBs, the Rack-Mounted LFP Battery Module delivers compact, cost-effective energy storage, keeping operations smooth without space or budget stress.
