BSLBatt ECO 51.2V 100Ah Lithium Battery

The BSLBATT ECO 51.2 V 100 Ah offers a robust, safe, and scalable energy storage solution with around 5.12 kWh of nominal capacity per module. Its LiFePO₄ chemistry, strong power capability, and modularity make it suitable for modern home solar storage or backup systems.

Key Specifications

• Nominal voltage: 51.2 V

• Nominal capacity: 100 Ah ⇒ ≈ 5.12 kWh rated energy. 

• Usable capacity (depending on configuration) typically ~4.6 kWh as specified in some modules. 

• Chemistry: Lithium Iron Phosphate (LiFePO₄) — known for safety and durability. 

• Max continuous discharge current: ~100 A (≈ 5.12 kW) for one module.

• Max continuous charge current: ~80 A (≈ 4.1 kW) for one module.

• Cycle life: Over 6,000 cycles at 25°C claimed for some modules in this voltage series.

• Designed for modular expansion: Up to ~63 units in parallel in certain rack-mount designs (yielding up to ~322 kWh).

• Protection / enclosure: IP20 rated for the rack unit version; natural ventilation design.

• Warranty: 10 years (for certain models) in rack / server-battery versions.

Highlight Features & Benefits

• Safety & chemistry: The LiFePO₄ chemistry provides enhanced thermal and chemical stability compared to many other lithium-chemistries. According to the manufacturer, the product is built with safety by design. 

• High power capability: With the ability to discharge at ~1C (100A @100Ah) and charge at ~0.8C (80A), it’s well suited for both backup power and solar storage applications where moderate to high power draw is needed.

• Scalable / modular: If you only need ~5 kWh, one module is sufficient; if you require much larger capacity (for e.g. home energy storage or commercial ESS), you can stack multiple modules in parallel.

• Flexible installation: The product is described in rack-mount format (3U or 4U heights) and is capable of being wall mounted, floor mounted, or used in standard 19” racks.

• Good value “ECO” model: As the “ECO” variant, the idea is to deliver the high performance of the 51.2 V 100 Ah module family at a more economical price. (A social-media post mentions “Introducing the new BSLBATT ECO 51.2 V 100Ah! … the same 5.12kWh capacity you love at a more economical price!”)

• Low self-discharge and long life: The datasheet claims very low self-discharge (<3%/month) and design life >15 years at 25°C.

Typical Applications

• Home energy storage system (solar PV + battery) — storing excess solar energy during the day for use in the evening/night

• Off-grid or hybrid systems

• UPS / telecom backup power systems

• Rack-mounted systems in commercial/industrial settings, owing to the 19″ rack compatibility and modular design

• Any system requiring 48-V nominal (since 51.2 V is often used interchangeably with 48 V nominal systems) storage with LiFePO₄ chemistry
