Nominal and Estimated Usable Energy — Per Battery

Nominal energy: 3.789 kWh, as listed in the product manual. Estimated usable energy: approximately 3.600 kWh (3.789 × 95% = 3.59955 kWh), using ROCKSOLAR’s catalog estimate where no manufacturer-stated usable-energy figure is supplied. This is not a tested or guaranteed usable-energy rating and is before conversion losses.

Routine discharge guidance: The manual separately recommends discharging about 80% of nominal capacity for longevity—approximately 3.031 kWh per battery. The 95% catalog estimate does not override that operating guidance. Multi-unit options contain separate batteries and must not be connected in series or parallel.

🧠 Smart BMS Protection

Built-in Battery Management System (BMS) provides complete protection, including:

• Over-charge / Over-discharge protection
• Over-current and short-circuit protection
• Temperature control (high & low)
• Cell balancing for optimal performance

🌿 Advantages of LiFePO4 Technology

• Up to 4× longer lifespan than lead-acid batteries
• Lightweight design (≈ 50% less weight)
• Safe, non-toxic, and environmentally friendly
• High efficiency and stable voltage output
• Maintenance-free and deep cycle ready

🚙 Ideal Applications

• Solar energy systems & off-grid power
• RVs and campers
• Marine and boat power storage
• Golf carts and electric vehicles
• Energy backup and industrial equipment

🧩 Charging & Maintenance

• Use a compatible LiFePO4 charger (57.6 V constant voltage charging)
• Charge within 24 hours after full discharge
• Store at 15–25 °C in a dry environment (40–60% SOC recommended)
• Regular maintenance charge every 2 months to avoid over-discharge

🔧 Safety & Handling Cautions

• Do not short-circuit or reverse polarity
• Do not expose to fire or immersion in water
• Install in a well-ventilated area, away from direct sunlight
• Clean with a dry cloth only — avoid solvents or oil
• Use only approved chargers and connectors

📦 Package Options and Connection Restriction

The selected option supplies one, two, three, or four separate batteries. Multi-unit options are quantity packs, not a combined battery bank. The product manual prohibits connecting these battery packs in series or parallel. Use each battery independently with compatible equipment.
