Designed for gardening enthusiasts and professionals, this device offers you complete weather monitoring and graphical forecasts for the next 24 hours. Its compact and modern design fits perfectly into any outdoor or indoor environment.

Double your autonomy while maintaining the same reliability.
This pack combines 2 identical LiFePO4 48 V 50 Ah batteries to achieve 5.12 kWh of available energy at 51.2 V, with an integrated BMS in each unit and a robust metal case for better heat dissipation.

Key points

• Total pack energy: 5,120 Wh
• Native parallel assembly: 2 units → 51.2 V / 100 Ah
• Integrated safety: overvoltage, undervoltage, overcurrent, temperature, short-circuit protections (BMS per battery)
• Metal case: designed to withstand and better dissipate heat
• Pack weight: ~ 53 kg (2 × 26.5 kg)
• Compact format: easy to fit in a van, technical room, or battery box

Ideal for

• Residential solar systems and isolated sites
• Motorhomes, converted vans, caravans
• Boats and marine installations
• Backup power / continuity of activity (workshop, small business)
• Autonomous lighting, small low-voltage electric vehicles

Pack contents

• 2 × Lithium LiFePO4 48 V 50 Ah Battery (same model, same series)
• Connection terminals with M8 screws (on each battery)

Characteristics of the pack (2× in parallel)

• Nominal voltage (pack): 51.2 V
• Capacity (pack): 100 Ah
• Energy (pack): 5,120 Wh
• Recommended continuous current: distributed ≤ 50 A per battery (up to 2× if perfectly balanced wiring)
• Recommended topology: parallel only (same cables, same lengths, same section)

Good to know: the total current of a parallel setup is distributed among the batteries. Use a busbar (distribution bar) and individual fuses for each battery for clean current sharing.

Characteristics of a battery (unit)

• Capacity: 50 Ah
• Energy: 2,560 Wh
• Nominal voltage: 51.2 V
• Max. charge voltage: 58.4 V
• Max. charge/discharge current: 50 A
• Charge temperature: 0 → 55 °C
• Discharge temperature: −30 → 55 °C
• Connectivity: M8 terminals
• Dimensions (L×W×H): 437 × 333 × 125 mm
• Weight: 26.5 kg
• Chemistry: LiFePO4
• Electronic management: BMS with overvoltage / undervoltage / overcurrent / short circuit / temperature protections

Compatibility & installation advice

• 48 V regulators/inverters: compatible (48 V battery input).
• Parallel only: do not connect in series unless explicitly instructed by the manufacturer.
• Symmetrical wiring: same lengths and same sections between each battery and the busbar.
• Protection: provide a fuse or circuit breaker per battery on the positive side.
• Initial balancing (recommended): charge both batteries to 100% before connecting them in parallel.
• Do not mix new/old batteries or different models.

Why this pack?

• More autonomy, same footprint: switch to 5.12 kWh without modifying your system's architecture.
• Safety and longevity: LiFePO4 + BMS = several thousand cycles under good usage conditions.
• Simple maintenance: no memory effect, low self-discharge, durable metal casing.
