Pack of 2 Rackable Lithium Batteries 48 V 100 Ah – 10.24 kWh LiFePO4, Bluetooth & Wi-Fi

Discover the professional anemometer, the ideal tool for accurately measuring wind speed, temperature, and air humidity, both outdoors and indoors. 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 energy reserve, without complicating the installation. This pack brings together 2 rack modules 48 V / 100 Ah (5.12 kWh each) to constitute 10.24 kWh in total, ready to operate in parallel on a domestic, solar, or hybrid 48 V installation.

The essentials to remember

• 10.24 kWh usable to significantly increase autonomy (2 × 5.12 kWh).
• 19" rack format: clean integration in the bay, vertical mounting possible.
• Plug & play: simple parallel connection, scalable up to 15 modules in parallel.
• Real-time monitoring via Bluetooth & Wi-Fi + RS485 / RS232 / CAN bus.
• Integrated safety: 100 A BMS per module, 125 A circuit breaker, complete protections.
• Longevity: Grade A cells, up to 15,000 cycles, 10-year warranty.

Why a pack of 2?

• Autonomy x2 without redoing all the wiring: add a second identical module in parallel to double the energy reserve.
• Ease of use: fewer deep cycles daily → increased lifespan.
• Scalable: you can add more modules later (up to 15 in parallel).
• Optimized budget & space: rack format, quick implementation, facilitated maintenance.

Supervision & connectivity

• Mobile app (BT/Wi-Fi): voltage, state of charge (SOC), current, remaining capacity… for each module.
• Interfaces: RS485, RS232, CAN for communication with common hybrid inverters in France (e.g., Victron, Growatt…).
• Multi-module management: view information per battery and manage your fleet precisely.

Safety & reliability

• 100 A BMS per module: cell balancer, overvoltage / overcurrent / short circuit / overheating protections.
• 125 A circuit breaker and On/Off switch integrated.
• Low temperature protection: charge blocking < 0 °C (discharge possible down to -20 °C).
• Grade A cells: stable performance, low self-discharge.

Typical integration

• Usage: self-consumption, off-grid, home backup, micro-grid.
• Principle: charging during off-peak hours/PV production, use during consumption peaks.
• Wiring: parallel connection between modules (identical voltages) then connection to the 48 V inverter/regulator according to the manufacturer's documentation.

Package contents (pack of 2)

• 2 × 48 V 100 Ah lithium batteries in rack format
• Cable set(s) for parallel connection and communication cables

Installation tips

• Use cables of the same section and length between modules and to the inverter.
• Before paralleling: check that both modules are at the same SOC (± 2%).
• Parallel only (no series mounting, unless explicitly specified by the manufacturer and inverter compatibility).
• Set the inverter/controller according to LiFePO4 48 V (e.g., 58.4 V max charge, float and low voltage cut-off values as per the manual).
• Provide ventilation and secure in rack or stable vertical position.

2-year warranty
