Felicity 5kWh 48v Lithium Battery Pack With BMS

The Felicity 5kWh 48V Lithium Battery Pack with a Battery Management System (BMS) is a high-performance energy storage solution commonly used for solar energy systems, backup power, and off-grid applications. Here are some key features and specifications often associated with this type of battery pack:

Key Features

1. Capacity and Voltage: 5kWh capacity with a 48V output, ideal for medium-sized energy storage setups.
2. Lithium-Ion Technology: Provides a high energy density, making it lightweight compared to traditional lead-acid batteries and allowing it to store more energy in a compact design.
3. Battery Management System (BMS): Built-in BMS monitors the battery's health, ensuring protection from overcharging, over-discharging, and short circuits. It also helps in balancing cells and extending the battery’s lifespan.
4. Cycle Life: Typically rated for over 3,000 cycles at 80% depth of discharge, which can translate to around 10 years of usage, depending on the application.
5. Efficiency: Lithium batteries offer high charging and discharging efficiencies (typically over 95%), allowing for quick energy recovery and optimal performance.
6. Temperature Resistance: Often designed to operate in a wide temperature range, with BMS managing the temperature to prevent overheating.
7. Maintenance-Free: Unlike lead-acid batteries, lithium-ion batteries require minimal maintenance, making them cost-effective in the long run.
8. Scalability: Many models allow for connecting multiple units in parallel, providing increased storage capacity as energy needs grow.
