48v Bms 10KWH LiFePO4 Battery

5/10KWH Power Wall Batteries

Power & Capacity Performance: Operating at a nominal 48V (range: 45V–57.6V), this 10kWh battery provides steady power for a range of applications. It can easily handle 2–3kW loads, such as powering a small business's lights, computers, and a 1.5kW fridge during a grid outage for 5–10 hours, or supporting an off-grid home's essential appliances overnight. It supports a continuous discharge current of 50A, with peak surges up to 200A, making it adaptable to high-demand devices like air conditioners or power tools. Its stable voltage output protects sensitive equipment, including solar inverters and smart home systems.

Safety & Longevity: The integrated BMS offers comprehensive protection, including overcharge cutoff at 57.6V to prevent cell damage, over-discharge prevention below 45V to extend lifespan, and safeguards against overcurrent (100A max) and short circuits. It regulates temperature from -20°C to 60°C, with automatic shutdown at 65°C to avoid overheating in hot climates. Active cell balancing ensures uniform charge across 16 series-connected lithium cells (3.2V each), preventing uneven aging and maintaining consistent performance over time. Combined with lithium chemistry, this results in 5,000+ deep cycles at 80% depth of discharge-far exceeding lead-acid's 300–500 cycles-with a 12–15 year lifespan and zero maintenance (no need for watering or acid checks).

Design & Durability: Housed in a fire-retardant, IP65-rated casing, the battery resists dust, moisture, and vibration, making it suitable for indoor, garage, or covered outdoor installations (e.g., alongside solar panels). Its compact dimensions (approximately 600×300×600mm) and weight of ~75kg save 50–60% space compared to lead-acid equivalents, fitting easily in utility rooms, industrial cabinets, or small storage areas. Built-in lifting handles simplify installation, while a clear LCD display shows real-time state of charge (SOC), voltage, and current, eliminating guesswork about remaining power.

Efficiency & Compatibility: With 94% round-trip energy efficiency, it minimizes energy loss during charging and discharging-significantly outperforming lead-acid batteries (80% efficiency) and reducing reliance on generators or grid power. It integrates seamlessly with MPPT solar charge controllers (e.g., Victron, SMA) and 48V inverters via standard terminals, supporting both off-grid solar setups and grid-tied backup systems. Optional RS485/Bluetooth connectivity enables remote monitoring via smartphone apps, allowing users to track energy usage, receive alerts for low charge, or adjust settings-adding convenience for smart energy management and centralized oversight.
