Product Features
Smart 100A BMS Protection
Built-in intelligent 100A BMS (Battery Management System) provides overcharge, over-discharge, overcurrent, short circuit, and extreme temperature protection. It supports high-rate discharge, is compatible with mainstream inverter brands, and ensures the operational stability of off-grid and hybrid power systems.
Massive Scalability (Up to 20.48kWh)
Supports up to 4 series 4 parallel (4S4P) expansion, allowing for flexible construction of battery packs from 12V to 48V. This modular design significantly enhances system integration flexibility, catering to diverse requirements ranging from RVs to residential energy storage projects.
50% Weight Reduction and Space-Efficient
Boasting an energy density of up to 1280Wh, the unit weighs only one-third as much as a lead-acid battery of equivalent capacity. Its compact structural design not only reduces international shipping costs but also facilitates rapid handling and installation at project sites, thereby boosting construction efficiency.
Industrial-Grade Certification & OEM Support
The product complies with international safety certification standards, including CE, UN38.3, and MSDS. As a factory direct supplier, we offer complete OEM/ODM customization services (including logo silkscreen printing, BMS parameter calibration, and shell color customization).

FAQ – 500kW / 1100kWh All-In-One Air-Cooled High-Voltage Energy Storage System
1. How does the return on investment (ROI) of 12.8V LiFePO₄ batteries compare to traditional lead-acid batteries?
Although the initial cost is higher, 12.8V LiFePO₄ batteries support 4,000 to 6,000 deep cycles, while lead-acid batteries only support 300 to 500 cycles. This means lithium iron phosphate batteries last over 10 times longer. Combined with minimal maintenance and higher energy density, the levelized cost of energy (LCOE) is about 70% lower than lead-acid batteries over the full lifecycle.
2. Can this battery be used in combination with existing lead-acid batteries?
Mixing them is not recommended. Because lithium batteries and lead-acid batteries have completely different charge-discharge characteristics and voltage profiles, mixing them can lead to battery damage or system failure.
3. What protection functions does the built-in BMS provide?
Our batteries include an industrial-grade Smart BMS that monitors cell status in real-time. It provides 6 core protections: Over-Charge Protection, Over-Discharge Protection, Over-Current Protection, Short-Circuit Protection, Temperature Protection, Auto-Balancing.
4. What is the maintenance frequency for long-term storage?
LiFePO4 has an extremely low self-discharge rate (1%-3% per month). For long-term storage:
Maintain the State of Charge (SOC) between 40% - 60%. To maintain cell health and BMS operation, we recommend a maintenance charge every 3 to 6 months.
5. Do you support custom prototypes? What is the Minimum Order Quantity (MOQ) for OEM orders?
We support sample testing. Standard OEM customization (such as private labeling the casing) typically involves MOQ requirements; please click [Contact Customer Service] to obtain specific customization plans and quotes.
