Product Description

Core Advantages

1. Standardized cell platform, suitable for battery factory mass production and implementation

It is equipped with industry-standard 314Ah energy storage A-grade cells, with dimensions and electrical parameters that are common in the market. The battery factory does not need to re-mold and can quickly be compatible with its own cabinets and rack structures;

The 12.8V 4S standard voltage platform allows multiple groups to be connected in series to a 24V/48V high-voltage energy storage system, and there is no limit on the number of parallel connections, and it can flexibly match the customer's multi-voltage product line layout.

2. High-power stable output, 2000W continuous discharge without attenuation

Continuous 2000W support, strong peak short-time overload capacity, suitable for inverter impact start-up and synchronous operation of large power loads;

The voltage in the full discharge range is stable, without significant voltage drop, reducing the difficulty of downstream PCS debugging and improving the conversion efficiency of the energy storage system.

3. Active balancing BMS, reducing battery factory after-sales losses

It is equipped with a high-precision active balancing management system, with a single string pressure difference ≤ 0.02V, and the consistency of the cells is long-term stable;

It has six-level hardware protection for overcharge, overdischarge, overcurrent, short circuit, high temperature, and low temperature, and is fully inspected at the factory, significantly reducing the customer's failure rate of finished products and after-sales maintenance costs.

4. Inherent safety + dual-layer protection of the entire machine, ensuring energy storage compliance

The underlying lithium iron phosphate cells have strong thermal stability, combined with explosion-proof valves, flame-retardant V0-level enclosures, and independent insulation cavities; The entire machine passes puncture, compression, and abuse tests in a heat box, meeting GB38031, UL, and CE energy storage safety standards, and the battery factory does not need to conduct additional high-cost safety standards testing.

5. Ultra-long cycle + wide temperature range, enhancing product market competitiveness

80% DOD cycle ≥ 6000 times, calendar life 15 years; Working temperature range -20°C to +55°C, the capacity degradation in northern low-temperature and outdoor high-temperature scenarios is much lower than that of ordinary lithium batteries, helping the battery factory create differentiated long-life energy storage products.

6. Lightweight integration, reducing customer assembly costs

Integrated pre-installation finished products, wiring, collection, and fixation structures are all prefabricated and delivered, and the battery factory only needs simple wiring to install, reducing assembly labor time by 60%; Two supply modes of bare module / finished product can be provided, flexibly adapting to its own assembly production line.
