51.2V 100Ah LiFePO4 Battery

For buyers sourcing the China 51.2V 100Ah LiFePO4 Battery, HSS Energy supplier supports bulk orders, OEM programs and configuration review before quotation. As a China LiFePO4 battery manufacturer and residential battery storage supplier, we check more than capacity alone. The catalog lists 2.56kW rated DC power and 4.1kW maximum DC power, so load selection must also consider continuous demand, starting current, equipment communication and parallel-system design.

Rack-mounted version - labels and interface configuration are confirmed per order.

Wall-mounted version - mounting accessories are confirmed per order.

Technical Specifications - 51.2V 100Ah Model

1. Capacity and Usable Energy

This 5kWh LiFePO4 battery provides 5.12kWh nominal energy and 4.61kWh usable energy at the catalog's 90% recommended depth of discharge. It is suitable for single-home storage, moving daytime solar energy into evening use and supporting selected backup loads. Actual runtime depends on load power, temperature, discharge rate and conversion losses.

2. Wall-Mounted or Rack-Mounted Format

The same 51.2V 100Ah LiFePO4 Battery can be ordered in a rack-mounted or wall-mounted enclosure. A Wall Mounted Home Battery suits projects where the wall structure, loading and service clearance have been checked, while the rack version fits battery cabinets, iron frames or equipment rooms. Brackets, terminal direction, enclosure dimensions and labels are confirmed separately.

3. Rack Deployment and Parallel Expansion

For Rack-mounted energy storage projects, the modular format allows a buyer to begin with one unit and expand after the complete system design is approved. The catalog states up to 15 units in parallel. Busbars, protection, cables, addresses, communication and equipment limits must still be checked instead of multiplying battery quantities alone.

4. BMS, Ports and Equipment Matching

Each 51.2V 100Ah lithium battery includes an intelligent BMS and CAN, RS485 and RS232 interfaces. A matching connector name does not guarantee protocol compatibility. Before production, provide the equipment brand, model, required protocol and pin definition so HSS Energy can review the communication and wiring arrangement.

Internal structure rendering - cell assembly, supports, busbars and control area.

5. Capacity Is Not the Same as Power

When evaluating 5kWh battery storage, separate energy from power. This model stores 5.12kWh, but its catalog rating is 2.56kW DC with a 4.1kW maximum. It should not be described as a battery that continuously supplies 5kW. Match the product against continuous loads, starting peaks and the equipment's power limits.

6. Solar and Backup Applications

As a 5kWh solar battery, the unit can support residential solar self-consumption, evening energy shifting, off-grid cabins, farms, small offices and suitable telecom, network or security backup loads. Air conditioners, pumps, motors and electric heating loads require a separate starting-current and simultaneous-power check.

7. Production, Compliance and Delivery Evidence

A low voltage home battery needs consistent cells, BMS protection, reliable connections, aging checks and compliant transport preparation. HSS Energy operates several production bases in China with a combined area of about 12,000 square metres and uses laser welding, automated assembly and aging-test equipment for batch and OEM projects. CE EMC, UN38.3 and RoHS files are included with this review draft, together with real packaging and batch-preparation photographs.

Supporting Certificates and Test Documents

CE EMC certificate

UN38.3 test report

RoHS certificate

Packaging and Batch Delivery Evidence

Cartons, lithium battery labels and pallet preparation

Batch packaging before shipment

Export packaging is confirmed against the transport route, destination, pallet requirements and customer labeling. The photographs show current packaging and batch-preparation capability; carton size, dangerous-goods labels, documents, pallet method and unloading arrangements follow the final shipment plan.

Frequently Asked Questions

1. Do the rack-mounted and wall-mounted versions have identical specifications?

Both versions may use the same 51.2V 100Ah electrical platform, but enclosure dimensions, weight, brackets, terminal direction and mounting accessories can differ. The final drawing and order specification take precedence.

2. How many units can operate in parallel?

The catalog lists up to 15 units. The actual quantity must be checked with the equipment, communication, busbar protection, cables and site design.

3. Can this battery continuously supply 5kW?

No. The 5.12kWh figure is stored energy. Catalog DC power is 2.56kW rated and 4.1kW maximum, so load selection must follow the power figures.

4. How is equipment compatibility confirmed?

Provide the equipment brand, model, communication protocol and pin definition. Identical port names do not guarantee that the protocol is compatible.

5. Which certification and warranty documents are available?

CE EMC, UN38.3 and RoHS files are included, while the catalog also lists MSDS. The catalog states 5+5 years; scope, start date and extension terms are confirmed in the contract.
