OEM&ODM Process

Phase 1

Confirm Requirements and Finalise the Solution

We collect all customer specifications: voltage, capacity, dimensions, communication protocol, etc. Then we decide if it is a pure OEM job (build exactly to your drawings) or an ODM job (we provide the design). We issue a clear BOM (bill of materials) and 2D/3D drawings for both parties to sign off, avoiding any later misunderstandings.

Phase 1
Phase 2
Phase 2

Procurement and Incoming Inspection

We purchase all materials according to the BOM: cells, enclosure, brackets, screws, wiring, BMS boards, etc. When goods arrive, we do sampling or 100% inspection. For cells, we measure voltage, internal resistance and check appearance. For structural parts, we check dimensions and hole sizes. Any non‑conforming items are rejected and never go into our warehouse.

Phase 3

Cell Sorting and Matching

We group cells from the same batch by voltage and internal resistance values. We then match cells with the closest parameters into one set (for example, if a string uses 4 cells, the voltage and resistance differences among those 4 must stay within our set limits). This directly affects how long the battery pack will last without performance decay.

Phase 3
Phase 4
Phase 4

Laser Welding and Module Assembly

We fix cells into holders, then laser‑weld the tabs (connectors). We do pull‑force tests on sample weld spots to check strength. After that, we fasten the welded sub‑modules into the enclosure or tray, using torque‑controlled tools to apply the correct tightening force.

Phase 5

BMS Installation and Wiring Connection

We mount the main BMS and slave boards in their designated positions, then plug in all voltage sampling wires and temperature sensors. We always have a two‑person verification of the wiring sequence – this prevents reverse connections that could burn the boards when we power up.

Phase 5
Phase 6
Phase 6

First High‑Voltage Safety Test

We apply high voltage between the positive/negative terminals and the enclosure to measure insulation resistance and withstand voltage. We check for any leakage or breakdown. If this test fails, the module goes back for rework immediately – it does not move forward.

Phase 7

High‑Temperature Standing and Self‑Discharge (K‑Value) Check

We place the modules in a 45 °C room for 24–48 hours. We measure voltage before and after the standing period, then calculate the daily voltage drop (K‑value). Units with excessive drop are rejected because they indicate internal micro‑shorts that could cause early failure later.

Phase 7
Phase 8
Phase 8

Charge/Discharge Aging and Capacity Calibration

We connect the modules to charge/discharge equipment and run several full cycles at the current specified by the customer. During the process, we record actual discharge capacity, charge/discharge efficiency, and the temperature/voltage differences among individual cells. If all data stay within our acceptance limits, we calibrate the final rated capacity. If not, we isolate and analyse the failed units.

Phase 9

Final Inspection, Labelling and Packaging

We re‑measure total voltage, internal resistance and insulation performance. We check appearance for scratches, gaps, or damaged screws. We attach a permanent nameplate (with serial number), UN38.3 hazardous‑goods label, and all required operation warning labels. Then we package the battery with foam or cardboard for shock protection, as per customer requirements, and record the final weight.

Phase 9
Phase 10
Phase 10

Shipment and Document Handover

We verify the shipping quantity, address and consignee. We prepare all accompanying documents: factory test report, MSDS, UN38.3 test summary, and transport condition certificate. We arrange pickup with our logistics partner, and after dispatch we send the tracking number and estimated arrival time to the customer.

Frequently Asked Questions (FAQ)

The battery stores 16.07kWh total energy. With LiFePO₄ chemistry and built‑in BMS protection, you can safely use over 90% (≈14.5kWh) per cycle without damaging battery life.

Yes. The inverter delivers 6000W continuous and 12,000VA peak (surge) for up to 10 seconds. This can start most 2‑3HP air conditioners, refrigerators, compressors, and submersible pumps.

Yes. The AC input accepts 90‑280Vac from the grid or a generator. You can use it as a battery backup system (UPS‑like) and charge purely from AC power.

Typical transfer time is <10ms (milliseconds). This is fast enough to keep computers, routers, and sensitive electronics running without interruption.

  • Max PV open circuit voltage: 500Vdc

  • MPPT operating range: 120‑450Vdc

  • Min activation voltage: only 80V

  • Max MPPT power: 9000W

  • Max charging current: 120A

You can connect most standard monocrystalline/polycrystalline panels in series. Example: 12× 450W panels (5400W) works well.

Yes. Multiple identical units can be paralleled via CAN/RS485 communication to increase total energy and power output. Contact us for parallel configuration details and required accessories.

Built‑in WiFi allows connection to a free mobile APP (iOS/Android). You can view real‑time battery SOC, PV input, AC output, history, and receive fault alerts. Local monitoring is also available via LCD touch screen.

  • Cycle life: ≥6000 cycles at 25°C, 0.5C, 70% SOH (end of life)

  • Standard warranty: 5 years (extendable)
    The battery is based on Grade A LiFePO₄ cells (BYD cell platform). Under normal daily cycling, 6000 cycles equals about 16 years of service.

The BMS and inverter support CAN, RS485, USB, and WiFi. These allow integration with home energy management systems, generators, or third‑party monitoring platforms.

Absolutely. AC input accepts 90‑280Vac, 50/60Hz. You can set the charging current from 2A to 120A via LCD or APP to match your generator’s rated power. The system can automatically start the generator (with external ATS or generator auto‑start signal).

  • Dimensions: 580×580×643 mm

  • Weight: ≤138.5 kg

  • IP20 rating – indoor use only (garage, utility room, basement)

  • Ambient temperature: -10°C to +60°C

  • Max altitude: 4000m (derating above 1000m)

We recommend professional installation by a certified electrician. Wall mounting optional, floor standing recommended.

Yes. We are an OEM/ODM factory. Customization options include: enclosure logo, LCD boot screen, packaging, user manual, and even white‑label mobile app. MOQ starts at 50 units. Sample orders available.
