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.

FAQ

A 300W power station can typically run low-to-medium loads like phones, tablets, laptops, Wi-Fi routers, LED lights, camera chargers, small fans, and some small TVs. High-watt appliances such as kettles, hair dryers, space heaters, and most microwave ovens exceed 300W and won’t run.

Runtime depends on the battery capacity (328Wh) and your device wattage. A simple estimate is Runtime ≈ 328Wh ÷ device watts, then subtract some losses. For example, a 50W device may run roughly 5–6 hours, while a 100W load may run around 2–3 hours.

Many modern LED TVs use about 40–120W depending on size and brightness. With 328Wh, you might see roughly 2–6 hours depending on TV power draw and inverter losses.

Most full-size refrigerators need higher startup surge than 300W can supply. Some mini fridges may work if their surge and running watts stay within 300W rated / 600W peak, but results vary by model. For reliable fridge operation, higher-watt power stations are usually recommended.

It can run small electronics and low-watt appliances: laptop chargers, phone chargers, LED lights, modem/router, small fan, small TV, some CPAP machines, and small DC devices. Avoid anything with heating elements or large motors.

It depends on the TV’s wattage and how long you need to run it. For short use, a 300W / 328Wh unit can work well. For longer runtime, choose higher Wh capacity (e.g., 500–1000Wh).

Mini fridges vary widely. Many users choose 500W+ rated output and 500Wh+ capacity for more reliable results, especially for compressor startup surge. A 300W unit may work only for select low-surge models.

Yes, in most cases, because many TVs draw under 300W. Just confirm your TV’s rated watts and ensure you’re not exceeding the inverter rating when other devices are connected.

A solar panel alone usually can’t run a compressor fridge directly because output fluctuates. The common setup is solar panel → MPPT/controller → battery/power station → fridge so the battery buffers power.

Many laptops average 30–90W depending on workload and charging behavior. A 328Wh unit can often run a laptop for 3–8+ hours if you use USB-C PD efficiently and avoid heavy gaming loads.

If you need clean, quiet backup power for electronics, travel, camping, or outages, it’s often worth it. Compared to a fuel generator, a power station is silent, indoor-friendly (with ventilation), and easier to store—though it has limited runtime and output.

Common disadvantages include limited runtime (depends on Wh), limited output (watts), higher upfront cost than small power banks, and slower recharge if you don’t have high-power charging. They also can’t run high-heat appliances well at small sizes.

A generator typically burns fuel to produce power continuously while fuel lasts. A power station stores electricity in a battery and is silent and low-maintenance, but limited by battery capacity and recharge speed.

Grid electricity is often cheaper per kWh than running a fuel generator, but it depends on fuel prices and generator efficiency. People usually choose generators for long outages and power stations for convenience, noise reduction, and indoor-safe electronics backup.

Some power stations support safe “UPS/backup” style operation, but long-term best practice depends on the charger design and battery management settings. If you plan to keep it plugged in for emergency readiness, use the manufacturer-recommended mode/settings and keep it in a cool, ventilated location.
