About us
A decade of energy storage manufacturing excellence.
Residential Solar Energy Storage Battery Solution Manufacturer
TURSAN is a high-tech enterprise integrating R&D, manufacturing, and global sales of lithium battery–based energy storage systems. Founded in 2016, we operate a 20,000+m² production facility producing reliable LiFePO4 power solutions for residential, commercial, and outdoor applications.
Through a strategic partnership with BYD, we co-manufacture larger-capacity, safer, and more environmentally friendly portable power stations and home battery backups. Today we serve global brand owners, distributors, EPC contractors, and project developers in over 60 countries — saving OEM clients up to 20% in annual sourcing cost while meeting the toughest international safety standards.
OEM&ODM Process
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
