From electrode coating to UN38.3 export packing, every LIMID battery is built in-house at our Foshan facility — cell production, pack assembly, and certified testing under one roof.
Our 67,000㎡ plant (53,000㎡ under roof) has manufactured batteries since 1996, with 1,900 employees running the full chain in-house — electrode coating, automatic stacking, capacity grading, pack assembly, and a UN38.3-certified testing lab. Tour the plant in the photos, or explore the 8 key stages below.
Coating · Stacking · Grading · Assembly — all in-house
Production starts at the coating line: slurry is applied in an even, pinhole-free layer onto electrode foil for our Grade-A nano LiPo cells — smooth surfaces, tight sealing, and firmly welded tabs from the first step.
Electrodes and separators are laminated on automated stacking lines with micron-level alignment, keeping internal resistance low and heat build-up minimal under high-rate discharge.
Every cell runs through the grading workshop, where capacity, voltage, and internal resistance are measured. Only cells within a narrow delta window are matched into the same pack for balance and long cycle life.
Each cell is scanned and assigned a unique ID at intake. Material batch, grading data, and the finished pack it joins are all linked — full traceability from foil to freight.
High-precision pneumatic spot welders connect cells with pure nickel strips, minimizing resistance and heat buildup.
Balance leads and protection boards are soldered onto AWG-standard silicone wire, then fitted with genuine AMASS XT60 / XT150 plugs for airtight, high-current connections.
Packs are wrapped in flame-retardant PVC, cushioned with silicone padding, and reinforced at the base and discharge leads — validated down to -20℃ for reliable cold-weather flight.
Every batch runs charge/discharge aging, capacity verification, and high-temperature storage. Final inspection covers voltage, IR, weight, and appearance before UN38.3-safe export packing.
Four dedicated workshops — film-making, winding assembly, formation, and packing — run inside 100,000-class cleanrooms held at 25℃ / RH≤40%, with fully automated lines and HD X-ray inspection on every batch.
Since 1996, LIMID has focused on one thing: building batteries buyers can trust. A national high-tech enterprise with in-house cell production, university-backed R&D, and certifications to match.
Founded in 1996 and producing batteries ever since — from early Ni-MH cells to today's high-rate lithium-ion packs. Nearly three decades of process know-how in every product.
First recognized as a National High-Tech Enterprise in 2010, with 132 invention patents. Named a Guangdong Manufacturing Top-500 company and "Hidden Champion" for ultra-high-rate jump-starter batteries.
Industry-university cooperation with Harbin Institute of Technology and Guangdong University of Technology, plus a joint research base with China Aerospace. A 135-member development team with two independent R&D systems.
100,000-class cleanrooms held at 25℃ / RH≤40% with automation level 3.0 and -40℃ dew-point control. Winding and stacking lines deliver over one million cells per day across two dedicated business units.
IQC, IPQC, and OQC checkpoints across the whole process. Safety testing per IEC 62133, UL 1642, and GB 31241 — crush, nail penetration, thermal shock, and altitude simulation — plus 100% OCV and X-ray inspection on finished cells.
ISO 9001:2015 certified; World Battery Industry Expo Gold Award winner; drafting unit of the e-cigarette battery national group standard; multiple product lines certified as Guangdong provincial high-tech products.
Multiple compliance qualifications across our product lines. Every shipment is backed by UN38.3 transport test reports and MSDS documentation — cooperation made safer, trust built on proof.
