Pknergy pitches custom 18650 battery packs at Hong Kong Electronics Fair

Pknergy used the 2026 Hong Kong Electronics Fair in Hong Kong to promote custom 18650 battery packs for medical devices, AGVs and other OEM products. The company highlighted high cycle life, BMS integration and rapid prototyping as demand for industrial and portable power stays strong.

Why it matters: - 18650 battery packs remain a core option for OEM products in 2026, especially in portable devices and industrial equipment. - Pknergy is positioning custom packs as a way to solve power-density, safety and integration challenges for medical devices, robotics, AGVs and light electric vehicles. - The push comes as manufacturers seek batteries that can support longer life, tighter size constraints and real-time power monitoring.

What happened: - Pknergy showcased its 18650 battery pack lineup at the HKTDC Hong Kong Electronics Fair 2026 in Hong Kong. - The company highlighted custom packs built for industrial and medical applications. - Pknergy said it serves more than 5,000 global clients. - Pknergy said its packs deliver 99.9% consistency in internal resistance. - The company directed readers to more information.

The details: - Pknergy said its 18650 packs use cells from EVE and CATL, including INR and LFP series. - The company said its packs reach energy densities of up to 250 Wh/kg. - Pknergy said discharge rates can reach 10C. - The company said it supports pack configurations from 1S1P to 20S10P. - Pknergy said it offers 72-hour rapid prototyping to verify technical feasibility before mass production. - The company said its cell grading process keeps internal resistance nearly identical across 3.7V ICR18650 units in a pack. - Pknergy said proprietary BMS units protect against overcharge, over-discharge and short-circuiting. - The company said its industrial BMS options support CANBus and RS485 communication. - Pknergy said the BMS can provide real-time State of Charge and State of Health data. - The company said its lithium iron phosphate and lithium polymer packs can exceed 500 to 2,000 cycles depending on chemistry. - Pknergy said its latest 18650 solutions can retain 80% State of Health after 2,000 cycles at 100% Depth of Discharge. - The company said its packs are designed to reduce vibration and thermal stress. - Pknergy said the products are deployed in more than 150 countries. - The company was established in 1998 and said it has 28 years of engineering experience in energy.

Between the lines: - The 18650 format is still commercially relevant even as larger cells like 21700 and 4680 dominate parts of the electric vehicle market. - Pknergy is framing itself less as a component supplier and more as a development partner that can help OEMs turn power specs into mass production. - The emphasis on BMS communication, cycle life and rapid prototyping signals that buyers want batteries that plug into smarter, more demanding products. - The fair setting also suggests Pknergy is targeting global distributors and engineers looking for supply-chain transparency and safety assurances.

What's next: - Pknergy is seeking OEM and ODM partnerships beyond one-off sales. - The company says future work will focus on higher energy density, improved safety and better thermal runaway resistance. - Pknergy also said it wants to support global carbon-reduction goals through more efficient energy storage. - The company is likely to use the Hong Kong fair as a lead-generation event for 2026 and 2027 product cycles.

The bottom line: - For custom OEM products, the 18650 battery pack is still a practical, scalable format in 2026, and Pknergy is betting that engineering support and tight manufacturing control will keep it in demand.
