A Greer company that specializes in laser welding technology is throwing open its doors next week for a free, two-day event where local manufacturers can watch battery welding equipment in action without ever booking an appointment. Li10, which operates out of 55B Concourse Way, is hosting the Battery Welder Open House on Nov. 17 and 18, giving engineers and production teams a rare chance to see the machinery up close.
According to the Post and Courier, visitors can show up at any time across both days without scheduling ahead, and the event itself is free. Li10 is the North American partner for RMA, a European manufacturer of laser welding systems used in battery production, according to RMA, which lists the Greer dates on its own site as Nov. 17-18, 2026, at what it calls its partner lab. Li10 describes itself on its blog as helping bridge the gap for manufacturers who need local sales, service and application support rather than relying solely on European-based resources.
What the Open House Offers Local Manufacturers
The pitch, per the Post and Courier's report, is straightforward: local manufacturers, engineers and R&D teams get a chance to test laser welding on their own parts without flying to Europe. RMA's own site backs up that general approach, describing its Laser Application Center model as one where customers bring parts and applications engineers run trials before anyone commits to buying a machine. RMA frames its Greer site specifically as its U.S. partner facility, equipped with a Battery Welder series machine on site, offering North American customers the same process-validation approach used at its primary facility in Poland.
Alongside the open house, a separate laser welding lunch and learn is scheduled for Nov. 17 from noon to 1:30 p.m., according to the Post and Courier's report, and that session requires an RSVP rather than walk-in attendance. SC Competes says it will co-host that session alongside RMA and Li10, offering lunch, networking and what it describes as an inside look at laser welding technology — covering the fundamentals of how it works as well as its applications in advanced manufacturing and battery production.
A Growing Battery Corridor Around Greer
The timing lands squarely within a stretch of real momentum for South Carolina's battery and EV manufacturing sector, which the Post and Courier's report describes simply as growing. That's visible in the scale of other projects nearby: BMW is preparing to open Plant Woodruff, which the automaker says will bring about 300 jobs to the area, according to Fox Carolina. That plant will produce sixth-generation batteries for electric vehicles built at BMW's nearby Spartanburg plant, part of a recent $1.7 billion investment by the company.
A University of South Carolina Darla Moore School of Business study found BMW now has a $36 billion economic impact on the state, up 35% from four years earlier, Fox Carolina reports. The broader trend lines tell a similar story: South Carolina's transportation equipment manufacturing sector grew from 11.9% to 20.3% of the state's overall manufacturing industry over the preceding 20 years, according to data presented in February and cited by Greenville Business Magazine. That same report estimated automotive manufacturing now contributes $64.6 billion in annual economic impact and 119,475 jobs statewide.
Greer's Battery Manufacturing History
Greer itself has already seen this kind of investment play out before. Proterra expanded in 2021 with a $76 million, 327,000-square-foot battery-building facility in the city, per Greenville Business Magazine's reporting, and Volvo purchased that same battery plant in 2024. Li10's open house adds another, smaller chapter to that pattern — not a new factory, but a service and testing hub meant to support the manufacturers building out the region's battery supply chain.
For now, the practical details remain limited to what Li10 and RMA have published themselves: a free, walk-in open house on Nov. 17 and 18, and a separate RSVP lunch session the first day. Li10 describes its broader work as partnering with manufacturers to improve precision, efficiency and performance through laser process products and services, with offerings ranging from handheld laser welding to advanced research and development support.
