Two battery-electric product lines on one shared 64V LiFePO₄ battery standard. Concrete Series where you have grid power — a battery built to survive years of daily fast-charging. PowerCore System for complete off-grid jobsites — including AC and welding — where you don't.
Most "electric" construction equipment is half-electric — battery tools that run out before the work is done, or battery tools that still need a generator on site for AC power. We built two distinct products around what actually breaks on real jobsites: a battery that lasts for years where grid is available, and complete off-grid power where it isn't.
For concrete crews where the jobsite has grid power. The active-cooled fast charger refills packs all day without the heat that wears batteries down — so the fleet still hits full power years in. Two packs hot-swap to keep the tool running.
Compete against: Milwaukee MX FUEL · Bartell · Wacker Neuson battery tools — on battery life, not on price.
See Concrete Series →For crews where the grid isn't available and a generator isn't allowed. Pack + Station + Dock = full 5.5 kW AC, 150A welding, and every tool on one battery system. No generator on site.
Compete against: portable diesel/gas generator + mixed gas tool fleet — on the only-complete-solution argument.
See PowerCore System →Battery-electric concrete tools that work like gas tools — and a battery built to survive years of daily fast-charging. The active-cooled fast charger pulls out the heat that normally kills cycle life, so packs recharge shift after shift and still deliver full power years in. Two packs hot-swap to keep your crew running on jobsite grid power.
Tell us your application — we'll arrange a demo or pilot of the Concrete Series as samples become available (Q3 2026).
When you can't run grid power and you can't run a generator, you need a complete battery-electric jobsite — power tools and AC power on one system. PowerCore replaces the portable generator and every gas tool, in one integrated battery platform.
Tell us your off-grid use case — we'll discuss specifications, pilot terms, and timeline as we approach NA launch (Q3 2026).
TSEMODUX is the North American equipment brand of CQTS — Chongqing Tuosi Power Technology Co., Ltd., a manufacturer specializing in battery power systems and battery-electric equipment. We design a single shared 64V LiFePO₄ battery standard, with two product lines built around the two distinct ways crews actually fail to be productive: battery runtime on the jobsite, and complete jobsite power without a generator.
We are currently preparing our North American market launch — finalizing production samples and entering safety certification — and we welcome early conversations with rental fleets, contractors, municipal procurement teams, and industry partners.
Founder: Chenglin Jiang
All TSEMODUX products are currently in the prototype and pre-production stage. North American safety certification — to applicable UL/CSA standards, with FCC/IC and DOE/NRCan compliance — is being pursued through SGS North America, an OSHA-recognized Nationally Recognized Testing Laboratory (NRTL). Certification is expected in September 2026.
Production samples are finalizing in Q2–Q3 2026, after which we'll be scheduling demos and pilots with interested partners. Pre-launch conversations on specifications, commercial terms, and pilot scope are welcomed now.
