Explore our core production lineup of high-current battery management assemblies, capacitive active balancers, and intelligent protection circuits tailored for high-discharge industrial power tools and energy systems in Romania.
An in-depth analysis of battery chemistry, C-rate dynamics, thermal mitigation, and structural packaging required for heavy-duty industrial tools in demanding European environments.
Professional-grade cordless tools—such as SDS-Max rotary hammers, 230mm angle grinders, and high-torque impact wrenches—demand instant peak currents exceeding 30C discharge pulses. Traditional energy-dense cells exhibit high internal DC resistance (DCR), leading to excessive voltage sag and thermal shutdown under load.
At our manufacturing facility, we prioritize ultra-low impedance cylindrical cells (18650 and 21700 form factors) utilizing advanced Nickel-Manganese-Cobalt (NMC 811/532) and Tabless cell architectures. By utilizing multi-tab designs, internal resistance is reduced by up to 60%, allowing sustained 15C continuous discharge without overheating.
A power tool battery pack is only as reliable as its protection logic. High peak currents create dynamic voltage unbalance across series-connected cell strings. Conventional passive balancing bleeds energy as heat—adding unwanted thermal stress to the pack enclosure.
Our OEM packs feature capacitive energy-transfer active balancing (1.5A–5.5A). Energy is dynamically shuttled from higher-voltage cells to lower-voltage cells during both charge and high-rate discharge cycles, maximizing usable capacity by 18% and extending cycle life beyond 1,200 full charge/discharge cycles under severe duty.
Heavy impact and drop forces (MIL-STD-810G compliant) are common on Romanian construction sites. Our battery packs incorporate over-molded thermoplastic elastomers (TPE), flame-retardant polycarbonate enclosures (UL94-V0), pure copper nickel-clad interconnect busbars, and silicone-encapsulated PCB assemblies to ensure complete isolation against vibration, dust, and moisture ingress (IP65 standard).
Romania's rapidly growing industrial sector requires robust, high-discharge power tool solutions tailored to specific regional operational demands and extreme environmental conditions.
Commercial real estate development and major civil engineering projects in Bucharest mandate heavy-duty 18V and 36V cordless demolition hammer drills and concrete cutters. Our battery packs deliver sustained 20A continuous power to prevent stall conditions on reinforced concrete.
Assembly lines in Dacia (Mioveni) and Ford Otosan (Craiova) rely heavily on precise cordless torque wrenches and automated assembly tools. Our high-rate packs provide consistent terminal voltage curves to ensure exact torque control across 8-hour production shifts.
Maritime repair yards along the Danube and Black Sea coast subject tools to intense humidity, salt mist, and continuous high-load grinding. Our IP65-sealed conformal-coated battery packs protect internal electronics against corrosion and short circuits.
High-capacity 40V Max and 80V battery packs engineered for cordless chainsaws, brush cutters, and forestry equipment operating in the Carpathian Mountains (Cluj, Sibiu, Brașov). Featuring specialized low-temperature electrolyte chemistry functional down to -20°C.
Western Romania’s logistical centers rely on automated guided vehicles (AGVs) and heavy-duty cordless strapping tools. Our active-balancing LiFePO4 and NMC modules guarantee zero-maintenance multi-shift operational readiness.

Navigating the evolving regulatory landscape and technology shifts reshaping the European power tool industry.
As an EU member state, Romania strictly enforces the new EU Battery Regulation framework. Importers and OEM tool manufacturers must adhere to mandatory carbon footprint declarations, supply chain due diligence, and QR-code accessible Digital Battery Passports by 2027.
Our factory provides end-to-end trace-ability, recycled material documentation (Cobalt, Lithium, Nickel content tracking), and full compliance with CE, RoHS, REACH, and UN38.3 transport safety certifications—ensuring smooth clearance at Port of Constanța or border customs.
Romanian construction contractors are rapidly phasing out heavy 230V corded generators on remote sites in favor of high-torque brushless cordless systems. This transition requires multi-voltage power tool battery platforms (e.g., 18V/36V auto-switching or dual 20V Max systems).
We provide complete OEM tooling development for multi-voltage communication interfaces, enabling single battery packs to powershift between low-current long-runtime tools and extreme-discharge heavy demolition equipment.
Addressing critical technical, regulatory, logistical, and commercial inquiries for importing OEM power tool battery solutions to Romania.
We provide complete EU compliance documentation packages with every batch shipment, including CE Declarations of Conformity, RoHS 2.0 chemical analysis, REACH disclosures, UN38.3 transport testing reports (with summary MSDS), and IEC 62133 safety certification. All packages are labeled according to dangerous goods transport regulations (Class 9 UN3480/UN3481).
Yes. Our factory provides full turnkey ODM services. We specialize in custom plastic injection tooling design, mechanical latch mechanism engineering, terminal connector pin customization, and private-label branding (laser engraving, mold texturing, and silk-screen color matching) to integrate with your existing cordless tool line.
Our sub-zero winter battery packs utilize specialized low-impedance electrolyte formulations and integrated NTC-managed thermal heating elements within the BMS. This prevents lithium plating during sub-zero charging and allows full rate discharge down to -20°C without premature low-voltage cutoffs.
For custom OEM battery pack development, prototype samples are delivered within 15–25 business days following 3D design freeze. Mass production MOQ starts at 500 units per model. Delivery via sea freight to Port of Constanța takes approximately 28–35 days, or 10–14 days via direct air freight to Bucharest Henri Coandă Airport (OTP).
Our proprietary Smart BMS incorporates ultra-low Rds(on) power MOSFETs mounted on heavy copper-core substrate heat sinks. Combined with algorithmic dynamic current-limiting firmware and active capacitive cell balancing, heat buildup inside the pack is reduced by up to 40%, enabling continuous high-amp output without triggering thermal protection shutdowns.
We offer full customization for smart tool-to-battery communication protocols, including UART, RS485, CANbus 2.0B, and Bluetooth 5.0 mobile telemetry interface. This allows real-time state of charge (SoC), state of health (SoH), temperature, and cycle count data to be transmitted directly to the tool or fleet management software.
A vertically integrated global battery manufacturer delivering technical authority, rigorous quality management, and end-to-end OEM execution.
Our production facilities hold dual ISO 9001:2015 quality management certification and ISO 13485:2016 medical-grade assembly accreditation, audited independently by SGS. Every battery pack undergoes 100% automated optical inspection (AOI) and computer-controlled end-of-line (EOL) testing.
With 60+ full-time battery engineers and 8% of annual revenue reinvested in R&D, we handle chemical selection, thermal simulation, firmware coding, PCB layout, and mechanical structural testing under one roof.
We provide complete freight management services including DDP (Delivered Duty Paid) shipping to major Romanian industrial centers including Bucharest, Cluj-Napoca, Timișoara, Brașov, and Iași—handling all customs declarations and tax clearance seamlessly.
