Engineered with high C-rate discharge capability, multi-tier protection circuits, and precise capacitive energy transfer active balancing.
Serbia has positioned itself as the preeminent manufacturing powerhouse of the Western Balkans. As major global automotive suppliers, agricultural machinery producers, and industrial equipment manufacturers establish operations in key hubs like Belgrade, Novi Sad, Niš, Kragujevac, and Subotica, the demand for high-reliability energy systems has shifted dramatically. Standard off-the-shelf lead-acid and uncalibrated battery packs no longer satisfy the stringent requirements of modern automated systems. Custom 72V lithium power units have emerged as the definitive benchmark for high-duty operational cycles.
Information Gain Insight: Operating a 72V system architecture—specifically configured as 22S/24S LiFePO4 (Lithium Iron Phosphate) or 20S Li-ion (NMC)—provides the optimal thermodynamic and electrical efficiency equilibrium for medium-to-heavy industrial equipment. Compared to lower-voltage 48V architectures, a 72V system reduces current draw (Amperage) by 33% for equivalent power output (Watts). This directly mitigates I²R resistive copper losses, slashes thermal dissipation, enables thinner wiring harnesses, and increases overall powertrain efficiency by up to 14%.
Aligning with the EU Green Deal targets and preparing for full Carbon Border Adjustment Mechanism (CBAM) compliance, Serbian OEMs are upgrading electric mobility fleets, automated guided vehicles (AGVs), underground mining shuttle platforms in Bor, and precision agricultural autonomous spraying units across Vojvodina. Choosing a top-tier custom 72V lithium power unit factory guarantees that your equipment meets rigorous UN38.3 transport standards, CE certification, and ISO 13485/ISO 9001 quality frameworks necessary for duty-free export into the European single market.
Serbian continental weather demands ruggedized power systems. Our custom packs utilize integrated PTC heating films and active cooling channels to maintain peak discharge rates during freeze sub-zero winter temperatures and extreme summer thermal peaks.
Unlike legacy passive balancing BMS boards that burn excess voltage off as waste heat, our dynamic capacitive active balance equalizers transfer energy seamlessly between high-energy and low-energy cells, extending operational cycle life by over 30%.
Full real-time telemetry output via CAN open, RS485, and Modbus protocols. Enables Serbian fleet managers to track State of Charge (SOC), State of Health (SOH), individual cell voltages, and GPS location via custom cloud dashboards.
Every region in Serbia presents distinct environmental conditions and mechanical stresses. Our custom-engineered 72V lithium power modules are tailored to meet localized technical standards and heavy operational demands.
Modern distribution centers along the Belgrade-Novi Sad logistics corridor operate continuous 24/7 automated material handling systems. Our 72V LiFePO4 power units support 1C fast opportunity charging during short breaks, eliminating battery swap downtime. Integrated active BMS balance circuits ensure cell voltage harmony even under rapid charge-discharge cycling.
Underground mining operations require zero-emission equipment capable of enduring extreme mechanical shock, high humidity, and heavy dust. We design custom 72V packs encased in IP67-rated welded 316 stainless steel enclosures with internal shock-absorbing elastomer grids and explosion-proof flame arrestor vents.
The fertile agricultural plains of Vojvodina demand lightweight yet energy-dense energy storage systems. Our high-energy NMC 72V battery systems power autonomous electric spraying robotics and light tractors, delivering high torque across muddy soil while minimizing ground compaction.
Municipal street sweepers, electric garbage compactors, and last-mile urban transport platforms require dependable daily range and maintenance-free longevity. Our 72V custom power modules provide 3,500+ charge cycles, reducing total cost of ownership (TCO) by over 55% compared to legacy lead-acid systems.
As a world-leading custom lithium-ion battery pack manufacturer, APEX Mobile Power provides full end-to-end engineering, testing, and production services. We work directly with Serbian OEM design engineers from initial concept prototyping through to serial mass production.

Direct technical answers to common questions raised by Serbian equipment manufacturers, systems integrators, and industrial buyers.
All APEX custom 72V power units are manufactured in compliance with international battery standards including UN38.3 (Transport Safety), CE, IEC 62133, RoHS, and REACH. We provide complete certification dossiers and UN38.3 test summary reports required by Serbian Customs (Uprava Carina) and EU border freight forwarders, ensuring fast clearance via Danube river ports or direct road transport corridors.
72V provides the ultimate balance between electrical safety and power efficiency. Under European safety directives (such as EN 60664), voltages below 120V DC remain classified within Safety Extra Low Voltage (SELV) limits, significantly simplifying safety insulation design and technician certification requirements. Meanwhile, 72V delivers 50% more power than 48V at identical current rates, minimizing motor heat and wire gauge weight.
Yes. Our in-house firmware engineering team customizes CANbus (CAN 2.0B, CANopen, J1939) and RS485 communication protocols to match your vehicle control unit (VCU), motor drive inverter (e.g., Curtis, Sevcon, Danaher), or charger protocol. We provide complete DBC files and register maps during the OEM integration phase.
Standard lithium batteries suffer severe capacity drop and cannot be safely charged below 0°C without causing lithium plating. APEX addresses this by integrating automatic internal PTC heating pads managed directly by the Smart BMS. When connected to a charger in cold weather, the BMS directs energy to warm the cells to +5°C before initiating charge current, guaranteeing 100% capacity retention and zero thermal degradation.
For custom 72V power pack designs, initial 3D enclosure modeling, thermal simulation, and schematic drafting take 1 to 2 weeks. Custom sample prototypes are produced and drop-shipped to Serbia within 3 to 4 weeks. Upon prototype validation, serial mass production requires 4 to 6 weeks, backed by flexible scheduled release orders to support your assembly line schedules.
We offer both high-durability LiFePO4 (LFP) cells for heavy industrial equipment, AGVs, and stationary energy storage where maximum cycle life (3,500–6,000 cycles) is required, and energy-dense NMC (Nickel Manganese Cobalt) cells for lightweight e-mobility, agricultural drones, and high-power density applications where minimum weight is critical.
Accelerate your equipment electrification project with custom engineering support, active balancing BMS technology, and certified battery manufacturing tailored for Serbia and the European market.
