Explore our leading collection of industrial energy storage cabinets, custom medical-grade power supplies, smart chargers, and bespoke automotive power modules engineered to meet strict international standards.
ELITE POWER is a premier subsidiary of GRACE DEVELOPERS CO., LIMITED. With strategic physical headquarters and advanced R&D divisions spanning Hong Kong, Shenzhen, and Dongguan, China, we represent a highly integrated new energy enterprise. Our core operations combine scientific research, hardware design, automated manufacturing, and global sales channels.
We focus on delivering next-generation intelligent green energy storage solutions. Our highly diversified portfolio comprises residential energy storage systems, industrial & commercial energy storage cabinets, multi-bay custom power management systems, 18650 smart battery chargers, supercapacitor jump starters, and heavy truck parking battery modules. By bridging raw cell development and advanced power management firmware, we provide OEM and ODM partners with uncompromised engineering quality.
Our facilities operate under stringent quality controls, validated by ISO 9001:2015 and ISO 14001:2015 certifications. In 2022, we solidified our international position by signing a long-term strategic partnership agreement with major US partners to aggressively develop optical storage, EV charging networks, and industrial power management solutions across North America.
As the primary power unit for millions of portable devices, medical equipment, tactical tools, and backup arrays, the 18650 cylindrical lithium-ion cell demands exact, reliable, and intelligent charging systems. High-volume procurement managers look beyond basic charging parameters; they require customized battery management systems (BMS), rugged hardware configurations, and multi-bay layouts that maintain structural integrity over hundreds of thousands of cycles.
Partnering with a dedicated OEM 18650 battery charger supplier allows global buyers to customize essential electrical parameters, such as constant current (CC) and constant voltage (CV) rates, cutoff thresholds, dynamic load distribution, and multi-protocol hardware interfaces. This alignment ensures the charger matches the internal resistance (IR) and nominal voltage characteristics of the target lithium cells, maximizing the operating lifespan of the battery packs.
We integrate hardware-level thermal probes and localized heat-sinks, ensuring cell temperatures remain under 45°C during high-amp charging phases.
Our OEM engineers design custom charging profiles to support standard Li-ion, high-capacity LiFePO4, and legacy Ni-MH/Ni-CD chemistries on demand.
Built-in protections safeguard against reverse polarity, short circuits, over-voltage, over-current, and prevent charging deteriorated cells.
The transition toward universal connectivity, high power density, and intelligent hardware drives modern charger developments. At ELITE POWER, our hardware engineering teams focus on three primary technological innovations:
By incorporating GaN transistors into our industrial multi-slot 18650 chargers, we reduce volume by 35% and minimize energy dissipation. This upgrade increases switching frequencies, keeping operational temperatures low even at maximum current outputs across all channels.
We design smart battery chargers featuring integrated MCU controllers and wireless communication modules (Bluetooth, Wi-Fi, RS485). These systems monitor battery life, track cycles, test internal resistance, and upload health data to centralized client management platforms.
Adhering to the latest universal power delivery protocols, our charging docks support high-wattage Type-C inputs. This compatibility allows deployment across remote research outposts, mobile response vehicles, and industrial settings using existing standard power bricks.
Cylindrical cells and modular charging hardware serve as critical components in modern energy structures. ELITE POWER develops system-wide solutions that connect consumer, industrial, and utility-scale technologies.
Medical devices require highly reliable power systems. We engineer medical-grade chargers and desktop power supplies that strictly comply with IEC 60601-1, providing low leakage current and high dielectric isolation.
For home environments, we produce low-voltage wall-mounted (10.24kWh) and all-in-one residential storage cabinets (5kWh) designed to work alongside solar setups and manage household loads.
Our heavy-duty 215kWh commercial energy storage systems support peak shaving, load balancing, and backup power for factories, processing plants, and critical logistics hubs.
We supply high-capacity truck LiFePO4 batteries, supercapacitor starter modules, and high-amp charging hardware to keep commercial transport fleets running reliably.
Operating dedicated production bases in Shenzhen and Dongguan gives ELITE POWER access to the world's most comprehensive electronics manufacturing ecosystem. Our automated facilities minimize manual assembly errors, decrease lead times, and lower production costs.
We place PCB components using high-speed surface-mount technology (SMT) machinery. Automated Optical Inspection (AOI) scans each circuit board, identifying component misalignment or soldering errors before the boards move to the casing assembly line.
Every 18650 charger undergoes rigorous functional tests, including high-potential (Hipot) isolation testing, ground continuity checks, and multi-hour automated burn-in cycles in heated chambers under full electrical loads.
Our direct access to major components, raw copper, plastics, and microprocessors allows us to adjust to market changes quickly. This strong supply network shields our global OEM partners from sudden material shortages.
Exporting electrical equipment internationally requires strict adherence to regional safety and environmental rules. ELITE POWER ensures our custom products comply with major global certifications:
Our engineering team manages compliance from the start of the design phase. We support and secure regulatory certifications, including:
Beyond certifications, we offer comprehensive post-sale support, custom localized instruction guides, and drop-shipped spare parts packages to ensure smooth operation across regional sales networks.
