Henryuan 16.8V 1A Interchangeable Plug Li-ion Battery Charger (Model: HRY16801000) is an engineering-first power solution designed specifically for 4-Series (4S) 14.4V/14.8V nominal Lithium-ion battery packs.
By integrating a premium detachable/interchangeable AC plug mechanism (US, EU, UK, AU, JP, KR), this single charging platform eliminates international supply chain bottlenecks. Global OEMs can now package one universal power core for all destination markets, drastically slashing inventory overhead, reducing SKU complexity, and simplifying warehouse logistics. It is the ideal premium charging infrastructure for:
Portable Medical Devices and Home Healthcare Equipment.
Smart Home Automation, Robotics, and Wireless Vacuum Cleaners.
High-End LED Photographic Lighting Arrays.
Handheld Test and Measurement Instruments.
Key Engineering Advantages
🔌 One Charger, Global Access: Toolless AC Head Swapping
No separate AC power cords required. Henryuan's robust slide-and-lock mechanical interface allows field operators or end-users to swap regional AC pins in under 2 seconds without tools. The connection maintains tight, high-voltage structural integrity that easily resists micro-vibrations and long-term wall outlet wear.
⚙️ Pure Hardware-Controlled 3-Stage Charging Profile
Small-capacity lithium packs (typically 2Ah to 5Ah paired with a 1A charger) have a narrow safety tolerance window. Henryuan completely abandons cheap, failure-prone software-driven micro-controllers in favor of pure analog hardware feedback loops. The system guides cells through a surgically precise CC (Constant Current) - CV (Constant Voltage) - Floating curve. It locks bulk current at exactly 1.0A, transitions seamlessly at the 16.8V threshold, and executes a clean shutdown, extending battery lifecycle longevity by 10% to 15%.
🎯 Surgical ±0.2V Charging Accuracy
Lithium-ion chemistries possess zero tolerance for voltage overshoot. A loose-tolerance power adapter drifting to 17.0V can cause individual series cells to drift past their electrochemical limits, causing internal outgassing or forcing the battery pack's internal Battery Management System (BMS) into a permanent emergency lockout. Henryuan’s industry-leading $\pm0.05\text{V}$ cutoff precision ensures maximum pack saturation safely every single time.
🔒 The "Frozen PCBA" Sourcing Guarantee
To protect global procurement divisions from unannounced component degradation or material shifts across multi-year global supply contracts, Henryuan enforces a strict BOM-locking (Bill of Materials) framework. Once your engineering team certifies our initial 16.8V 1A sample, the internal board layout, component brands (such as high-temperature electrolytic capacitors), and circuitry parameters are 100% permanently frozen for all future mass-production batches.

Integrated Protection Suite
Short-Circuit Protection (SCP): Instant cutoff with automated hiccup-mode recovery once the fault is removed.
Over-Voltage Protection (OVP): Prevents unexpected input line spikes from transferring damage to your battery cells.
Over-Current Protection (OCP): Firmly clamps the output threshold at 1.0A to eliminate over-amperage degradation.
Reverse Polarity Protection: Protects the circuitry if the user accidentally reverses positive and negative terminal leads.
OEM/ODM Services
As a premier, vertically integrated manufacturer of both chargers and custom cable harness assemblies, Henryuan eliminates supply chain friction by offering flexible backend options to match your product interface and charging parameters perfectly:
DC Output Connectors Available: DC Barrels (5.5mm x 2.1mm / 2.5mm), XLR (3-pin), Aviation Plugs, RCA, 3-Pin Inline, Alligator Clips, or custom low-voltage wire harnesses utilizing premium LEMO & Weipu compatible lines.
FAQ
Q: Can this 16.8V 1A charger be used to charge a 12V LiFePO4 battery pack?
A: No. A 12V LiFePO4 pack consists of 4 cells in series (4S) and requires an absolute maximum charging cutoff voltage of 14.6V. This charger outputs 16.8V, which is calibrated strictly for 4S Lithium-ion (NMC) chemistries. Pushing 16.8V into a LiFePO4 pack will destroy the cells and trigger BMS protection. For LiFePO4 solutions, please request our dedicated 14.6V charging models.
Q: What do the LED diagnostic lights mean during operation?
A: The charger features clear dual-color LED metrics: Solid Red means the Constant Current or Constant Voltage bulk phase is actively running; Solid Green signals that the current has safely tapered into termination, the battery is 100% saturated, and the safety cutoff has engaged.
Q: Does Henryuan perform 100% testing on mass-production batches?
A: Yes. Under our ISO 9001:2015 quality infrastructure, 100% of finished mass-production units undergo an intensive full-load burn-in testing process for a minimum of 4 consecutive hours to eliminate any infant mortality defects before final global export packaging.
