High-Precision Power Solution for 7.2V / 7.4V (2S) Battery Packs
Henryuan 8.4V 1A Lithium-ion Battery Charger is a professional-grade power adapter engineered for maximum reliability and global market accessibility. Specifically designed for 2-cell (2S) lipo/li-ion battery configurations, this charger utilizes an advanced CC-CV-TC (Constant Current - Constant Voltage-Trickle Current) charging profile to ensure peak battery performance and extended cycle life.
With a full suite of international safety certifications, including UL/cUL, CE, EMC, FCC, SAA, PSE, UKCA and CCC this unit allows manufacturers to ship products globally with complete regulatory confidence.
Key Features & Benefits
Global Compliance & Safety-First Design: Fully certified under UL/cUL/FCC (North America), CE-LVD/EMC (Europe), UKCA(United Kingdom), SAA (Australia), PSE (Japan), CCC(China). It features multi-layered protection against over-voltage, over-current, short circuits, and reverse polarity.Intelligent 3-Stage Charging(8.4V 1A Li-ion Charger):
- Constant Current (CC): Fast charging at a stable 1A until the battery reaches capacity.
- Constant Voltage (CV): Precision topping-off to ensure a 100% full charge without overstressing the cells.
- Trickle Current(TC): Low-current charging protects the battery and keeps it fully charged.
Universal AC Input: Supports 100V–240V AC (50/60Hz), making it compatible with power grids anywhere in the world.
Smart LED Indicator: Provides immediate visual feedback—Solid Red during active charging and Solid Green when the battery is fully charged or disconnected.
Premium Build Quality: These 2S Lithium-ion Battery Charger constructed with high-impact, flame-retardant UL94V-0 PC material for superior heat dissipation and durability in industrial or consumer environments.

FAQ
Q1: Is this 8.4V charger compatible with my 7.2V or 7.4V battery pack?
A: Yes, absolutely. In the lithium-ion industry, 7.2V and 7.4V refer to the nominal (average) voltage of a 2S (2-cell) pack, while 8.4V is the peak (fully charged) voltage. Our charger is precision-engineered to bring these 2S packs to their maximum safe capacity of 8.4V.
Q2: Does this charger meet the safety standards for my specific country?
A: Yes. Henryuan is a global manufacturer, and this 8.4V 1A model is fully certified for international markets:
United States & Canada: UL, cUL, FCC. Europe: CE, GS, RoHS, REACH.
United Kingdom: UKCA, Japan: PSE. Australia: SAA.
This extensive certification profile ensures seamless customs clearance and guarantees regulatory compliance for your products.
Q3: Can I customize the AC plug and DC connector for my region?
A: Certainly. We offer a variety of regional AC power plugs, including US, EU, UK, and AU standards. For the output side, we provide a wide range of DC connectors (such as 5.5x2.1mm, 5.5x2.5mm, 3.5x1.35mm, or custom aviation plugs) to ensure a perfect fit for your device.
Q4: Is this charger noisy during operation?
A: No. Because this is an efficient 8.4W unit, it utilizes natural convection cooling without the need for an internal fan. This ensures a completely silent operation, making it ideal for medical environments, beauty devices, or home electronics.
