Q&A:

Q: What are the key specifications of the Henryuan 54.6V 4A charger?
A: Henryuan 54.6V 4A charger is specifically designed for 13S (48V) Lithium-ion battery packs. It features a precise CC-CV-Trickle Current charging logic to ensure maximum battery life and safety. With a high output of 4A, it offers fast and efficient charging while maintaining global safety standards (UL, cUL, ETL, UKCA, CCC, PSE, CE, FCC, SAA, KC).

Q: Is this 54.6V charger compatible with 48V E-bike batteries?
A: Yes. A 48V lithium-ion battery pack typically consists of 13 cells in series (13S). The maximum fully charged voltage for these packs is 54.6V. Therefore, the Henryuan 54.6V 4A charger is the ideal professional-grade solution for 48V e-bikes, electric scooters, and other mobility devices using 13S Li-ion technology.

Q: What safety certifications does the Henryuan 13S battery charger hold?
A: Henryuan prioritizes safety for global markets. This charger is fully certified under:
UL & ETL for North America, CE & GS for Europe, UKCA for the United Kingdom, SAA for Australia, PSE for Japan and KC for South Korea. These certifications ensure the charger meets rigorous fire safety and electromagnetic compatibility standards.

Q: How does the 3-stage charging logic benefit the battery?
A: Unlike basic power adapters, Henryuan chargers use a sophisticated 3-stage charging process:
Constant Current (CC): Rapidly charges the battery to about 80% capacity.
Constant Voltage (CV): Slowly tops off the battery to 100% while reducing current to prevent overheating.
Trickle Current: maintains a tiny maintenance charge to ensure the battery is perfectly balanced and safe to use.

Q: Can I customize the output connector for my specific device?
A: Absolutely. Henryuan offers extensive OEM/ODM customization. While the standard model might feature common plugs, we can provide specialized connectors including DC 5.5*2.1mm, XLR (3-pin), XT60, XT90, Anderson connectors, or aviation plugs to match your specific application, whether it's for robotics, AGVs, or electric vehicles.
