A: This charger is designed for 36V lithium-ion (Li-ion) and lithium polymer (LiPo) battery packs configured as 10-series cells. The output is 42V DC at 2A, which is the correct full-charge voltage for a standard 10S Li-ion pack.
Q: Can I use this charger in different countries?
A: Yes! The charger accepts universal AC input from 100V to 240V at 50/60Hz, covering virtually every country's mains standard. Simply select the correct plug type (EU, US, AU, or UK) for your region when ordering.
Q: How do I know when my battery is fully charged?
A: The built-in LED indicator tells you at a glance — a Red light means the battery is actively charging, and it switches to a Green light once the battery is fully charged and the charger has automatically stopped the charge cycle.
Q: What safety protections does this charger include?
A: The charger features four layers of built-in electronic protection: OVP (overvoltage protection), OCP (overcurrent protection), OLP (overload protection), and SCP (short-circuit protection). It is also CE and RoHS certified, confirming it meets recognised safety and environmental standards.
