It handles 1–6 cells for lithium-based packs, 1–15 cells for NiCd\/NiMH, and 2–20V for Pb batteries — making it one of the most versatile RC battery chargers available.\u003c\/p\u003e\n\u003ch4\u003eQ: Does the HTRC B6 require a separate power supply?\u003c\/h4\u003e\n\u003cp\u003eA: No. The B6 AC model includes a built-in AC input that accepts 100–240V AC (50\/60Hz), so it works worldwide right out of the box. A 15V 6A adapter is included in the package. It can also be powered from a 12V DC car battery (DC 11.0–18.0V) for field use.\u003c\/p\u003e\n\u003ch4\u003eQ: What does the \"balance\" function do on the HTRC B6 charger?\u003c\/h4\u003e\n\u003cp\u003eA: The balance function monitors and equalizes the voltage of each individual cell within a lithium battery pack (LiIon, LiPo, LiFe). This ensures all cells reach the same voltage level, which extends pack lifespan, maintains consistent performance, and improves safety during charging cycles.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I set up the HTRC B6 charger correctly?\u003c\/h4\u003e\n\u003cp\u003eA: Always connect the AC adapter to the wall outlet first, then connect the charger to your battery pack.
