【Frequently Asked Questions (FAQ)】
Q1: What makes the 4680 battery different from 18650 or 21700?
A1: The 4680 is a much larger cylindrical cell (46mm x 80mm). Its increased size allows for a single cell capacity of 24Ah, drastically reducing the total cell count needed to build large battery packs, while also improving heat dissipation and simplifying the Battery Management System (BMS).
Q2: Is this battery ready to use out of the box?
A2: Yes and No. The cell is a bare Flat Top terminal. For use in a flashlight or a direct connection, you may need to solder wires or use a spot welder to attach nickel strips. We recommend using a professional spot welder when assembling complex packs.
Q3: Can I use this 4680 battery for my electric car?
A3: This is a 3.7V single cell. To power an EV, you will need hundreds of these cells connected in series and parallel (usually between 96V and 400V configurations). Please ensure you use a high-quality BMS to manage the pack safely.
Q4: What charger should I use for this single cell?
A4: Because this is a 3.7V Lithium-Ion cell, you must use a dedicated single-slot Li-ion charger that stops charging at 4.2V. Using a charger meant for 3.2V LiFePO4 (which cuts off at 3.65V) will result in a severely undercharged cell.
Q5: Can I connect these in series or parallel?
A5: Yes. You can wire them in series to increase voltage (e.g., 4S for 14.8V) or in parallel to increase total capacity (e.g., 2P for 48Ah). Always use a certified BMS board and ensure all cells are perfectly balanced before assembly.
