FAQ

Q: Are the batteries included?
A: No. This listing is for the battery holder case only. 18650 cells are sold separately.

Q: What is the output voltage of the 4-slot holder?
A: The 4-slot holder connects cells in series, giving 14.8V nominal (4 × 3.7V). Ensure your circuit can handle this voltage.

Q: Do protected 18650 batteries fit?
A: Standard protected cells (up to ~67mm) usually fit. Cells longer than 68mm may not close the holder properly — measure your cell length first.
