An 18650 battery holder with bare solder pins that mount straight onto a PCB or perfboard. Choose the 1 slot for a single 3.7V 18650 cell, or the 2 slot for two cells. Each cell in the 2 slot has its own + and - pin, so your board decides the wiring: series for 7.4V, or parallel for 3.7V and longer run time. There are no wire leads, so solder your own to the pins if you want flying leads.

What's in the box

1×
18650 battery holder, 1 slot or 2 slot

The holder only. No batteries or wire leads.

Great for

Running an ESP32 or Arduino project from one 18650 cell
A 7.4V supply for a small motor driver from two cells in series
Two cells in parallel for longer run time at 3.7V
A perfboard power bank with a charger and 5V converter
Swappable cells in a portable sensor or logger
A simple jig for checking spare cells

Wiring & getting started

  1. Solder first

    Push the pins through your board and solder underneath, or solder leads to the pins. Do this before any cell goes in.

  2. Choose your wiring (2 slot)

    The two cells are not joined inside the holder. For parallel, join the two + pins together and the two - pins together. For series, link the - pin of one cell to the + pin of the other and take power from the two pins left over.

  3. Add charging and protection

    For one cell, or two in parallel, our TP4056 USB-C charging module charges and protects the cell. Two cells in series need a 2S charger or BMS instead.

  4. Fit the cells

    Put each cell in the way round your board expects. The + and - ends are moulded in each bay, and the 2 slot is marked for both the parallel and the series layout.

  5. Power your build

    Need a steady 5V or 3.3V from one cell? Add our TPS63070 buck-boost module.

Frequently Asked Questions

Answers to the questions buyers ask most.

Do these come with wire leads?
No. They have bare solder pins for mounting on a PCB or perfboard. If you want flying leads, solder your own wires to the pins.
Which one should I choose?
The 1 slot holds one 3.7V 18650 cell and has 2 pins. The 2 slot holds two cells and has 4 pins, so choose it when you want 7.4V (series) or longer run time at 3.7V (parallel).
Can I wire the 2 slot in series or parallel?
Yes. The two cells are not joined inside the holder. Each cell has its own + and - pin, so your PCB sets the wiring. For parallel (3.7V), join the two + pins together and the two - pins together. For series (7.4V), link the - pin of one cell to the + pin of the other and take power from the two pins left over. The base is marked with the + and - ends for both layouts.
How do I charge the cells?
The holder has no charging circuit. For one cell, or two in parallel, add a TP4056 charger with protection, such as our USB-C module. Two cells in series need a 2S charger or BMS.
Are batteries included?
No. The holders are sold on their own so you can use your own 18650 cells.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
