Keep your 18650 cells organised and project-ready. These rugged ABS battery holders use bare solder pins that mount straight onto a PCB or perfboard — no wire leads to trim back — so they're ideal for clean, permanent DIY builds. The 1-slot brings out 2 pins for a single cell (3.7V). The 2-slot gives you 4 independent pins, so you can wire its two cells in parallel (3.7V, double the capacity) or in series (7.4V). Bare pins only — solder your own wires if you need flying leads.

What's in the box
Bare-pin holder only — no wire leads or batteries included.
Great for
Getting started
- Insert your cell
Snap an 18650 into the holder — the sprung contact takes flat-top or button-top cells.
- Mount and solder
Push the bare pins through your PCB or perfboard and solder underneath, or solder wires straight to the pins.
- Choose your wiring (2-slot)
Join the two + pins and two − pins for parallel (3.7V, 2× capacity), or link one cell's − to the other's + for series (7.4V).
- Power your build
Connect to your circuit, charger or BMS and you're ready to go.
Common questions
Do these come with wire leads?
No. These are the bare solder-pin type, designed to mount straight onto a PCB or perfboard. If you need flying leads, just solder your own wires to the pins.
How do I wire the 2-slot — series or parallel?
The 2-slot brings out 4 independent solder pins. Join the two + pins and the two − pins for parallel (3.7V with double the capacity), or link one cell's − to the other's + for series (7.4V). It's molded "PARALLEL" to show the default cell orientation, but the independent pins let you do either.
Do they hold protected (button-top) cells?
Yes. The sprung contacts take both flat-top and slightly longer protected button-top 18650 cells.
What's the difference between the 1-slot and 2-slot?
The 1-slot holds a single 18650 and brings out 2 pins. The 2-slot holds two cells with 4 independent pins, so you can wire them in parallel (3.7V) or series (7.4V). Choose your configuration at checkout.
Are batteries included?
No, the holders are sold on their own so you can use the 18650 cells you already have.
Good to know: These are the bare-pin version — no wire leads included. Every order is checked before it ships from our Te Awamutu stock.
