Product Overview
PartsMine 18650-PC8 is an 8-pin through-hole battery holder designed to secure four 18650 cylindrical cells directly to a printed circuit board. Each cell compartment features two dedicated solder pins that remain electrically isolated from adjacent bays, allowing custom series, parallel, or balanced circuit routing directly through board traces. Molded polarity symbols and series-parallel alignment guides inside each compartment assist with correct cell installation.
Key Features
- Accommodates four standard 18650 lithium-ion cylindrical cells
- 8-pin through-hole PCB mount with two dedicated solder terminals per cell position
- Electrically isolated compartments allow independent trace routing for series, parallel, or multi-tap configurations
- Nickel-plated spring steel leaf contacts provide firm mechanical retention and electrical connection
- Molded thermoplastic housing with polarity indicators and dual English/Chinese series and parallel guides
- Eight integrated base holes for optional mechanical fastening
Applications
- Soldering directly into custom uninterruptible power supply (UPS) and battery backup boards for microcontrollers and single-board computers
- Building series-connected battery packs with external BMS boards for robotics and portable instrumentation
- Prototyping parallel cell banks for off-grid sensors, solar loggers, and field radio equipment
Frequently Asked Questions
Are the four battery slots connected internally?
No. All four compartments are completely isolated. Each slot routes to its own pair of through-hole solder pins, allowing series, parallel, or individual balance connections to be established via PCB copper traces.
Are 18650 batteries included with the holder?
Not included.
Does the pinout match the standard BK-18650-PC8 footprint?
Yes. The 8-pin through-hole layout and outer mounting hole pattern align with standard 4-cell 18650 PCB footprints, including the MPD BK-18650-PC8. More pieces cost less each - the price-break table on this page shows what each quantity costs.
Four isolated bays leave the circuit architecture entirely up to your board layout instead of a pre-wired strip. Drop in your cells, solder the eight pins home, and power the project your way.
