Overview

Product Overview

2 x 18650 battery holder box is a compact power solution for mounting and connecting two 18650 lithium-ion cells in DIY electronics, robotics, and portable prototyping projects. The 4-wire battery holder design gives you flexible leads for integrating with chargers, power management circuits, switches, and custom battery-powered builds, while the no-cover open holder format makes cell installation and replacement quick. Ideal for Arduino, Raspberry Pi, ESP32, LED, and embedded hardware projects, including home automation nodes and portable test setups, that need a secure dual 18650 battery box for reliable bench or mobile power.

Questions & answers

Frequently asked questions

Yes, it can be used as a battery source for Arduino, ESP32, Raspberry Pi, and similar embedded projects when paired with the proper regulator, protection, and charging circuitry required by the board and batteries.
The holder has attached 4-wire leads, so it can be wired into a charger, power management board, switch, or load without soldering directly to 18650 cells. You may still need connectors, insulation, or circuit soldering.
The 4-wire design provides flexible leads for integrating the two 18650 cells with chargers, power management circuits, switches, or custom wiring. Always verify polarity and the intended cell configuration before connecting it to electronics.
Yes, the compact open holder is suited for portable prototyping, robotics, LED projects, home automation nodes, and test setups that need removable 18650 cells. The no-cover format makes cell changes quick during development.
Check that both 18650 cells are charged and installed with correct polarity, the metal contacts are touching cleanly, and the downstream regulator or power circuit is wired correctly. Also confirm your load is compatible with the battery setup.
