Tip: For Li-ion/18650 projects, use a proper protection/BMS board and a regulated 3.3V or 5V output before powering your microcontroller and sensors.
Battery holder chooser (quick guide)
| Need |
Good first choice |
Notes |
| Small portable Arduino/UNO project |
4xAA holder + 5V regulator |
Simple and widely available; good for breadboard demos and student kits. |
| Low-power sensor/logger node |
2xAA or 3xAA holder + efficient buck/boost |
Great for slowly-sampling temperature, soil moisture, or environment nodes. |
| Wi-Fi/LoRa ESP32 field node |
1x or 2x 18650 holder |
Pair with a Li-ion charger/protection and a 3.3V regulator for safe, longer runtimes. |
| Robots with DC motors |
4xAA, 6xAA, or 2x18650 holder |
Use a dedicated pack for motors, share common ground with logic to reduce noise/brownouts. |
| Wearable/prop lighting |
2xAAA or coin-cell holder |
Lightweight option for a few LEDs or a tiny microcontroller, watch overall current draw. |
| RTC backup / ultra-low power |
Single coin-cell holder (CR2032) |
Ideal for clocks and backup memory where current draw is in the µA range. |
Values and picks are common starting points; always confirm your board’s input voltage/current requirements and regulator specs.

FAQ
Can I power Arduino/ESP32 directly from a battery holder?
Yes—just make sure the total battery voltage matches what your board or regulator expects. Many Arduino boards accept 7–12V on VIN, while ESP32 boards usually want a regulated 5V or 3.3V input.
Which battery holder is best for small robots?
For typical 2WD/4WD educational robots, a 4xAA or 6xAA holder or a 2x18650 pack is a solid starting point. Give motors their own pack when possible, then share GND with the logic supply.
Do 18650 holders need extra protection circuits?
Yes, Li-ion cells should be used with a BMS/protection board and a proper charger to avoid overcharge, over-discharge, and short circuits. Treat 18650 packs with the same respect as a small power tool battery.
Can I mount these holders inside 3D-printed enclosures?
Most holders have flat backs and/or mounting holes, making them easy to screw into or glue inside 3D-printed cases. Check each product page for dimensions when designing your enclosure.
Do you ship nationwide?
Yes—Circuitrocks ships battery holders and related parts anywhere in the Philippines, with fast processing for in-stock items.
