Frequently Asked Questions

Q: Are 18650 batteries included with the battery storage box?

A: No, batteries are not included. The package contains 1 or 3 battery holder(s) depending on your chosen quantity option. Standard 18650-size lithium-ion cells are widely available and fit securely in these holders.

Q: Can I connect multiple battery holders together for higher voltage?

A: Yes! Thanks to the pre-attached wire leads, you can wire multiple holders in series or parallel to achieve your desired voltage or capacity for DIY electronics projects. No soldering is needed to get started.

Q: What slot configuration should I choose for my project?

A: It depends on your power requirements. A 1-slot holder provides ~3.7V, two slots in series give ~7.4V, three slots ~11.1V, and four slots ~14.8V. For higher capacity (mAh) at the same voltage, wire holders in parallel instead.

Q: Is the ABS plastic housing durable enough for workshop use?

A: Yes. ABS (Acrylonitrile Butadiene Styrene) is a tough, impact-resistant engineering-grade plastic commonly used in electronics enclosures and DIY hardware. It holds its shape well and protects your cells during both use and storage.
