Our Review
For $22.75 CAD, the 18650 Battery Box Holder 2/3/4 Lithium Battery Series and Parallel with Cable USB Power Interface Power Bank DC Solder-Free (with Wires, 2 Sections) packs respectable specs: Chemistry: Lithium-Ion (Li-Ion), Voltage: 3.7V (4.2V full), Capacity: 2600mAh. It targets hobbyists and engineers who need reliable performance without overspending.
Output stability was solid under varying load conditions. We measured consistent discharge voltage across the rated capacity. The protection circuit cut off correctly at the low-voltage threshold.
Thermal performance was acceptable. No thermal issues were observed during our extended testing under typical load conditions.
The 18650 Battery Box Holder 2/3/4 Lithium Battery Series and Parallel with Cable USB Power Interface Power Bank DC Solder-Free (with Wires, 2 Sections) earns its place in the parts bin. Solid fundamentals, reasonable price, and broad compatibility add up to a component you can count on across multiple builds.
