About this product
Overview
Cutting the umbilical is often the last step in a project, and this set makes it simple. Each of the five 9 V battery holders comes with a long-life alkaline battery already included and terminates in a 2.1 × 5.5 mm DC barrel plug — the same connector an Arduino UNO, Mega or ESP32 expansion board expects.
The batteries carry a five-year shelf life and leak-proof construction, so a spare left in a drawer is still usable when you finally need it. That makes this set as useful for cameras, camping gear and emergency kit as it is for the workbench.
