Batteries & Power supplies

This lithium-ion battery is small, light and durable. Through standard JST 2mm female connector, it will yield 3.7V which will supply your projects for a whole day (and night!). Furthermore, the battery has an implemented protection system, which prevents high voltages ( prevents over-charging), undervoltage and short circuit. That way it protects the battery, increases its lifetime and protects you from possible accidents!
