battery clip

基本解释

Rugged nickel-plated copper clip leads won't spark when initially attached to a battery to reduce the possibility of an explosion.
坚固的镀镍铜夹引线时，不会引发最初连接到电池，以减少爆炸的可能性。
It is self-contained within the body, powered by an internal battery, which is itself recharged by a clip-on external battery pack.
它是在人体内部独立运转的，其动力为一节内置电池，它由一段外置的电池包来提供充电。

This means you're always relying on wireless connectivity (more on that in a sec) but also that you've always got a battery ready to go, and it's admittedly pretty neat to rip out that battery (like a clip from a gun) and slide a fresh one in.
