My old Battery Pack failed on me and was close to causing serious damage. But thankfully I noticed the problem early enough and stopped using it. The problem was a badly made spot welded connection. This got me thinking......do we really need to spot weld battery packs? I mean, it requires extra equipment and you can not easily repair a spot welded pack. So in this video, let's explore some spot weld free battery pack alternatives. Let's get started! ;-)
