Hi djozz, thanks for the replies!
Sounds like trouble. If I find a way to secure the magnets so they cannot shift, are there any other issues I should consider, such as electrical resistance of the magnets, etc.? Or is there a generally accepted “better way” to install buttons on the top of flat-top batteries? Or are the best batteries for this light readily available as button-tops?
I find it hard to believe any promises made by sellers of China-made products these days. Having said this, the seller claims to be in the USA, and the description makes a serious effort to boast about their protection technology, and they are offering an 18-month warranty … so I would guess that they probably do offer built-in protection in this light.
So you’re saying that if this light is not engineered to handle the current available from high-drain batteries it might “melt down” or “explode” or self-destruct in some other way? Sorry if this is a stupid question.
