I do love the way everything anyone says here has to be qualified....
So I picked this pack because it is the same pack as used and retailed through a company as part of a complete product - in this case an expensive mobility device for wheelchair users.
This means I have both the original, fully EU certified pack and the ones I ordered directly, and to satisfy myself for all the reasons raised here, I opened and inspect both.
They are literally identical.
The connections ARE all nickel strip and the construction is very tidy.
Both the original and directly imported packs all use genuine Samsung cells, and as I’ve used and cycled all the packs I have monitored their performance and have no hesitation in recommending them.
I’m sure there are horror stories out there, but my experience with these particular packs, from this particular maker, have been 100% positive.
