I believe the blue wrapper batteries are smoore originals, I do have a SLB 401 here, the box at least, but I can't remember if those batteries come in a blue wrapper, I don't think they do though.
SLB M40x auto batteries do not always work with Smoore M40x atomizers, the light will activate but the atomizer will not heat up, I would say 50% of the batteries do this. How do I know this? I bought a load of smoore atomizers as they are better than the SLB M40x atomizers and a load of SLB m40x auto batteries as genuine Smoore autos fire a bit easy so I wanted to make the most reliable M401 kit but it didn't work out that way. In the end I had to return all the SLB M40x auto batteries and ship in Smoore M40x manual batteries in. So, those two M40x's are not totally compatible. The batteries are hard to tell apart but the atomizers, whilst having the same thread, are easy to spot, the SLB bridge is thinner and comes to a point more than the smoore goods. You probably want the smoore atomizer and thus a smoore manual battery, from my professional opinion.
I am quite sure that HG sell only smoore goods.
Oh, one final point, the SLB M40x parts are a lot less expensive than the smoore parts
