im not sure if they weld it. laser cut and maybe folded and rivited? I dont l know much about stainless grades. so no idea. had wondered i guess ill just ask. each question takes ages to get a reply. hmm
0.98mm stainless steel or 1.2mm steel? Same price. Getting a battery box made by amys supplier.
Box size L580mm * W300mm * H360mm.
Box is so big because i was leaving room for 5cm thick Pir insulation i have for UK cold nights and recharge in morning use.
