Galaxy Tab S 8.4 SM-T700 Replacement Battery

I'm wanting to have a go at replacing the battery myself. I've googled & came across battsrus.co.nz & fonefix.co.nz, but some of the other sites I've found look a wee bit dodgy ie. they have a wee NZ Flag icon & Currency selector in the top right hand corner which makes me think it's an off-shore shop regardless of what their "About Us" page say.
