Voltlog #227 – Identifying Pure Nickel Strip vs Nickel Plated Steel

Welcome to a new Voltlog, if you’re a frequent viewer of my videos you’ve no doubt seen me build this spot welding machine that I use occasionally for building battery packs for my RC planes. I use this machines to create nice welding spots between nickel strips and the battery contacts. My battery packs do not exceed 20A passing through and that’s only in short bursts but there are people building higher current battery packs and so it’s important for them to be using pure nickel strips instead of nickel plated steel strips for making the links.
