Cells are -14.1mm x 50.6mm and the charger is a Ripmax Pro-Peak Prodigy
I just did a very silly thing and measured the cell length with my micrometer without thinking about it, it's not something I've even considered doing before...ooh yeah the whole things metal. I was measuring the near dead cell so no worries, but I thought I would mention it just as a reminder to anyone else who's joining in :)
