Hey, Ive bought some cells but they wont be here for at least 2 weeks. I want to be as kind as possible and heat the cell as little. Would a decent technique be to tin the battery bar ends, then add flux to the cell top , melt the solder on the bar and then put on bar so less heat transfers to the cell?
As for flux, where can I buy some, maplins do it only in a pen and its nearly a fiver!
