Hey folks, I'm having a few issues getting my head around replacing a small battery pack I have. The pack in question is simply labelled "Ni-MH 3H260BC 3.6V +". Here it is, I've removed the outer wrapping to reveal the layout: It comprises three Vinnic H260BC batteries. Now I have three problems. Firstly, it looks like this is a bespoke layout. Secondly, I can't seem to find a UK source for replacement individual cells. Thirdly, how the hell does the soldering work on the surfaces of these cells? The strength of attachment is awesome. I'd really like to source a pre-assembled replacement unit (using similarly rated alternative cells). I figured some of the RC crowd on here might know quite a bit about this stuff. Any help much appreciated, it'd be great to get this secret item working again after several years.
