HobbyKing has recently updated their web site making it more difficult to hone in what you are looking for. I was trying to see what was available for 4s lipos, but it was so convoluted that I became frustrated and gave up. Before the web site update it was a simple task to filter 4s lipos and have a long list of what was available shown on the page to see what was available. Now you have to use several sliders to filter with and there are only a few listings per page. You have to go through numerous pages to see what is available.
