I discovered this morning that Turnigy appear to have discontinued the 2s and 3s battery packs that I had standardized on. I will be reaching out to them later today to get definitive word on whether or not they intend to replace them, or if I’ll have to find another source. For now, unfortunately, LiPos are limited to stock on hand. I have set the shopping cart so that if a battery type is out of stock, it will not allow you to order it. This includes starter kits that include batteries.
