I bought two 7 cell 4000mah, Emaxx pacs of these cells and they frankly are my worst pacs and I've been real disappointed in them. New, they would only charge to a little over 3000mah and now after 15 or so cycles have improved to 3200-3400mah.

I have other 4000mah pacs (Maxxamps) and when they were new that would reoutinely charge to 4400+mah. Now that they have 50-70cycles (don't know exact number, lost track) they still are charging to 3600+mah. I won't be buying any more Tenergy cells. I guess there's a reason they're cheaper than everybody elses cells.
