You may want to check out the GensAce batteries at hobbypartz http://www.hobbypartz.com/98p-25c-3300-4s1p.html. I have never used one but they have excellent writeups over on Rcgroups.com.
Great find Will, Based on general specs these appear to be OEM (private label) versions of Turnigy and ZIPPY brands from HobbyKing. I am currently using both ZIPPY and Turnigy with good results. The big problem is freight from places other than USA. As soon as I saw this post I ordered several for evaluation. Thanks again
Dwayne,You will probably be fine with that, but if you were buying from Hobbyking, and had to get 3000mah 4 cell why didn't you get this one at 2 3/4 ounces lighter http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=11920. You could have gotten their 3300's when they got them back in stock. The 25c weigh an ounce less http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=11924 . The 35C weigh almost the same http://hobbycity.com/hobbyking/store/uh_viewItem.asp?idProduct=11950.The Gens Ace batteries I mentioned a few posts up were 3300's but the listed weight was also the same as the ones you picked. I know the shipping is free on those at least in the US. I do realize that shipping to Canada may have played a factor in your decision.
