I've read a couple of posts that the stock charger charges at 2-3C vice the recommended 1C - so that would mean the battery life could be shortened ( as I understand - I'm not very charger-literate). So if the mod in this thread shortens charging time by 1/2 of the stock, it looks like the charge rate has to be higher than the stock - meaning there's a very good chance of shortening battery life?
