Honestly, I don't think you want that charger, I believe what you already have is better than that one. The one in your weblink is a timer charger, but it doesn't charge any fast than any other kind, it simply shuts off after the timer runs down(kinda like a windup toy, in a way), but its charge rate is no higher than what you have now. So in truth, you'd just have to keep restarting that timer one & you'd also have to keep a VERY CLOSE eye on the voltage of your pack, because it doesn't have any kind of voltage peak charge to it(so if your pack peaks but the timer hasn't run down, it'll just keep going & destroy your pack).....
