Those have a 20 amp limit, and you're running at very low ohms, .27 makes it a 15.5 amp draw, if your ohm measuring tool is off by even 0.1 ohms (which is a very reasonable calibration for most applications) you're draw could be 25 amps.
If you're dead set on building that low, buy some sony vtc4's or wait for tests on those new efest 35 amp batts.
As it stands you're basically jumping up and down on a bridge that says 200 lb limit and you're 190.
These battery specifications are not consumer ratings, they're manufacturer ratings, and they expect the user of the battery to build in their own threshold for safe use.
Be careful..
