If I had to guess, I'd say those are 2C cells and they may or may not have a low enough DC resistance to power a DNA30 to the maximal 12 Amps it can demand. The cells are at least 2C and with 3800mAh, that gives them a continuous drain limit of 7.6 Amps. Burst limits are safe for 3C with a 2C cell so that gives you a burst limit of 11.4 Amps.

You can get an idea by measuring the cell's voltage drop under load. You want to check using a fairly heavy load. You can use something like a 25 Watt 1/2 Ohm wirewound resistor or a 1/2 Ohm atomizer.

You need two meters. First a 10A ammeter inline to measure current and a voltmeter on the battery terminals. Measure voltage with no load then measure voltage with a fairly heavy load. Divide the change in voltage by the current and you'll get the DC resistance of the cell.

You probably need to see a DCR no higher than 25 mOhms when the cell has a good charge on it. I have some small LiPos good for 14 Amps continuous and that's what the DCR is on those.
