This has my vote for this application also. You need a minimum of 12 amp continuous available from the battery. This is the link from Stosh's post #3 above;
Preliminary testing with the DNA30. Check out what Mamu says. She knows what she's talking about and likes both the LG 30A 18650, or the Sony 30A 18650.
The VTC5 is actually 2600 mAh, so you're not losing much compared to a 2900 mAh battery with less amp draw capability and if you're using the DNA30 at higher power you might actually get the same or a bit more time from these batts.
Buy from a reputable supplier and you will have one of the best batteries you can get for this mod.
