At 100w you should be good with the Samsung 30Q batteries which are 3000mAh, but pushing up closer to 160w could work the batteries harder then they should be. VTC4s are probably the best all round batteries for these devices be are only 2400 mAh.
You should check out Mooch's blog and ask the question in the battery forum if you want some more advice.
Thank you, I most certainly will.
