8ight-e (tekno) w/ Medusa v2 60mm 2000kv Neu or Maxamps lipos??

[stum]

Ok... So Im running my 8ight w/ the tekno v3 conversion, currently with a mamba max esc and a medusa v2 60mm 2000kv motor and 4s lipo's. I want to pick up a 4s single pack and I have two choices.

1) Neu Energy 25c 5000mAH 4s (little or no warranty)
2) Maxamps 20c 6000mah 4s2p w/ 3yr/300 cycle warranty

Same exact price.. so the question is will the MA 6k hold up to the draw of this system w/o a puff.

Thanks
