Neu LiPo vs. Maxamps 5000mAh packs

Anyone have any eagletree data? I was out with 6s (2x3s and a Y harness), 20C, 5000 mAh maxamps batts today in my MGM 16018 / Neu 1521/1Y maxx. I was surprised to see that I was only able to draw about 1000 watts (~50 amps at 20V, which is about 3.3 V/cell under load).

The good news is that I started checking the setup and discovered a really, really bad solder joint in my homemade deans Y-harness (here's to the do-it-yourselfer working with 12GA wire and lots of deans connectors :). I'm going to patch that up and measure the difference. After that though I'm going to switch to a pair of thunderpower 3s, 25C, 5000mAh packs - I believe those are the enerland cells based on the (bigger) size compared to the maxamps.

I'll post the graphs up asap (damn that day job), but was really hoping some others would have comparable data to share for comparison / reference. (not necessarily just for the batteries, but 1521 vs. 1515, etc.). It'll be fun to sort all this out.
