Anderson connectors: if too small, is that a bottleneck?

The Original Poster made referral to his 'Portable Panel. I doubt all the concerns over voltage drop through a connector for a 100 or 200W panel is going to be significant loss under any circumstances. Further, I stand behind my recommendation for not using Anderson Power Pole connectors for this situation. They are simply not that physically robust or weatherproof. The Zamp 2 pin connectors would be the better choice.
