I've got the robostix, verdex-xm4, and netwifimicroSD.  For now, I'd like to just power everything with 4 Tenergy 2300 mAh nimh cells that I already have.  I have a battery case with a 2-wire lead and a small JST/BEC connector at the end.  I will replace this connector with the proper female connector found on the wall adapter (CUI Part number PP-012).  Is there anything else I should be doing here? The battery page (http://docwiki.gumstix.org/Batteries) suggests that a supercap might be needed.  Is this necessary? Is 4.8V enough to power all 3 boards through the power jack on the robostix?
