Default Auxilliary battery

I want to replace my e250's internal battery with a higher capacity external pack consisting of at least three NiMH C cells, which should give me about 5,000 MAH and 168 hours of uptime.

I want this setup for community noise data collection where I will log decibels at 1/8 second intervals. I will also record PCM clips of high-noise incidents. I will need to create a RockBox variant for this. I will want to run this application for 24 hours up to a full week unattended.

Should I remove the existing battery? Seems like if I leave it in place, the auxilliary pack will be pushing current through trying to charge it, wasting precious capacity.

Can I even remove the existing battery and then attach the external setup through the USB/dock connection? And if I do this, will I need to use four cells instead of three to bring volts up close to the 5v USB standard?
