Help with powering setup

[Wifefang]

Hiya to all, I have a few questions that more experienced members may be able to shed light on, or someone who has a fair understanding of electronics, as my understanding is somewhat unlimited.

My current setup uses the enhanced motordrive form skywatcher. DC motors rated six volts. I have just started autoguiding and am aware that my Duracell batteries run out very quickly. Is it possible to use rechargeable batteries now that auto guiding is rigged up? My concern is that the batteries are 1.2volt rather than 1.5volt. Is auto guiding able to make up for the under voltage or would that be a massive waste of time or worse destroy my motors? 

A better solution or any solution to this power dilemma would be greatly appreciated.

Thanks for reading

The Skywatcher 6V motor systems should run fine on the 5.2V output from a mobile phone /tablet battery bank, I use a 10AH one and it runs for ages, you will need to make up a lead though using an old USB cable and a DC 5.5 mm connector but cant remember if its 5.5mm x 2.1 or 2.5mm.
