New Zealand parts advice

[Emma]

Hey everyone,

I was just wondering if there were any NZ cavers who have built a Caveatron? 

I am trying to source parts and finding it difficult to find a suitable battery pack. Unfortunatly it is very difficult to import batteries into NZ so are there any alternatives I can use to power the RevC with LIDAR model? 

I am a complete electronic novice so any guidance will be greatly appreciated.
