I came upon an interesting comment about batteries at the web blog of Cosmonaut Maxim Suarev which is in English at Russia Today:

The blog was from someone working on a Peruvian cubesat called CHASQUI-1. The specific question is:

"Lizeth Bodero 10 February, 2010, 14:24

hi!! I'm a science student and here in my University we are building a nanosatellite named "Chasqui". We hope to launch it this year but there's a problem with the batteries since we wanted to use lithium polymer batteries and we don't know if those are allowed by the Russian Federal Spacial Agency. Do you have any suggestion about that? thank you so much "

Someone on the group might have the answer? Looks like they have already identified a launch vehicle...

There are wiki entries and a web page for CHASQUI-1, although the onboard comms system isn't described here is a description of the ground station:
