Batteries for Engel Akula - Batteries?

[libor]

Hello,
have question - which batteries shall I use in Engel AKULA (main)? They do not support main batteries for Akula, and I am not sure what to choose from the net. What do you recommend?

Just putting in my 2cents

Just putting in my 2cents worth, I get my batteries from Tech R/C , www.techrc.com. They have a large selection of pack configurations, or can custom build if you don't want to try to solder up your own packs. Hope this helps, I used to build all my own packs to fit the space requirements, however, it seems to be a bit less costly to buy premade packs than individual cells and build your own.
I am thinking you will need 4 5cell/ 2 10cell or some other configuration to achieve the 12 volts? required.
