Hi,

You might look into just building a battery... it's just a bunch of cell's soldered together. There's lots of tutorials / examples from either the RC world or the HAM Radio world.

Or googling I found for example www.cheapbatterypacks.com CBP Custom Pack Builder which makes custom packs, just select your various configuration options!
