As long as you use them in parallel (all positives connected together, all negatives connected together), then yes, that would work. As the batteries are never perfectly matched or balanced, I would recommend you use batteries that have protection circuits on them, or add some (they're really cheap on ebay). This will ensure that no single cell is under or over discharged. This may be being over-cautious since when the cells are paralleled up they are effectively one battery, but it just prevents any nasty things happening, and at around $1 a board, the protection circuits are worth that extra peace of mind!
