If the problem is the high voltage does anyone know where I could get the right voltage rechargeable batteries with decent storage. I would like to stay away from voltage regulators.

You could use 2 packs of 4 AA or AAA batteries connected in parallel. 4 of those batteries connected in series will be about 6 V and 2 packs of those in parallel should give you enough power to power 5 servos at once without changing the voltage

I would advise against using normal alkaline batteries. Battery packs are a much better alternative because they can be recharged and you will never have to buy another pack (at least for the season). 6V battery packs are sold in high current capacities.

I agree. Also, a battery pack of 4 C or D batteries would also work better than AA's since they are very high capacity, but rechargeable batteries are preferable.

Not to mention it would be extremely expensive to keep purchasing batteries

We are using rechargeable batteries, so the only inconvenience is having to recharge them relatively often
