Cheapest/safest way to charge 6V NiMH battery pack

Hi,

I’m looking for an inexpensive way to charge a 6V NiMH battery pack. Anyone have any good ideas? (inexpensive because its for a project with a budget)

Thanks,

Where can we get 6V NiMH Battery Pack? I will be also needing this for our electronic device. Thanks.

You can inspire yourself from this project. It is not for a 6V battery but the components required are very similar:
