I was planning to get a battery pack and charger for my xbox 360 controllers but I was wondering if it's worth and what the battery life is, or if it's better to just get a battery charger and rechargeable AA batteries.
its around 25 hours per Charge, It's a great buy unless you have multiple controllers you might want to get some third party controller stations.
complicated issue. look using a search engine. it might help!
dont use those. get a battery charger and some duracell nimh rechargeable batteries 2000mah and up. you wont regret it.
