Any recommendations for portable 12v batteries?

Could you recommend a 12v battery that is:
- light weight
- 6Ah or more
- quick charging
- long lasting
- preferably comes with a mains charger.

Will be used to power a portable audio system.

BTW: Anyone have experience with such suspicious looking solutions as http://www.discoverybargain.com/product/EB00185L/T-1298A_DC_12V_9800mAh_Super_Capacity_Rechargeable_Li-ion_Battery_(Blue)_29525.html ?

Has anyone ever heard of Yingshita Technology co?
Found some larger capacity lithium batteries on their site, but don't know if they can be trusted...

I have ordered and tested the YSD-12900 Li-Ion rechargeable battery pack and it does not meet the specification as listed by the manufacture. On a fully charged battery pack I put a 500 ma load on the battery and it was depleted within 6 hours time. I should have gotton18 hours with that load.
I ran this test 4 times with the same results. The battery pack does not meet spec and I would not reccomend using it for equipment that has a heavy ciurrent draw

That would have to be a battery pack or lithium battery.
