DIY HID light help

[sputnik]

Hi friends
I'm starting to set in motion my plan to build my first 21W HID canister dive light.

I'm looking into buying either one of these batteries:

and one of these chargers:

what is your take on using these parts?
any feedback would be great.
my e-mail is info@vjsputnik.com
Thanks
Doron

Any of your choices should be fine, but you may want a lower amp rating battery pack if your not doing deco dives. A 5000mAh pack for a 21W HID should last around a couple of hours, + a shorter recharge time, and smaller. Check out this thread for more info: http://www.scubaboard.com/showthread.php?t=129065
