<p>I know some packs but budget is the first concern.<br /><br />If your range is $1000 above you can use ranger, Profoto packs<br /><br />If you want to use Lithium try Godox brand LP 800<br />http://www.godox.com<br>
Innovatronix offered SLA Battery, much cheaper and I have their old version XT 1200WS.<br>
Tronix Explorer xt3 is the latest version with 800watts<br />http://www.innovatronix.com/index.php/webshop</p>
