The Anton Bauer ElipZ 10k Battery Kit for Canon
under-camera mounted lithium ion battery offers excellent run time to handheld 7.2 volt battery operated cameras. Using high capacity lithium ion cells, the 75Wh 10k can provide runtimes as much as 2 to 5 times that of the consumer OEM batteries supplied with the cameras. On a 10 watt camera load, the 10k will run over 7 1/2 hours, virtually a full shooting day! This kit comes with charger and connectivity for Canon's GL-1/2, XL-2, XF300 and XF300P.
