Often when a photographer is right in the thick of the action, the last thing they need is performance fade or to have to stop mid flow to change the batteries. Created specifically for the A1, the Lithium-Ion high capacity battery lasts up to four times longer than cumbersome AA batteries with no performance fade, it clicks on and off the A1 in seconds, and can be recharged quickly. So you can shoot for longer with confidence.
And our Li-Ion batteries are UN-certified so you can take them on a plane, no matter what your destination. All the documentation you need can be found under the download tab.
