Canon LP-EL Lithium-Ion Battery Pack

The Canon LP-EL Lithium-Ion Battery Pack delivers the power and reliability needed when shooting any situation especially weddings when a moment can be once-in-a-lifetime, so you can feel comfortable shooting over and over for extended periods of time. You can even view the remaining battery level in the top right display of the Speedlite EL-1 letting you know just how long you can go or when it's time to recharge with the LC-E6 battery charger.
