Meike SD-8A is powered by 6 AA or standard batteries. It should be said, that flash has to be charged as well, battery pack provides only additional charging. We recommend to use the same batteries both in battery pack and the flash. Red LED diode informs that the flash is being charged from the battery pack. NOTICE: you should not take more than fifteen flashes in one series, as it can burn your flash. After such a long series, you should take some time to cool your flash.
Battery pack Meike SD-8A may be mounted under the body thanks to the tripod thread. Connecting the device is really simple, just insert the batteries according to a drawing on the cover, connect it to the flash and turn the flash on. Additional charging will be instantly detected by the flash.
