The Vello BC-N1 Battery Chamber Cover is a replacement battery cover designed to work specifically with the Vello BG-N1 and BG-N8 Battery Grips. This cover clips onto the battery, keeping it securely in place. If the batteries are removed from the grip for charging, the cover keeps the grip clean and free of debris.
In addition to being compatible with the Vello battery grip, the BC-N1 can also be used with the Nikon MB-40 and MB-D10 multi-power battery packs for the ENG-EL4 and EN-EL4a batteries. When using the BC-N1 with the optional EN-EL4a battery, faster continuous shooting speeds of up to 8fps are possible.
