thanks A-team. if i ask a return, i am aairfd i will get the same product. when i read the instruction manual included in the bp-d10 box, they write that the following items are supplied in the d300b at shipment:the grip d300B, en-EL3 battery magazine, AA batteries magazine, car charger, contact cap, infrared remote control device. They said as well that the BL-3 battery chamber is required when using EN-EL4. ( purchase separately). it means that the instruction manual fits the box content. I wonder if aputure has not made 2 bp-d10 product at some time . one with the el-en4 with no car charger and remote device and later on change the content by removing the el-en4 cover and add a car charger and remote device. thanks
