18650B Battery Grip for Lumix GX800(GX850, GF9) Capacity: approximately 7000mAh (dependent on batteries - over 1800 normal shots tested, no timelapse, though a few tenths of thousands have been tested for timelapse). !!!! If it's not working after assembly, charge it to balance cells voltage, then it should work just fine !!!!! You can't change the SD card while it is mounted, because the cable from DMW-DCC15 blocks the battery lid. Please report any problem. <h2>Things You Need</h2> 4x NCR18650B li-ion batteries 1x 1/4" x 16mm bolt (hex head 11mm) - 16mm= thread length, 20mm= whole length 1x 1/4" insert nut (8X9mm) <b>OR 1/4" hex nut 11mm head and 5.5mm height</b> 8x M3 insert nuts (5x6mm) 8x M3x12mm bolts 2x switches (MSS22D18 ) 1x 2s capacity indicator 1x 2s 18650 battery protection board 4x pairs 18650 battery contacts 1x DMW-DCC15 (BLH7 fake battery) 1x micro USB MT3608 DC-DC Adjustable Boost Module 2A (adjusted to 8.4V) -!!!!READ IMPORTANT INFO!!!!! <h3>For 1/4" insert nut version, you need only "main_bottom_rev5"</h3> <h3>For hex nut version, you need these parts "main_bottom_rev5hexnut" and "hex_nut_cover"</h3> Some wires, epoxy glue, and hot glue Some (not all) battery contacts must be trimmed because there is not enough space. No big deal - just corners. You may need to trim the spring for the battery that's lying under the lens. <h1>!!!!!!! IMPORTANT !!!!!!!</h1> <h2>!!!! DMW-DCC15 !!!!</h2> You have to modify DMW-DCC15 contacts or the camera won't use this battery pack and there will be an error message. See the picture! You don't have to grind it like I did; just grind out the section in that red rectangle. The length of the cable from the fake battery to the main body must be at least 85mm to ensure easy connections. <h2>!!!! washers !!!!</h2> If you use thicker wires or there's not enough space for them, you can use washers - "1mm_washer_pt1" and "1mm_washer_pt2".
