PM sent to the OP.
I am still making Mardave battery enclosures in case anyone was wondering. Emails must just have hit the spam filter or not been received. The Kamtec batt holder is fine but suits only 6-cell subC style packs, not the small LiPo packs that are so good for the Mardave. Also it's just a tray and has no way of keeping the pack in. If you want a weight-balance adjustable bomb proof solution then the Full Option enclosure is the best you will find even if I say so myself.
Also I would recommend considering an MKS HV servo. These are the fastest I have ever seen and the nicest made, but will cost you twice the price of a V12 kit unfortunately:
