Early on in the development of the BHDAC we started playing with battery power, with nice results. Even with all of the sophisticated regulation in the DAC itself the battery seems to improve the dynamics a bit over the stock line lump. While we felt the DAC itself was not workable as a kit, we do plan to produce this battery supply in kit form. It will come in a cabinet similar to the DAC but wider and deeper. It will contain a 7AH battery that might give about 8 hours of play on a full charge, and a charging circuit that will allow the DAC to play on battery with the charger off, battery with charger active (in case you want to run the DAC for hours and hours at a very slight reduction in sonics) and charge only (DAC turned off and faster battery recharging).
The line lump that comes with the DAC will plug into the battery supply chassis and power the charging circuit. The battery supply will then plug into the DAC, which can sit beside or on top of the battery supply. We hope to have some photos of a prototype supply by early June. Price is TBD. I hope to have a ballpark figure later today.
