Battery powered amps

Anybody have experience with battery powered amps? I am specifically intrigued by the Red Wine Audio products. They have a pair of 70 watt mono blocks that run totally on battery power. Six Moons has reviewed these (and RWA's 30 watters) very favorably. At 70 watts, they should be capable of driving a fairly wide range of speakers and in reading up on the technology they seem to be fairly low maintenance. Of course, recharging is an issue, but it looks like these amps will go 6-12 hours on a single charge. That would satisfy 95% of my listening requirements. Considering how much time, effort and expense that we audiophiles spend trying to tame the AC powering our equipment, battery power is very intriguing since it removes that evil altogether. It looks like RWA also has a tubed battery powered pre-amp/DAC in the works as well. Cool stuff, but I would be interested in real world experiences.

TRL is Tube Research Labs. They make custom built tube and solid state amps/preamps, as well as modify audio components, especially digital gear. You can contact Paul Weitzel at 509-787-5405.

As a point of reference I own the D-225 amp and Pre-1.5 battery powered preamp they built for me, as well as a DAC they modified. I've also got some power cords and speaker cables they made as well, which used to be sold under the FIM, then later CRL brand (not to be confused with the new CRL brand being sold).
