Woot woot! DIYAudio member Raptorlightning has successfully implemented a USB-charging single cell lithium battery pack in the Pocket Class A! The amp can also run directly off USB power with this setup--a major benefit IMO.
He used a LiPo cell and three small circuits: an off-the-shelf boost converter board, a custom load-sharing board with a micro USB power input, and a tiny custom cap multiplier board that keeps the battery from going into auto-protect when the big capacitors charge up at turn on.
I'm hoping to do the same for my builds as soon as I fully understand his approach.
Hoo Yah. That is what I have been awaiting. Need to explore this big time.
On insane clown mode. I have an almost irresistible urge to go old school with this design and do a point to point wired version. I will consult a therapist obviously before going there, but still....
On heat dissipation. There are several great choices out there readily available at most large hardware retailers. Begining with aluminum paint available at Home depot, to hammertone copper, Krylon Silve and gold plate. A lot of the above mentioned were pioneered in the laptop trade as coatings to inhibit rf interference and somewhat alleviate the heat generated by high clocked cpu's in an enclosed space.
