[MarinTeams] Portable Battery Pack technology

[Bill Smith]

No endorsement, but thought you might be interested in what may be the
"latest technology" regarding battery supplies.
And yes, the QRP-labs model QCX QRP CW transceiver is the latest project
here; built the 40 Meter version which works very well.
I don't have a battery pack (or a case) for it, yet.
