[QUOTE="hispls, post: 8593197, member: 614752"] Agreed, just bear in mind you're robbing Peter to pay Paul buying very expensive Lithium battery to power inefficient amps and drive inefficient speakers. Give it a whirl and if battery life is an issue when you actually get down to whatever real-world application you're doing you can decide from there if switching gear is cheaper than buying another battery and if you can spare the size/weight of another battery. Keep in mind, people who build studio monitor type bookshelf speakers for the home to be run on tube amps (perhaps 50 watts per channel) will pick very efficient speakers that will get loud on lower power but wouldn't handle 100W without burning up. I'll wager those portable radios that are powered by a 14V tool battery use speakers that couldn't handle 20W but sound reasonably loud on the 10W the portable battery can make for a full work-day. Really depends on your priorities which way you should go. [/QUOTE]
