[QUOTE="Art Welter, post: 208585, member: 52"] Ben, Rather than buying battery powered speakers why not buy a good battery and an inverter or two? This leaves you able to use any inventory you already own, rather than paying premium prices for "convenience". I have found the Cen-Tech Harbor Freight inverters to be very clean, available in a number of power ranges, and really inexpensive, especially if you find the right coupon ;^). A sale notice came today with the Cen-Tech 750 watt continuous/1500 watt peak item 69660 for $39.99, plenty of power for most S.O.S. gigs. For as cheap as they are, getting a backup (which you might leave wired in your vehicle) makes sense, though none of the 3 Cen-Tech inverters ( 1K/2K & 2K/4K) I own have had any problems. If you decide on lead-acid batteries, the AGM (absorbed glass mat) deep-cycle type are worth the extra expense, no water to add, nothing to spill, available in a size to fit any package you could concieve of. You pay by the pound, going with multiple small units has some advantages, though is ultimately a bit more costly per amp hour delivered. If you want to really reduce weight and invest in something that can ultimately cost less per delivered power, Lithium Ion Iron Phosphate (LiFePO4) are a good choice. LiFePO4 require careful attention to individual cells, a BMS (Battery Management System) further drives up cost, but will prevent individual cell death, which can result in system failure. LiFePO4 are probably not worth the extra expense for the amount of use you would be using them for, but the peak power they are capable of is incredible by comparison to lead-acid. Add a 100 watt solar panel, and you can keep a well-insulated refrigerator full of food from going bad during power outages. Power was out for around 28 hours after hurricane Matthew, and 9 days after Irma, during which I increased panels to around 500 watts... Art [/QUOTE]
