Topic: Marantz 660 external 5v.... ???

[NOLAfishwater]

Was wondering if you have found a good external battery pack for the PMD 660. Here are a couple of 5V rechargeable Lithium Ion battery packs that I found online.

Quick Charge- Around 90 Minutes,  $99, doesn't say how many Watt hours of output is has, however, this unit is on back order. I am going to probably buy the one below or there is a 6V model as well. I guess if Doug Oade has said that it will handle a 6V input then, maybe I will get the 6V

$99

Key Features:
High capacity. Most Digital Cameras/Video Camcorder's standard batteries only have 5Wh~10Wh capacity. This battery has 44Wh (Watt-Hour) capacity. For reference, an AA battery has about 2.7Wh capacity (1.8Ah at 1.5V). This may help calculating your expected run time.


Ultra light weight design.
Compatible with
Devices which require 5V, 8.4V or 11V power supply, such as network routers, BiX Pocketsize USB or Firewire hard drives, BiX Slim USB or Firewire Optical Drives.

6v powers it fine, and is available MUCH cheaper or via DIY than a hundred clams

i have used a 6v sla successfuly.  no trouble there.
but...why ?
7 hours w/AA batteries.  who needs to cart lead around?

Do you have directions on how to build this pack that you have?  how much did it cost to build? how many Watt Hours does it produce?

depnds on how much juice you need.
the easy way....pick a 6v RC pack and charger.  that should do it fine.
or a 4 cell sled of any size.

Works fine for my 660 & my R4. Little pricey but..........

excellent battery.  I have one too.

however, for small and cheap and effective...
1. good NiMH cells will run it better than 4 hours
2. Energizer e2 lithiums will run it for close to 6 hours
3. this would run it for a while too: http://tinyurl.com/38tz35
    wired in parallel, these would run it for years probably.  All for cheap cheap.

How long does it power your 660?  I think  I did my calculation right on that power runner and it puts out 36Watt Hours. 5Vx7.2Ah=36Watt Hours. I think I am going with the one I posted above, b/c for $5 more you get 44 Watt Hours and it charges in half the time. It says 3-4 hours for max charging and it does not have to be discharged. I have been running duracell 2600 mA rechargeables with a LaCrosse charger and that seems to work well, but since I am planning on going to festivals this summer, I wanted to have a power cell that can run almost all day. Can't wait to get it in.
