I am so excited that I've found this website.  I was really bummed that stereo2go ended. 

 

I'm hoping you guys can help me figure out one question.  I have used the search button to look for an answer to this question but has so much info its hard to decipher. What type of battery pack is everyone using to power your boomboxes while you are out with them? 

 

I'm not going to splurge for D Cells every time I want to use my boxes.  Are there lithium D Cell rechargeable batteries?  I don't really like the standard rechargeables.  Do you use external packs? Mr. Fusion?  What setup do you use?  Please advise. 

 

Current boxes are JVC RC M70, PC5, and PC11.  I think the M70 and PC5 are 15v and the PC11 is 12v.  Correct me if I'm wrong.

Stereo2Go shut down? Damn, I didn't even know. Welcome to Boomboxery though. Whenever I bring my boomboxes outside, I just use regular D batteries, which is probably an economically unwise decision on my part.

Welcome aboard, BB.  First thing... S2G did not end.  They moved to a new address when they left the old host.  You can find them at:

Here are a few threads on the topic of batteries that might answer some of your questions:

I have found that battery life in the JVC M70 and the Sharp GF-777 is pretty good - of course, I'm not running them at full volume either.

 

When looking for proper batteries, you want something with a high mAh (milliamp hour) rating.

Outstanding information here guys, thank you so much. 

 

I did find one thread that showed an external Li-Polymer battery cell source plugged into the DC port.  I see some that are 9v/12v/16v.  If my RM-70 is 15v would it be safe to run it at 16v or just stay at 12v?

Slightly higher voltage (1V) is okay for DC.  Batteries generally lose voltage as they discharge, so you would start heading to 15V almost immediately, but not necessarily quickly.  Also, make sure the battery cannot be overcharged to something crazy like 30V.
