Battery advice please
« on: July 29, 2017, 12:32:26 AM »
Been in and out of the scene over the past few years. Went to tape a show last week and one of my "Wally world" DVDs batteries shorted out and won't charge now. Planning on just buying into a new battery solution and looking for advice please.

Rig is:
R44
V2(6v)
Mini me (6v)

My current setup is a custom cable assembly that on one end splits to all 3 pieces of my rig with appropriate power connectors. Then there is a 4pin xlr that joins to the other side of the cable. The other end splits into three plugs for the Wally world batteries wired in parallel. This allows me to either run two or three Wally world batteries depending on the length of show to power everything. I also designed it this way so that batteries are hot swappable.

Looking for a current battery that would power this rig for 4/5 hours.

Thanks and advance for everyone's help!!

Steve

You are aware that Lithium Ion wally world batteries have been refurbished with fresh 16850 cells...and most likely you can purchase cells with even more capacity than were installed originally.

Short of that are you locked into 9v batteries for your current setup? There are some nice inexpensive 12v batteries out there...Talentcell has both 12v and 9v outputs.

Just copied the same link. I run a sililiar set up and can run sd 302, mini-me, and r-44 for at least 5 or 6 hours on one of these. I usually bring two and run the 302 by itself. Pretty much could run 12 plus hours like that.

Thanks so much for the reply!  honestly the whole lithium battery exploding thing freaks me out.  is there someone on this board who would/could refresh my batteries for me?

I remember reading that the tekkon batteries were very popular but then saw that Dustin's exploded and almost burnt down his house!

Would love to move to a larger single battery like the Tekkon or the above amazon link :)

With my gear I could totally run 12v,,, is this generally considered a safe battery?

Does that linked battery really have a surface mount rocker power switch?  has it ever been accidentally pressed in a bag during a show???

These could work, but you would probably need a couple!

I'm currently using a rechargeable powerbank for my 744T, which I am happy with.  I use the 12V setting and can run a festival on a single charge. Mine is a 32000mAh variable voltage.
Normal: Nakamichi CM-700's >> SD 744T (or) Sony PCM-M10
Stealth: CA-14c >> CA 9200 >> Edirol R-09HR
Ultra stealth: AudioReality >> AudioReality battery box >> Edirol R-09HR
Simple & Sweet!
