Now This is a Battery
« on: December 29, 2010, 11:15:37 AM »
This an electrovaya PowerPad 330 rated at 330 Whr - It's equivilant to over 6 Tekkeon's (shown with a Tekkeon to give an idea of size)


It has 2 USB outputs and 1 higher voltage output (rated at 19-24V depending on how the connector is jumpered)


Weighs about the same as a 7.2AH 12V SLA (which is approx equiv to 86 Wh)


Picked it up on ebay for $75.


Now I just need to build a power distro box (with various high efficiency DC-DC converters) and I will be able to run 4 channel at a festie w/o recharge.

I like the way that you're leaning - I'm looking at the possibility at running a pair of these in the field in the future and this battery may be the answer to my 4-channel festie needs as well.

they still make those?  didn't realize....

I used to run one 8 or 9 years ago.  A few of them overheated on people and actually burst into flames if I remember correctly.

Which model did you run?


I have an electrovaya PP  160 that I have used for 8 years and never had any issues.  I make sure I keep the current pull below 1.5A when I use it though.

Electrovaya still sells batteries but mainly to OEMs for use in there devices (such as cars)


The only have 2 models that they still sell to the general public the Power Pad 130 and 95.


I never have heard of anyone's EV battery bursting into flames but I did know of alot of people having problems with them.  I always thought it was because they where running to much gear off of them or laptops (i.e. pulling alot of current - shortening the life of the batteries).


Like I said before I still have my Power Pad 160 and have never had any issues with it - I would run my Tube PS's and a DA-P1 off a duel VR box I built and then an ADK off a seperate 12V SLA.  Probably ran it like this for 30-40 shows without issue.

Lithium-based battery technology is fairly new technology.  I read that the lithium battery is the main reason for the world-wide cell phone boom. 

The battery university says that the problem with the early Lithium battery technology was that the early formulations were unstable and flammable.  I can't comment on any of these batteries, but you'd like to think that the technology has advanced such that Lithium battery chemistries are stable and safe.

Bump w/ pics of my power distro box ->

16 - 24V input (wired to run the battery at 20V) Provides 4 4pin XLR's, all with pins 1 and 2 at 0V, pin 3 at 6.5v, and pin 4 at 12v (using 95-97% effecient DC-DC converters - max of 2A per rail)

I also have a PowerPad 135 which is much smaller (135Wh) and works with same setup.

Hrm...  :hmmm:

That's a really slick setup. What's the size on the smaller power pad?

The orange is slick. Powder coated?

The 135 is the size of a mouse pad but about 2x the thickness.   The both batteries have 2 USB power ports as well so I can run 4 6.5/12v devices and 2 5v devices all at once.


It is powder coated - Hammond sells per powder coated cast aluminum boxes in 5-6 different colors.
