Topic: power supply for V-2???

[Big Perm]

Ok, so i just picked up a V-2 and need battery supply.  what are my best options?

[coloartist]

I use a Kindkables.com dual power cable with two Walmart lithiums. This gives me a huge amount of hours, and if one battery dies on me, I stil have a backup.

are u talking about the 9v lion DVD batteries?  Will this one work with the v-2..UNIVERSAL DVD Battery, 9V 23Wh LI-ION by Lenmar?
thx

the lenmar is the same as the one in the link you just posted? also, i have read about an internal switch for 6v - 12v.  what do i do here?

if you buy a 9V battery, you leave it on 6V and the extra voltage is released as heat.

ok, very cool, now is the machine set at 6 or 12 when i get, its used, so how do i check? if the 9v powers it, its set 6 if it doesn't it's 12v?

Correct:  if the V2 is set to 12v, the 9v battery will not power it (see the manual and/or Grace website for how to change it from 12v to 6v).  If the V2 is set to 6v, the 9v will power it fine -- but the V2's low battery indicator and auto-shutoff features won't work any longer, unless you recalibrate them.  I believe Grace has the calibration instructions on their website.  At least for the V3, anyway, not positive about the V2. When I ran V3, I never bothered recalibrating because the 9v battery had its own battery meter.

Brain cramp.  See Ed's correction here:  http://taperssection.com/index.php/topic,126547.msg1680268.html#msg1680268

Edit to add:  Sorry for bouncing the thread around a couple times.  I flubbed the first move.

This is my V3, but the cable and battery are the same with a different connector on the V2.

[thekittycatt]

Bennett,

Is the power cable coming from the V3 connected to both batteries?

[Big Perm]

i was going to ask the same thing

[NOLAfishwater]

running two 9V batteries allows you to get something like 8.5 hours of run time.

[Big Perm]

how long if you use one battery at a time?

[Jhurlbs81]

When I ran my v3 as a pre-amp only I'd get at least 4.5 hours.

there is no switch for changing the voltage on the v-2.  the 4 pin xlr input is wired for both 6 and 12 volts.  if you wire the cable pin 1 neg and pin 4 pos the v-2 will run on 12 volts, if you wire the cable pin 2 neg and pin 3 pos the v-2 will run off of 6 volts.
for the 9 volt lion battery i use the 6 volt system.

Of course.  It's been too long since I ran one.  Thanks fo the correction, Ed.

[Grace Tech]

The V2 has Jumpers J21 and J22 for 6-12v selection (see page 2 of: http://www.gracedesign.com/support/v2_voltage_cal.pdf). Like on the V3, these only affect the Low Batt LED and auto shut off point. The 4 pin XLR wiring that Ed is referring to is on the battery end for Eco-Charge Batteries.  The 4 pin jack on the V2 has pins 3 and 4 (+ voltage) connected and pins 1 and 2 (- ground) connected. We recommend using pin 4 for + and pin 1 for ground.

Does anyone know the size of the connector for a V2 power cable using the portable DVD player batteries like the ones discussed in this thread?

Does anyone know the size of the connector for a V2 power cable using the portable DVD player batteries like the ones discussed in this thread?

so i think its one of these two.

http://www.mouser.com/Interconnects/DC-Power-Connectors/_/N-womu?P=1z0xbudZ1z0vlpqZ1z0x81jZ1z0x813

i was also wondering about making a cable that allows me to run two batts in parrallel. i remember someone saying that you should use a diode. but cannot seem to find that thread. anyone have any advice(other than ordering from kindcables).


found this thread, thanks NOLA

I got ya justy.....   obviously the V2 end has a 4pin XLR style and the DVD "wally world" lithium battery has a barrel style type "B" plug.  Don't know if the type "B" is a universal code name....  but that's what Radio Shack calls that size in their "Adapta-Plug" series. 

Outer Diameter:        4.0mm
Inner Diameter :        1.7mm
Radio Shack part # :   273-1705

edit to add:  If you're running an adaptaplug cable, I think this is what you want.  If you're running some other type of cable, this is still the size that you want.  Hope that helps.

Thanks! I was just looking for that info myself.

So this is the Walmart 9v lithium?

[flipp]

Label on it is different than any I have seen in the past but the specs are the same and the physical appearance is otherwise identical; however, the price has gone up $20 since the last time I saw one of those in WallyWorld. There is a thread around here somewhere about an ebay seller who has those for less than $20 shipped. I highly recommend going that route rather than waldoworld.
