Just got home yesterday from 10 days at the lake to find my warranty replacement sitting on the porch. It was the warranty battery for the exchange unit from Tekkeon for the recall discussed earlier in the thread. That replacement had worked flawlessly until ~three weeks ago when I was charging my MT2496. Started out showing a full charge on the 3450. An hour later I checked and the battery had turned off but the MT was showing a partially discharged battery. Checked the charge meter on the battery and only two lights were illuminated. Charged the Tekkeon. Tried recharging the MT again, this time it fully recharged. Curious I checked the lights on the Tekkeon, showed a full charge. An hour later I tried the charge level again, back to two lights. Plugged it in for a recharge. Within two minutes it showed a full charge. This time I left it plugged in. A minute later it showed only two lights. At this point I contacted Chris. He replied with what I needed to send back with the battery for a warranty replacement. I shipped on a Wednesday, they received it on Friday and had the warranty unit out the same day. Tracking indicates it arrived at my house on Tuesday. Couldn't have been an easier process. Only "complaint" I have is that I indicated to Chris that I would be out of town and I wish shipment of the warranty unit had been delayed a week so it wouldn't have sat on a west-facing porch being baked in summer sun and triple-digit temps for a week. Since I didn't specifically ask for a delayed shipment I really can't complain about the service. I wish all manufacturers I've dealt with were as easy as dealing with Chris and Tekkeon concerning warranty (or just slightly out by a week or two) product replacement.

Tekkeon replaced my battery once while under warranty. Great company to work with. I just wish that they provided service for units that were out of warranty. Like if I send it in with a problem and they would replace my battery for me for a charge. Apparenty it's less work and less costly to just buy a new one.

I am in the final few days of deciding between the 3450i or the BG 10-14-115 to run the 680 and have been going back and forth based on experiences I've seen here and of course a 60.00 difference between B & H tekkeon price and the bg.  After the last few posts in this thread I think the extra 60.00 on the BG unit is well worth it. . .

I have both a Tekkeon 3450 and a BG 10-14-88. They both have their strengths but if you only need 12v, I think you're making the right decision going with the BG unit. If you need some other voltage or need to run two units and one can take 5v via USB then the Tekkeon is the better choice. If I had to buy batteries again I'd probably still go with one of each.

Thanks for input.  Yes I am currently mainly concerned with the 680 as I have built up a small "arsenal" of lenmar 9v I use for the v3 on festivals, but vibes will be the first full fest with the new 680 (used lithium cells for the one day I did at at mt jam, but far to expensive and obviously inefficient long term) and want to be best prepared.

Thanks again,
Bob

Bob,

I do the complete opposite of you.  I use DVD batts for my 680 and run my V3 with a Tekkeon 3450 at 6v.  It's a waste of juice using 9v on a 6v V3, IMHO.  Vibes always has  power in the taper section so bring your chargers to charge you batts during the fest.

Sorry if this re-hashes a previous question, but, when you are running the 3450R2 which automatically locks to the voltage required, would it be right to assume that it would lock to the lowest voltage necessary. My question is based on the fact that a littlebox can run on power between 5v and 12v, so I am trying to determine what kind of runtimes I could expect if I were to use it, and whether it would lock to the 5v setting.

Be very, Very, VERY careful running the Tekkeon with the 680 and do not use the automatic detection settings. Now on our 3rd DR-680, Acidjack and myself and all but confident this will fry/corrupt the unit; it must be sending too much voltage through while making the detection.

I'm hopeful it's safe to use a tekkeon on the manual 12v setting, but we're not about to fry our third unit to test and it's always worked flawlessly on 9v DVD batts.

....or do not lock the inproper voltage....I learned the hard way on a PMD-661. :(

Hey Ted, Excellent point re a waste to run 9v power on 6v device (that I had not even considered).  But my bigger concern is running 9v on the 680 based on an issue I had on 5/13 with no real explanation and I am still trying to troubleshoot to make sure I have no issues with the unit.  Although based on yours and hi and lo's experience it may not have been due to 9v power.  In any event it's time to invest in a 12v power source.  I always get a full day out of my 4 dvd's but will be sure to carry at least one charger onto the field.

I was told here to run at 7.5 so the low power light doesn't come on prematurely.

I was told here to run at 7.5 so the low power light doesn't come on prematurely.

The problem I've found with the tekkeon series related to voltage is that it seems to slightly undervolt what you're setting it to. If I say 11v, then I get 10.5 in heavy draw or 10.8 in light draw. It's why I can't run them at 10v on the 722, because I end up with 9.8 or so and 9.75 is the cut over point (or close to that) so any disruption or additional sag would cause it to constantly switch back and forth.

Pretty sure the low batt light goes on below 5.5v, at least that is when I see it go on when I forget to set the tekkeon at 6v at power up.

EDIT: From the Manual
 
LOW BATT: For the 6 Volt V3, the low battery indicator flashes if the battery voltage drops below 5.75V. For the 12 Volt V3, the low battery indicator flashes if the battery drops below 11.5V.

Were yours still under warranty? I think I'm having a similar problem. I can use one until it gets to half-full, then it shuts down. When I connect the charger, it shows half-full, and it only takes about 30 - 45 min to charge. This battery is about 2 yr old or so.

The other one I have will only turn on if I connect it to the charger. This is about 2 yr old too.

It's a shame if I can't get them fixed. I was the biggest supporter of these batteries. I have 2 that seem to be working fine, but these other two have failed for some reason, and from talking to Chris it seems that they are out of warranty.
