Wow this thing rocks for us oval guys it will hold 2 packs at once heres the link for it www.teamtekin.com :thumbsup:

It does sound slick. I am not one that deadshorts much, so this tray would be nice. It is not a new idea though. The promatch smart trays did the same thing. It took the cells down to .5 and held them there. A good idea though.

Absolutly Your Right Tekin Is Just Trying To Put New Products Out There For Us

Now the big questions will be:
Does this work with 3700' and/or 3800's?
Is this tray more for Stock/19T packs or Mod packs?
Will it maintain or hurt runtime?
Will it help or hurt voltage/IR's ??

3700 S 3800 Will Not Hurt Anything

This tray is the real deal. It is all solid state components, not just resistors. There has been a lot of R&D gone into making this tray the first of its kind with being non polarized and solid state with LED indicators. It keeps the packs consistent from the first run to the tenth and so on. It is the real deal for the racer who isnt deadshorting.

The Tekin discharger tray looks very nice..as does the Novak tray.
There great for the GP3300 cells.

I can't decide on that or the Zero V tray which I have heard great for the new IB3800 cells and the older GP3300.! :thumbsup:

I will have some for sale on HobbyShopper next week if anyone is interested. Not sure of the price until I receive my shipment.

Are these are better than the Novak Smart tray? Anyone know?

Thanks

Does anyone have experience using the Tekin BC112C to charge NiMh cells? I have one of the first ones from when they first appeared. I usually dead short my packs (3300's) then use CS "cold start mode" (similar to long lockout on a CE turbothiry) This seems to be working fine, but am wondering about other options.

I USE THE CHARGERS what do you want to know?

If it ain't broke, why fix it? :) Honestly from the sounds of things you are doing things just like you should. I'm guessing you probably have an E26 or E28 software charger if it's one of the earlier versions? They will tell you, you need the latest software versions to "safely" charge the NiMH packs but we had good luck charging everything from AAs to 3300s with the earlier software. I now have 2 112Cs with the updated software (and a 112A without) and can't tell a difference in the charge between now and the earlier version. :rolleyes: Just so you know...........I use CS on each charge from fully discharged with a 5 or 6 amp charge (depending on 4 or 6 cell charging) and P2 for a repeak.

I normally use the CS mode on my GP3300. With the new IB cells I would guess that would be too much drop and mode 1 would be better to use.

Dunno Hank, I read on Tekins site (in the forums) that the CS mode has the 10 min lockout but after that time it has the same dropback of the P0 mode. Of course with an older charger, they don't have the P0 mode. :)

My instructions say P0 mode has .03 drop, P1 has .04 and P2 has .06-.08. CS mode has the drop adjusted by the charger depending on the charge slope. I know to get my cells to 130 deg. I have to use the P2 mode as P1 will only get them to about 120. CS easily gets them to 130 deg.

They can say what they want but I have different results in actual use.

Hmmm.........guess you have found "otherwise" to what is posted over there. :lol: Good info. Always good to get more than one opinion. I'm guessing they've updated the instructions as I don't recall that information in mine? Of course mine are old but now I'm curious and will have to look.............

If you read http://www.hobbytalk.com/bbs1/showpost.php?p=1233465&postcount=60 you'll see someone else has the same opinion ;)

The tray is designed to take each cell individually down to .05 volts and keep the cell at that poin. If the cell voltage creeps back up the the circuit turns on and pulls it back down

Many trays can effect battery runtime and voltage in a negative fashion, just because it discharges your pack does not mean it does it correctly. just like charging your pack , discharging it incorrectly can have negative effects,
An extreme amount of R&D went into this tray to find the most suitable way to maintain your packs, the result is a tray that performs well under all conditions and provides a stable discharge atmosphere for your pack .

:wave: This tray is much more advanced thaan the old promatch tray, try it for yourself

:wave: This tray is much more advanced thaan the old promatch tray, try it for yourself

I still have 2 of the Pro-Match trays. From what I can see they do the same thing you just described? Am I missing something? :confused:

Well first of all the new TEKIN tray is non polarized, and the discharge rate is higher. but most importantly is the way the circuit works, you are correct in saying that both trays generically achieve the same end results but it is the method that the tekin trays circuitry performs this task that seperates it from everything else. I will try to elaborate later on how the tray works.(There is a reason that the Tekin tray has 3 times the electronic components on it, and an industry first integrated heater circuit)

Also dont forget a true LED per cell indication as to the status of the pack and each cell individually. :wave:

Price ?

Tower Will Have Them For 49.99 Retail Is 69.99

50 bucks

Paul,
I have the older version software that has P P1 P2, and I think P3.
And then the Modes are P1 P2 CS What re the voltage cutoffs for my software?
Rick <><

Iam unsure of the exact cut off pionts used on the older charger, your best bet is to call Tekin directly and ask their tech guys for some info :thumbsup:

Paul I'm not trying to start an argument with you or anything I'm just saying that in your original post it basically stated that the Battery Doctor was supposedly FAR superior to the Smart Tray that was made by Pro-Match. From what I can see it does the same thing so what makes it so superior? Non-polarized? Whats the big deal with that, so you can put the pack on any way you want. Discharge rate is higher? I'm looking to equalize my packs not discharge them so it doesn't make any difference to me if it discharges at 2 amps or 50. I will give you the LED per cell is a nice feature and to tell you the truth when it comes down to it if I need another tray I'll probably pick up one of the Tekins since I like the chargers so much. The only thing I would have liked to see on it is thumb screws to secure the battery in place.

Rickthumb screws are nice but they also have some downsides, mute point , but As I mentioned earlier the tray uses some technology that I cant exactly discuss publicly, Yes you are correct in stating that both trays acheive the same results, and all iam saying is that the Tekin tray acheives the same results using some technology that has never before been used in discharge trays, and this process enhances the packs performance,
Iam not saying that the promatch trays do not work, just that the Tekin tray performs better. (or acheives the same end result using a better process)
I say same end result being that it discharges/equalizes the cells down to .05 volts.
I have owned every discharge tray ever made and have been doing some testing most trays acheive the same end result- They discharge the cells as down to a certain point and stop, But the way that you do this can have different effects on the packs performance and longevity.

dont mean to drag this out but just look at one and you will begin to see that it has some things going on that are quite different :thumbsup:

Sorry Previous Post Posted By Paul Schwanbeck

We now have a few of the Battery Doctor trays in stock at Hobbyshopper (http://www.hobbyshopper.com/shop/). $48.99 plus shipping.

There is a closeup view of the circuity so you can see what it uses to discharge (as if we know what the ICs do anyways ;) )

Paul.......one way or another I'll probably pick one up and give it a try. I've had these other trays to long anyway. :)

:freak: sounds good

I really like that it has 8 slots.. i would assume you can do 2 4 cell packs at the same time?? Nice its like getting two trays for the price of one..

Yes You Are Correct 2 At A Time!

Another round of battery trays are on their way to the distributors, and people are starting to take notice, Tekin is back in the game full force.
If you have not seen some of tekins new products you must check it out! The new G11 speedo is also out!

ive seen the g11 and it looks really good. im just curious what makes it so good? im lookin to get a new speedo soon. right now i run LRP quantom 2. sell me on the tekins!

joe ivo

Who has the G-11's?

my friend runs for tekin and has them. im debating on buyin one when they come out. what are the pros for this speedo. :)

joe ivo

This is the post I was referring to.What hobbyshop has them?

Hey paul. when do i get my test model.. Team wisconsin right????LOL..

Hank,

Are you going to be carrying the G-11's?

I had been thinking about it I'm not sure there is the demand for it. The G10 was a slow mover but maybe I can get a few with my next order this week.

[Update] - Just made an order I should be getting some in late next week.

The Problem With The Novak Tray Is That They Missed One Important Thing ,to Hold All The Cells At The Cutoff Voltage Preset By The User.
The First Cell Done Rebounds And So On And So On , I'm Not Sure Why Their Engineers Don't Get It And Fix The Problem.
You Have To Hit The Start Button 6-10 Times For Better Equalization.

The Tekin Tray May Be Based On An Older Theory , But Still A Very Good One That Many Major Matchers Like "pro-match " Still Endorce.

Leave Your Packs On The Tekin For 30 Minutes And Your Cells Are All Equalized To .70 Per Cell , You Don't Need To Go To Zero To Equalize.
Besides The New 3800's Loosing Big Time Run Time When Hitting The 0.0 Mark This Subject Is Way Over Thought By Many Racers.

Buy The Tekin , Use It The Night Before You Race And Have Fun.
Yes , A Slight Voltage Gain Will Be Seen Even Going To .70 Volt.
Runtime Will Be Lost Everytime You Cycle A Battery No Matter How You Treat It. Worse Now With Nimh Than The Old Nicads.

We now have a few G11 Pro's in stock. You can order them at www.hobbyshopper.com

News flash, Pro Match now has the tekin trays in stock and thay say it is the only tray they reccomend. Now that is saying alot!

I have been using the Battery doctor for the last 3 weeks and I am loving it. Seems to be really helping my packs.

Well now I'm really confused. 2 of the most respected matchers recommending different traying methods. I generally trust what pro-match says, but they are the ONLY MAJOR matcher recommending the use of extendede equalizing times and diode cutoff. And lets face it, they do have a something to gain by recommending a tray they sell.
I still have the older pro-match trays, and the older integy trays. How is this tray different? The components are different, sure, different way to do the same thing, probably cheaper. I really want to get to the bottom of this equalizing thing. I have used the Integy 0-30 method of quickly discharging\equalizing just before charge with excellent results. Does ANYONE have any data/numbers to back up the claims of this new Tekin tray? It seems to be common knowledge with the 3800's NOT to keep on the trays for an extended period for fear of runtime loss. Does Tekin/Pro-match know something the other matchers dont? This is not by any means meant to be a dig, if there is a better way I'd just like to know and take advantage of it. If anyone could cycle a 3800 pack that was used on the Tekin tray for at least 10 runs I think we would have the answer. Who's feeding us Bull?

Mayhem,

From what I understand,cause I've ask this same question myself,it seems that it's another one of those "personal preference" things.Some data to back up one or the other would be nice,I think Steve from TQ did give some #'s ? and he came to the conclusion that it made no difference performance wise.I'm sticking with the 0-30 cause of the time factor and I'm getting really good results on the track with it.Also, I'm going on the premise that batteries need to be "trained" and 30 amps is a whole lot closer to what's happening during a race than 2 amps,also there's the heat factor and the 0-30 gets the packs a little warm before the charge which is good for these 3800's. .02

I agree with the personal preference theory and if someone did a test with 10 packs on 6 different discharger / equalizers the results would be interesting , but with battery technology changing as fast as it is , its a constant battle for any matcher to reccomend a specific technique that works across the board. How many Top matchers have changed their mind many times since 3800 came out.
Bottom line --Pro -Match who has been around a long time has a great product "Tekin Battery Doctor " for the average / above av. racer, And you won't kill any cells using it .
If you think Jeff only reccomends this because he sells it , then you don't know much about his company . He's so swamped with battery orders that they no way had time to come up with a new tray , but fortuately Tekin did.

AGAIN , IF YOU ASK 10 RACERS ALL YOU'LL GET IS 10 DIFF ANSWERS WITH HALF OF THEM ONLY THEORY , NOT DOCUMENTED,AND MOST WILL HAVE A DIFFERENT ONE NEXT WEEK.

THE TEKIN IS DEFFINITLY ONE OF THE BEST BANG FOR YOUR BUCK TRAYS

YEP! this is true
