Just the info I was looking for. Thanks. Have you tried charging at higher amps for 1st or 2nd? Also, what is your delay between 2nd and 3rd? Thanks for the info. One more question......what is the difference between the static and impulse charge and the linear charge. Why would you choose one over the other?

And (last question) should I use the same profile for stock and 19T and mod? If not how would you adjust it? Thanks.

<1st Question>
Yes, I tried higher amp. in 1st & 2nd stage beofre.
In fact, I recommend you to use high amp in 2nd stage. 1st stage should be used for lower amp, because battery is still sleeping at the beginning. If you put a bunch of power from the beginning, battery may be surprised...(may be Damaged)
Therefore, you can try this also.

1st 500 mA 3.5A(static)
2nd 3500 mA 6 or 7 A (static)
3rd 5000 mA 4.5A
delta peak 24mV / Temp 45 degree

<2nd Question>
You don't have to use delay in this case. Because I put delay mode in the profile. Please take a look 2nd stage carefully.
Why I can put 20 mA at 0.2A???
This is because I want to make battery cooler.
It takes about 10 minutes delay if you use my setting for 2nd
stage.

If you use ; 2nd 3510mA 0.2A setting, it takes abnout 5min.
cool off time.


<3rd Question>
What is the differences btw static, impulse, and linear...
Maybe, you confuse these.
At first, we can divide linear charger and multi stage charger.
linear charger is that we cannot change the charge setting while
charging, like LRP Competition or Reedy charger stuffs.
Since you cannot change the charge curve, we call it linear charger.

Multi stage charger has a function to be divided in the charg
setting in charging process, like Record Breaker, Front Line2,
Cell Master, Pit Bull X3.

Now, the differences btw static and impulse is ;
impulse mode let battery stimulate by using high current within
a few micro sec. static is none.

<4th question>
You can use the same profile even you run whatever you can run.

Hope this is all answer to your question.

Thanks for the info again. I 'll try both profiles and see which one I like better. You know... I didn't recognize your name at first, Eiji? But I think you were the one I met when I was at socal for a couple of months. I guess that's how I met Hiro as well. (Actually....I saw this guy flying buy me on the track and had to find out how he was doing it so I think that's how I started talking to Hiro!!!). And I remember I didn't see you for a while and found out that you had flown back to Japan for a few weeks. I appreciate the info. Hopefully I get to try it this weekend. Unfortunately we are supposed to get snow so I'm hoping that I can at least make it to the track. Then if I get snowed in....oh well. I guess that means more practice for me because if I can't leave then the Track owner can't leave.

One more thing. When you deadshort your cells, are you just leaving it on the tray, or are you discharging all the way down to 0.0 volts then solder a wire across the terminals. If you use a tray, which one do you recommend. Thanks again,

Jeff

the much more racing zero-v worked pretty good for me. stackable too. ill probably start using them again since i have my record breaker chargers now.

eiji! thanks for the tips. now i can keep up with you.

Jeff,

I don't know who you are. I knew you are Hiro's friend.
Maybe, I met you before at SoCal.

Talking about dead short, just stay it on the tray.
Since the word"dead short" becomes very popular, many people
has many different understanding about dead short.
What you wrote here is that both method are "dead short".
However, there is "good" dead short and "bad" dead short.
Good dead short is just to stay battery on the tray.
This means that battery cell discharge individually.

Bad dead short is hook up positive to negative after discharging
battery in deep. If you hook up positive to negative, 6 cell is
connected directly. not individually! Need to discharge individually.
This is very important.

The reason is that each cell has different nature, like each people has different nature. So, even you buy good matched battery,
actual cell looks like "matched", but not perfectly "matched".
They are just selected to be similar.
It is impossible to make same nature.

So, I don't want to spend battery so much, like other people
does. What we have to do before charging is to adjust cell's
nature equally. (Cannot make it equally, but as possible as we can).

In addition, there are bunch of discharge board in the market.
Most of them has 0.9V cut function. This is not so good for
record breaker or front line.( better! but not best!)
Trinity, Much more or integy make individual dischargers, so
use one of these.

I make own discharge board. Some SoCal people, like Hiro, Taka,
use this. This is the same concept of Trinity Realtime 2.
When I start using this, many people are curious about it. But some has been doubt. Now, at SoCal, many people start using
such kind of individual discharge board. So I guess people
start aware of the advantage gradually.

What I expain here is based upon my experience. So please
read tips as one of personal opinion.

Hey! Chris,

Now you got it! I will give you more info. this Sat.

As far as run time goes, Eiji's method does seem to work. Last night we both charged a pack and went out together. I ran out of juice probably a full minute or two before Eiji dumped. it's quite amazing.

Either that or I was overgeared!

jeff your always overgeared! just kidding. when you leaving for asia again?

Thanks again for the info Eiji. What I have been doing as far as maintenance when using my GFX to charge is after a race I discharge the pack to 5.4volts. Then I put it away until next week. Before I charge I put it on the Rayspeed discharger and after it's done I immediately begin charging.

Now it seems as I will be using the Frontline2 charger as my primary charger. I guess my routine will have to change now. So how do I get my hands on one of your dischargers.

Hey Chris I leave tonight. Email me if you need something.

Joking aside, I doubt I was over geared--I was running a Epic stock geared at 7.97.

Jeff, that's how I keep my battery too, but Eiji's method seems to yield a lot more run time.

Jeff,

You are most welcome
I modify integy discharger.
It is like much more discharger & nothing special.
If you are interested to see it, I will send you some pics.
please provide your private e-mail address to me.

Jeff,

Have a safe trip back to Asia.
Run together next time.

Eiji: With regards to dischargers. I have a Trinity realtime2 discharger. I took a voltage reading of my pack and it is at 0.0 volts. Is it okay to leave it in there? With nothing limiting the discharge don't you risk damaging the cell? The reason I ask is because my friends NOVAk Smart Tray has a dead short function. I noticed that when I used the dead short function on the Smart Tray, the cellls voltage does not go to 0.0volts. Instead the lights flash every few seconds and the voltage is varies anywhere from .39 volts all the way up to .70 volts. Which leads me to believe that with the Smart Tray, the deadshort function will take it very low but not to "0" volts. What is your opion on this?

Jeff

so you live in CA? kewl i go to SOCAL alot.....not lately though...been busy...maybe ill see you sometime. yeh i drive offroad alot...=] im da asian kid wit da white xxx buggy hahaha planning to get a onraod tc3 and sell my buggy..offroad got boring haha..wat car do u have
