Default Discharging

Hi Guys

I have a Duratrax ice charger but it only discharges at 10 amp

Would you guys recommend this 20amp unit by Integy?

http://integy.automated-shops.com/cg...11105399804.a2

Also after discharging would you recommend putting it on a 20amp tray?

http://integy.automated-shops.com/cg...37105100946.71

Or will the tray be enough?

Any Help would be great

Thanks

What do you want to achieve?

If you race your packs until they drop, 10 amp is good enough to take out the last juice. eventually, you can use a 20 amp tray alone, no need for both 20 amps discharge AND 20 amp tray.

If you dont want to take them down to zero volt and you dont race the car till it drop, it might be another story.

So, what do you want, runtime or punch? Long lifetime, or maximum performance regardless of battery life?

Hi Cole

I will be racing in stock so i want punch but at the same time want to get the best out of my batts but not kill them in doing so.

Any suggestions?

Thanks

Well, we're in the same boat for what we want, I do also race in stock, and want to keep a reasonably budget, thus I like to have a reasonably battery life time.

So far, I've been discharging mainly in the car, since most of the time I'm practising, and race the batts till they drop. In this situation, there's little (maybe no) need for an 20 amp discharger over a 10 amp ditto.

If you go a lot to regular races, where you only race for 5 minutes, there might be a need for 20 amps discharging.

I think the big question is: shold it be an equalizer with auto cut off (which usually is low amp) or shold the cells be discharged down to zero volt?

In the last case, it's a straight forward: Get a high amp/zero volt tray, to complement your Ice.

Personally, I've been using a 1 amp, 0,8 volt auto cut off equalizer so far. To be on the safe side. And with good results. Both on the track and on the discharger. After approx. 30 runs, I still get ery good data (almost as good, as when the pack was new) But I'm more and more considering getting a 20 amp tray and go down to zero volt for even lower IR and higher voltage. It seems like the GP3300 wont be hurt by doing this. But I dont got personal experience.

Someone else please chime in

I suggest this instead: Apex 20 A tray

Nice price, and much easier to mount batts, than with these small screws.

Integy have a similar 30 amp model and with two fans for approx. 70$ - and it's made by Apex

Wouldnt 30amp be an overkill for stock racing?

Thanks for the link looks good

At my opinion yes. I think it's too stressing for the cells. The more heat, the shorter the cell life. But again, I havent tried it myself
