I just started cycling my SPEC packs from last year, they have sat shorted all summer(off road during summer, now back to carpet). I was pretty amazed at my findings. You guys may squawk at my routine, but it has worked well enough for me to win my point series....

Charge at 6amps, punch with torpedo, cool, discharge at 15amps(dont think spec motors pull much more than this??), single light until next cycle(whenever i get to racing again). Race day, charge at 7, punch with torpedo, AND RUN BABY!!!

Now some info...

Last year, i taped the back of the packs and wrote average, MAH, and ir on them. One pack i just recently did basically astonished me.

Last year:
Av: 6.229
MAH: 1498
IR:86

This year:
Av: 6.537
MAH:1554
IR:69

I figured these packs would be trash because i basically left them dead shoerted for about 7 months, but as you can see by the numbers, it actually got better!!! I will be running them OCT30th and will see if the numbers aren't inflated or wrong, and how well they actually perform..

Maybe the integy chargers #'s look diffrent but those would be terrible #'s on a GFX.I love the graphing feature on the GFX it tells the whole story,and with the packs being so close sometimes you need to be able to sort with the graph throughout the whole run.

It must be nice, but i dont have $400 to drop on a charger at the moment. I dont know how different, or what the difference is in the way i charge and cycle compared to most. All i can say, is they work for me. The graph feature does look pretty neat to me, you can actually tell what the power curve is, thats nice. I wonder if i can set my graphing digital multimeter up long enough to actually graph a pack discharge.....hmmmmmmm gonna try.

Oh yeah, what kinda numbers do you get out of your spec packs?? And what do you charge and discharge at??

I've been experimenting over the past two weeks,so far have found that 8 amp charge and 20 amp discharge with at least a .04 or higher peak detect seems to give the best results,using the graph;tells me that this is giving the best overall voltage curve for 4 mins.The only question I have is at these rates how long are the packs going to last?You've got to deadshort for sure,as most people have been telling me,so far my best pack is 6.66 with a 49 IR,and 300 secs of runtime,the torpedo is to account for the low IR,I already knew it worked from past experience,just wish they were of a higher quality.Now if I could just find some HP(hint hint Steve or Brooks) I would be okay LOL

Hey, just ran my car last night. Well, i guess im doing something right, it is damn fast. Whether the numbers on my Integy wind up being different from CE i dont know. But i do know, most couldn't hold me last night.

We'll see when the season starts, butif it looks like it did last night, i will be hard to catch again this year......

i charge mine at 6amps and discharge at 10amps

i have never lost except when i did not have a battery charged

can anyone tell me where I can find any six cell packs?

I own a pair that I use in our T-Spec racing. I have ran the car for six months and have used two different chargers one only went up to 5 amps. I have a Nimble motor sport dual digital charger that I use now, and it can charge up to two batteries at 6 amps. (which is great if my son is racing Spec too!)I have noticed a difference in punch using the 6 amp charge method and discharge at 25 amps. Seems to work as I have one of the fastest T-Specs at my track :thumbsup: We are currently in the process of a 6 month point series and pretty much everyone charges at the same rate with a few exceptions that do not have a charger that will charge that high.

Hill Jack, give Marshall's Hilltop Hobbies a call at 570-729-7458. They have plenty of spec packs in stock. The day you call they will be shipped that afternoon. They are in Honesdale,PA. They also have them at a great price............WAYNE

i have spec packs for sale 16.50 a pack NEW IN BAG also spec motors and replacement arms also dyno tuned spec motors call and ask for john @SPEEDWAY MOTORSPORTS 404-245-3450

I have some 4 cell packs, can charge and discharge them with an Intellipeak but am afraid that 10A discharge option wouldn't be enough.

Besides using a second charger/discharger or light bulbs, is there any convenient solution/device for 4 cells, wether for racing or bashing around? Have not much time to build anything especially if other guys would join me.
