Hi Danny. Is the Powers cell all but dead in high level racing. Are you guys still matching and racing with these cells?

Default 3000HV

Danny: After a hard cycle, how long should it be rested before you can cycle them again?

I see you charge your HV 3000's at 8amps, are you running stock or mod. I also read that you can charge them at up to 10 amps as long as you have a fan on them of course, is this really that big of an advantage.

veecee: We have stoped matching Powers because of the differences in batches. Some batches were good and others weren't. Now that Sanyo has improved there NiMH cell we feel it's the best way to go.

Hobbyguy: Do you mean on the track or the machines ? We have used packs up to 4 times a day with rest periods of a few hours. Cycling on the machines should only be done once in awhile. The HV's have great shelf life.

CRASH: We mostly use 8 amps in stock. In mod it's 5 or 6 amps. Some have noticed that 10 amps isn't really faster than 8 so I don't think 10 is needed. Never put on a fan on a pack while it's charging. This will not let the pack perform at it's maximum potential. The HV's need to be warm/hot to perform well.

Do we need to use a fan on stock metals? What do you recommend charging them at for stock.

Default For Danny

Danny: I mean hard cycle on the machine (constant discharge)
How long do I rest the pack? I heard ppl say 2 days. Is that right?
Also, do I charge my Powers the same way you charge the 3000HV? To increase vlotage om the Powers, you mentioned to dead-short them. For how long to dead-short? And before charging them again, how long to remove the short for it to recover?

Thanks again

Hobbyguy: I wouldn't cycle them more than once every couple of weeks. There is no reason to cycle them all the time. In my tests I have cycled them 3 times in one day and I have also cycled them everyday. This was doen just to see how they react.

I would charge the Powers with a .04 peak detect using 5 or 6 amps. You can keep the pack deadshorted until you plan on charging it. Just make sure that the pack doesn't false peak. To keep this from happening I use the lockout on my T-35.

Danny, I used to zap my NiCd's and rematch them once during the winter season, do you recomend zapping the HV's?

Danny,
Was wondering if you could shed a little light on something.
Have you noticed that the more you cycle (On a TB-4 6/30/.02)) new cells the worst they get. Numbers begin to vary from cycle to cycle. (Bewteen each cycle a one day rest is given to the cells.)
All most seems that you need to cycle the cells twice then go get final numbers to match by???
Thanks in advance and thanks for the good info up here.

ottoman: Yes I would reccomend rematching your HV's once per season.

RCENG: It's normal for new cells to change the first couple of cycles. This is why we cycle the cells more than once before the final match.

Danny thanks for the info.
Another quick question for you ???
I was at my local hobby shop the other day and looks like the HV's have better runtime know. Does the newer batchs of cells have better runtime (363's etc.) ?
Since I am typing......Concerning my previous post.
I cycled some cells thru 4 times and got numbers each time. The numbers were farily close from cycle to cycle. I then ran the cells thru at 25 amps to get some numbers. After that I went and ran them back thru at 30 and the numbers moved. I even ran the cells thru a 2nd time at 30 and they still were in a different place. Their was one day rest time bewteen cycles. Do you think this is normal ??? or have any info?
Thanks a bunch.

Cycling the cells at 30 amps will give vastly different numbers than at 20.
