This is my first time posting here on this site. I know some of you visit a few other sites that I use but for those of you who don't and have questions about the New RC3000HV I will try and answer all your questions. We have been testing these new cells since Spet. 5th. I will also answer any other battery questions.

Danny: I have a couple of questions on the HVs I hope you can answer!

1. I've noticed that these batteries seem to have a "turbo" effect. When the car is rolling and you 'punch' the throttle there seems to be about a milli-second of delay before you get the real power. I have been running SMHs since May and I do not see this effect. This characteristic is most obvious one the first charge of the day! Is there an explanation for this?

2. With my SMH, when the batteries 'dump'..... they dump real quick. With the HVs they seem to go 'soft' for a period. This does not really show up at all on the discharge curves. Is this normal?

Thanks in advance!

dtm: How was the pack matched and how are you charging it ?

What type of racing are you using it in ?

We have not noticed this with our packs.

Danny: My HVs are loose cells, I only wanted to try them out!

I run touring cars with between 8-11 turns.

Have been charging the HVs at 5A, 0.05v delta on a Protrak and Pitbull, both with the same outcome.

I noticed this when using a 11x2 Corally handwound, but other friends have noticed this with other motors. Normally run on a small technical asphalt track so any delay in the throttle is very noticeable!

Are these loose cells voltage enhanced and are they matched ?

Are the SMH's your using matched ?

One of our mod sedan racers has been using 7 amps with a .07 peak detect on the Pitbull with real good results.

Danny, would you recomend charging them as hard as this??

I have been charging the old sanyo's at 5A 0.05 cutoff. Panasonics generally 0.02V cutoff.

MattW: The RC3000H and new RC3000HV are different in construction than Panasonic cells they will run better with a higher peak detect and charge rate.

I would use a 6-7 amp charge with a .07 peak detect on a 6 cell pack. Try to get it to charge just before you run it. If it sits for awhile repeak it.

I've used as high as 10 amps with no problems.

Danny-

What do you do with the cells after they are done running? Bring them down to 5.4volts with a T35 and then tray them and then dead short them or just bring them down to 5.4volts and tray them?

Thanks

Mike Webb

It all depends on if you need max runtime or max voltage.

If your concerned with runtime I would drop them at 30 amps down to 5.40 and let them rest a few hours before you can reuse them again.

If you want them to have more voltage then you can tray and deadshort them they will pick up voltage but drop runtime.

This is what we have seen so far.

Danny / SMC ...I have a question for you ...I'm using a T35BL, I purchased 2 of the original HV's (with the old shrink wrap) when Speedworld first got them form you, just purchsed 2 more of the new ones from him today. I went to cycle all my packs (was about time anyhow) ...the new packs, no problems, my SMH's no problem but the 2 original HV's charge but when it goes to kick into the discharge mode the screen dsiplays "Voltage to Hi!" and it doesn't do the discharge part of the cycle ...any ideas? I'm gonna call competiot electronics tomorrow but figured I'd see if you had run into this ...btw these original HV's have been steadily increasing in voltage since I got them ...and I charge at 6 amps, .4 cutoff, 20 amp discharge.

Harsh Guy: I have had this problem with original Sanyo 3000H's. They seem to keep their voltage up for longer, and even with the 15second delay between charging and discharging, the voltage on a 6cell pack will stay above 9volts. If that happens, then the discharge will not kick in. Nothing to worry about. I usually just wait till the voltage comes down to 9 volts, then use the discharge function.

DANNY: I have some Original Sanyo 3000H's, and the voltage is amazing on them, 7.14 volts for a 6cell pack(1.19 per cell) full runout on a T30. But the runtime is low, is there anyway to fix this? Thanks.

OvalMan ..thanks a million! That was it I "tricked" it by setting it to peak charge but set my 2nd cutoff to zero with a 120 second delay and that seemed to do the trick to let the voltage come down enough. Damn the voltage just keeps climbing on these, with runtime staying consistent (well ok I lost 6 seconds runtime ).

HarshGuy, have you had any SMHs? If so, how do they compare?
