RCENG: The date codes fluctuate a bit but the runtime has been fairly consistant. The first date code was the best runtime wise. Since then they have been similar.

I suggest you match or cycle your cells at 30 amps. This weeds out the cells allot better. you shouldn't try to cycle the cells to often they get hotter on the TM-4's than they would as a pack. Plus the HV's are very tempermental to temperature fluctuations and they hardly ever give the same exact numbers from cycle to cycle. You must also take into account that the current matching equipement reads to the .001 of a volt which isn't very much voltage difference.

Danny : I just got some HV cells. They performed flawlessly but I have a question, how should I store these cells? Partial charge or dead empty, or send them down to 5.40 per pack? My RC3000 packs juzt died on me so I am pretty much scared to mess up on the HV, batteries cost too much ard here : P
TIA : )

I just got to do my first real test with my new HV cells. They seemed to give my Fantom stock motor just as much punch as my old 2400 cells do. I must say I am quite happy with them thus far. Cant wait till racing season gets rolling so I can give them a good test.

Nightkidz: After a run discharge them down to 5.4 and then put them on a tray to keep maximum power. If maximum runtime is wanted leave them alone after you discharge them to 5.4.

Hello Danny! do you really have to discharge them on a tray for maximum power? doesnt this increase the internal res? thus decreasing the power? thanks!

Default trickle charging

Danny: i normally peak my packs when the heat before me finishes. after all the scrutineering and transponder switching, it takes 5-10 minutes before my heat starts. this means my packs have rested for 7-8 minutes already (assuming 120-180 sec re-peak). question is, can i use the trickle charging option in my Pitbull to keep voltage up just before lining up on the grid? thanks.

Can you run Sanyo Hv`s more than once in a day ??

I can with my Panasonic`s Stk metals....
They seem to perform with more punch after the first charge...

Can I expect the Sanyo`s to do the same?

Cherry, yep. I run my HV's twice, and they seem to be better on the second run as with my SMH.

MOTO: Traying doesn't increase IR.

Here is a pack that wasn't trayed and then I trayed it.

before: 353 - 6.86 - 24.4 Actual IR

After : 346 - 6.87 - 23.4


purplepro3: Last time we tested trickle charging was many years ago and we concluded that it didn't give as much power as a good repeak. So I suggest you do a repeak.

Danny: thanks for that Info. My friend at the trach was the 1 who mentioned that if I were to tray my HV's I would increase IR! Now I will Tray them! Question: I discharge using my turbo, 20 Amps right? then after that do i still put them on a small tray? thanks a lot!

Hey Danny, I just bought a couple packs of HV's and a new Integy 16x9 charger. Since the Integy only discharges at 20 A, should the peak detection change any? And would any other settings change when I go to cycle them?

MOTO: I discharge at 30 and then put in a tray. Make sure every cell gets a good contact on the tray.

Flash: I would use .07 or 70 mv for peak detect. Cycling should be done using the same setup as a T-30.

On a semi-related topic, I plan to retire my 1700's and Tekin Reflex charger in favor of some 3000HV's. Seeing as how I will need a new charger, I wanted your opinions on what chargers are most appropriate for the HV's and how important is it to have an adjustable delta voltage peak as opposed to the 'automatic smart technology' that some cheaper chargers have?

go w/ either the integy 16x9, millinium pro, or if you're sponsored by visa...go for the turbo35(i had a good run in vegas, and the bellagio paid for it). i have all three (but i sold off my 16x9-nothing wrong with it, but what am i gonna do w/ 3 chargers?) all three charges have worked very well and have kept my batteries in great condition.

Cracker78: I would reccomend a high end charger that has adjustable peak detection. This way if a new cell comes out and needs a different peak detect to get maximum performance your charger will handle it. With the price of high end batteries a highe end charger is a good investment. The Competition Electronics Pitbull is a great charger that you might want to look into.
