hohen711: The HV's should be stored without any charge in them. You can leave them stored for a few months without any drop in performance. I have never tried leaving a pack stored for more than two months so I will reccomend to cycle them after a few months just to make sure. They will hold up very well to storage but you might want to consider 3300's for next season so if you have a potential buyer you might want to sell them.


AMGRacer: Is it 10mv per cell or for the entire pack? If it's for the entire pack this is way to low. Try 70 - 90 mv for a 6 cell pack. Putting HV's on tray will keep maximum voltage but will remove 165 to 250 mAh and when you take into account that only 30% of the Sanyo HV's can really give out 3000 mAh your numbers are realistic.

It is 10mv per cell, 60 for the pack. I will up it a bit and see what happens. Interesting what you say that they dont give out the full 3000mah. Anyhow the runtime is decent and the packs have great punch so I am not too fussed. Thanks.

Sorry, but all the different info is starting to confuse me. What should I do with my 3000HV's?

- Discharge them;
- put them on a tray (if I want to and check the lights going out);
- Store them for a period of up to two months maximum (as a rule of thumb, but will use them every week);
- Charge them at the race day just before the race with 5 to 6 A with about 12 to 15 mv (per cell);
- race and win
- If I need them a second time during the day I would follow the same procedure (with at least 3 hours in between.

Does this sound okay to you?!

If you ask ten racers you'll probably get ten different answers
(not intending to offend any1) coz most people will hav their own battery care regime that works for them, even batteries matchers differ in their opinions on what works.

So just follow what u think is the best suggestion and c if it works for u. u can always change if u find that it doesn't give u the results u want. Just my 2 cents.

anyway if the advice is from reliable source( e.g. batts matchers, or people that knows much about batts) It's probably worth a try.

Yes, you'll be just fine with 4.5 amps, though it will take a bit longer for your packs to peak. I don't think .5 amps will have a noticeable impact on how they run.....

yes you can charge at 4.5 amps but they may not feel as punchy...

I charge at 6amps to 8amps.

Your theshold seems low it should be between 70 and 90mV

I do not hav much experience with HVs yet, still trying them out, charging @ about 4.5 - 6a for linear and slightly more for pulse. Threshold of about 10 - 12mv per cell. discharge to about 0.9v per cell after running.
sorry that I couldn't provide more info on them as I'm setting up and running my mini-z recently. hav not been playing 1/10 for a couple of mths.

Hi,
I was wondering what advantage do you get by increasing the mv,say i charged a pack at 4mv & a pack at 10mv what would be the notice-able diffrence,
Also what mv/per cell do i use for 4-cell panasonic-stock-metal-hydride ,
& what mv/per cell for sanyo HV -4-cell
With the racing i do(1/12th-mod),im after run time,how do i get that.?.is it by charging at a low amp
Ive noticed at my local club they use 50mv/per pack)-4-cell,
is this about right for 4-cell 1/12th-8mins racing.?.
Thanx
stevie

Thanks Kino. That's close to the same info I got from some top Dutch drivers. They even tray the cells very short before charging them on raceday!

Steve are you talking about a the drop in the peak detection? or 4amps vs 10 amps can be used for charging but I never heard of 4mv charge?

I just got my first pack of Sanyo 3000 HV one week ago.

I've noticed, that while charging, they get warm quite fast. That is, they are very comfortably to keep my hands on. Then the temperature stays almost constant, they dont get hotter than that. Is this normal?

My NiCd's just get sligthly warm, at THE END of a charge...
