There are ROAR legal already.

This is not a new cell, just an improved cell. Still a RC3000 Sanyo. ROAR regulates the cell by size and capacity, not by the quality of voltage output.

The black Panasonics were also not submitte for approval for the same reason.

Sorry guys if I didn't get to answer all your questions. What I have learnt and reccomend for the RC3000HV is posted on our website.

If something isn't clear or you have other battery questions please ask again. I will have more time to answer on Tuesday.

SirSpeedy is that for sure?

Danny /SMC whould you use the same charge/threshold numebrs for SMH's as HV's? And is cycling HV's once a month considered excessive cycling?

HarshGUY: No I wouldn't use the same peak detect for the SMH's. A .05 seems to give good results with the SMH's.

Cycling once a month is fine. Remember only to use a 1 peak charge. The runtime will be lower by 3-5 seconds but I believe this is better for the pack.

How about the cycling done during matching? Will that hurt the cell?

Sirspeedy: good point about the Legality. The SMH were legal when they came out, so it shouldn't be any different with the HV's.

GKC: No the cycling during matching will not hurt the cells if you setup your equipment correctly.

You can cycle these packs without any problems it's just that in my initial tests I was cycling the same pack 2 times a day everyday and it did show some signs that of wear but I was also using a 2 peak charge. I have tried the same test with a one peka charge and it's better. The RC3000H would lose voltage if you didn't cycle them often. This new cell doesn't have this problem so there is no need to cycle them often.

Danny,

got a question for you.

I'm running SMH batteries.
I have not raced them for the last 4 weeks, but cycled them every week.

Now, since I read that you shold keep the cells as cool as possible during cycling, I got me two PC fans and built me a little stand where I put the packs in for cycling.

The first cycles afterI got the fans made me almost go nuts.

My ususal numbers are ~420s/ 6.95V @ 25 amps.
With the fans, the numbers were 395s/ 6.70 @ 25 amp

I thought all my packs went south.
After removed the fans, my numbers went back to normal.

So, does heat hurt batteries or is it necessary to get performance?

Thx

I almost forgot till I saw stefans reference to packs going south, I do have 1 SMH pack that is dead, one cell is completely dead no voltage at all ...where can I get individual cells? Or can I maybe send the other good 5 cells to you Danny and you can match up another cell to it? This is a Trinity SMH matched pack.

Stefan: I never said to use a fan on cells while charging. This will not get the cells to charge correctly and as you can see it affected your numbers.

Heat is alright as long as you don't overcharge the pack it's o.k..


Harshguy: Sorry I can't help you with your SMH's were out of them and don't plan on getting anymore since the new RC3000HV is doing real well. Plus I would bet that your other 5 cells are all over the place and not well matched anymore.

Can you use these cells 3-4 four times a day as with the SMH's?

Our tests conclude that they can be run atleast 2 times a day. I have never tried 3 or 4 times. If SMH's can I think this cell could also.

Darren shank is sponsored by Fantom, so you guys too I guess...ANd he was running his SMH's up to 4-5 times a day. I need some new batteries, and the appeal of the SMH's is that you can run them alot...Would be nice if you can with these too.

In my experience, you can run them very often.

You do need to let them cool down all the way. This takes at least two hours. Even though they feel cool to the touch, the core of the cell could still be very warm.
