Default Panasonic ULTRA METAL or SANYO HV is better ?

Hi,
I would like to know which one of these batteries is better. For Stock and Mod. I heard the panasonic has better voltage output than that of the HV and that is why it is punchier than HV for stock. Just wanna know your opinion. Thanks. Cos I would like to invest some, sometime end of the year

Personally I don't think you can go wrong with either one. Here in the U.S. at the Snowbirds race in Orlando Florida the mod sedan guys were running the Panasonic cells where as most if not all of the oval crowd were running the Sanyo cells. Just something to think about.

IMO I feel that the sanyo HVs might be the better battery being that they cost less (at least orions do) and they seem to be alot more durable. If you, however, are more careful than the average joe like me with your batteries, then the ultra metals could be better (I've personally never tried the UMH's, I've only been told how they perform by other users at my track)

I have both the Panasonic SMH and Sanyo HV. Both have advantages. HV's charge to higher voltage numbers (t35). 9.33 to 9.45 range for the 3 sets I have. However runtime is lower ~ 375 sec (25amp). SMH give me 9.00 - 9.03 peak voltage but the runtime is 425 sec @25amp Panasonics have lower IR numbers than the Sanyo.

So which means that Sanyo HV is more suitable for STOCK racing as they have higher voltage ? So the motor will have more punch ? Hmmm ........... Maybe I should get one each to try first. anyway, thanks for the info guys ..........

Only buy the UMHs if you have a very good charger with adjutable delta peak. The Panasonic cells are more sensitive to overcharging and have a narrow peak charge range.

You might consider SMHs vs HVs. I hear they are better for stock.

Not really...higher peak voltage indicates higher IR......

If you are using an older CE Matcher to match batteries then the I.R. number you get is the result of a calculation made using the peak voltage and another factor.

The newer machines calculate I.R. in milliohms. I am not sure about the other types of machines that are out there to match batteries.

I'm going to be buying some packs in a couple weeks probably. I've got 4 HV packs, they're all about a year old, punch is still there but runtime has dropped off. I'm planning on running these packs in stock this winter, but I need something new for Mod. I'm really thinking about going with 3300's, because hopefully if (when) I get a little excited and over drive the car for a couple laps, I could still make runtime. But on the other hand, I've heard of lots of people using various 3000's with great success. So, anybody have any reccomendations for which packs to get for 5min Mod Sedan???? I usually run 9, 10, 11 turn motors.

I just check out tower hobbies and it seems that Trinity has discontinued the 3000HVs and they have release the 3300 from GP. Hmmm....... I am now wondering how soon will it be before Sanyo or Panasonic come out with the 3300 ?

TowerHobbies lies about discontinued stuff. I think they mean THEY discontinued their stocking of the item. When the merge b/w Losi and Horizon occured.... it said LOSI XXX..... DISCONTINUED.... so I am sure 3000s will be around for quite awhile.

Panasonics for me, my SMH and Ultras peak between 9.1 - 9.2. The HV I had was peaking at 9.43 but I sold it. All I have now are Panasonics.
