No problem Blueboy, here's the results of the pre-worlds, won by Hara recently.

Orion & Reedy cells have the most in the top finishers, I've got the Orion's myself and I'm very happy with them. I know other people using SMC's and they're swear by them.

Bear in mind there are six different brands here in the top 10 & any one could have won on the day.

Touring Car Pre-Worlds Final results:

Hara /Japan HPI Team Orion
Surikarn /Thailand Tamiya Reedy
Hirosaka /Japan Yokomo Reedy
Adachi /Japan Yokomo Reedy
Tosolini /USA Yokomo Fantom
Groskamp /Holland Xray Peak
Kitazawa /Japan Yokomo Reedy
Kauppinen /Finland Xray LRP
Spashett /UK Losi Trinity
Jansen /Holland HPI Team Orion

TQ: Atsushi Hara /Japan HPI Team Orion

Keep in mind that there are only two makes of batteries, Sanyo and Panasonic. Also remember that you can not buy from anywhere as good batteries as Hara, Masami and Surikarn are running. They always keep the best ones from their best drivers and their friends. So a company from where you can get the best cells is in theory a company that matches a large quantity of cells and has a small quantity of team drivers and special customers.

Im seriously thinking about getting some of these HV cells now, after vowing to leave nimhs alone for another couple of years because of the uncertainties with charging/discharging/cycleing/storage/etc etc, and also because I mainly run stock touring cars and 'regular' 3000s lacked the 'punch' of my 2400s, although they did gain a load of runtime which I dont need in stock racing anyway. What I would like to know is, do these HV cells still give the same amount of 'punch' or more than my 2400s (see above for specs on these). I presume they will gove more of both, punch and runtime, but I would like to make sure from people who have used them cause its a lot of money for a poor little student
Thanks in advance guys

I will try to explain a few things that makes one companies cells different than another. This post isn't intended to come across as SMC being the best but it's just to explain differences in matching.

Yes all matchers work with the same cells but the way they are matched and zapped can influence the packs performance.

Every company zaps their cells and most have their own custom built zappers. It's impossible for every zapper to be the same. So the company who spends more time trying to get the best possible zap can have an advantage.

The way you setup your matching equipment to charge and discharge can have an effect on the cell and will also influence the numbers. I recently built a pack of one of our competitors and the numbers were 371 and it cycled out to 355 on my T-35. I then built one of our 355 packs and it cycled out 356. I don't think that the 371 pack has false numbers but the way they programmed their machines and number of cycles they put on the cells will make a difference in the numbers.


In the end I would like to point out that there might not be a big difference bewteen companies matched packs but there is has to be one because of all the different variables involved in battery matching. Most racers may not be able to feel the difference because it's not a major one but there is one.

"while Panasonic is launching their 3000 Ultra Metal, Sanyo has their 3300HVR; "

Danny, heard anything about this?

Have a look at the shizuoka show thread...

BlueBoy,
Gear down a tooth (48pitch) or two teeth (64pitch) if you make the switch to SMH's or HV's.

I have had HV's for several months now.....and just did not like them in stock.....until.......I geared down just a touch.

Boom......most of the punch was back......and the laptimes were as good, if not better than my best 2400's........and they stayed the same from start to finish.

The HV's stayed snappier for the first 2 minutes than any of my 2400's did........so......I will be buying more Sanyo HV's.

Good luck!

Thanks for the tip acloco!
My 2400s give awesome punch (charged at 6 amps for a 4 minute race) until around 3 mins then they go soft. Hopefully these HVs will keep the car going strong until the end.
I should be getting them next week now!!

One of the big things we found out when we started zapping cells was that you needed to gear down to use the extra voltage.

I would imagine that the extra voltage that the HV's produce over the 2400's might need a gearing change also.

No news on the HVR yet.

What exactly is "zapping" ? Why is it done? How long does this "zap" effect last in terms of charge/run/discharge cycles? Are their any adverse effects?

Zapping is used on virgin cells to decrease the cells IR and improve the average voltage. If you take proper care of your cells it should last many cycles.

The process is dumping thousands of amps through the cell in a fraction of a second. This alters the cell and improves it with no negative effects.

Do any of the Brits on here know if the Reedy Extreme 3000HVs are out in UK yet?
(Sorry Danny but I really like Reedy. If theyre not out I'll get some of yours, I promise )
