Cool thanks Dan if it is that long I should just make it. It is only a small club race so there arent that many heats. Is there a particular brand/model discheage try you would recomend right now I have the INDI reactor 20A. I wll try to get it mod. to 30A then would like to tray them to equallize the cells, but you say with NMh you need to take them off when the lights go out, I would hate to be doing something and just forget about it.

Default What voltages are we talking about??

I have two HV Orion Team packs and their voltages are 1.149 and 1.150 at 30 AMPS.

The other day, when talking to a sponsored driver he told me that his packs were also Orion (10 of them) with voltages of 1.189!!!

As you can imagine I was amazed.

Did any of you come across these voltages (at 30 A, of course)??

Danny,

If you did (for your team drivers) a simple no comment is enough LOL.

Default No way Jose

..maybe at 20 amps.

I got a battery sponsorship and my best packs so far are 1.162 @ 30 amps and they rock.

I heard Trinity brought their factory team's cells that were supposed to be used in South Africa at the offroad Worlds in the summer to Oktoberfast in Minnesota and the number were around 1.19 at 30 amps. There were only a few of these and they sold them to the public.

Buda: Use a bunch of 1157 Automotive lights in parallel to discharge your packs with a cutoff device. I don't think that a discharge tray can discharge at a true 20 or 30 amps.

Stefan, I am jealous.

Orion uses a Lavco matching machine which cannot be compared to the CE machines most U.S. matchers use.

To add to Danny's post, Ohm's law is V=I*R so transposing this figure when voltage (V) goes down so does the current (I). Unless you are able to vary the resistance.

The highest voltages on the HV's is 1.16 and true 1.16's are not very common.

Be aware of the hype or what others claim to have seen or have. If it's to good to be true then it probably is.

Yeah that's why I asked.

When I see numbers like that coming out of nowhere I always doubt it.

But because his packs are also Orion (match at 30 A) and he's a factory driver I was just amazed.
If my packs are awesome, imagine those...1.189 packs!!!!

Those numbers seem to be at 20 Amp. Such a diference in voltage would be almost impossible. But who knows the misterious ways of the hobby?
Not me for sure, I just spend my hard earned money to be beaten at the track .

But I admit that I would buy those packs in a blink of an eye.

Default Help from a Newbie

I'm new in this hobby and just bought a 3000HV batteries (not matched) for me to start with. And also have a Millenium V1.2 Charger (that's all I can afford now). And this is my first time using NiMh batteries. My question are:

1. What are my charging parameters for this HV Batteries using my millenium v1.2 charger? Or what would you recommend my settings in charging this batteries.
Voltage Threshold; Ampere rating; etc
2. If I want to have more power or what they called punch, How do I achieve this using my charger?
3. Using those parameters you recommend can I assume my batteries will last at least a year or more.
4. What would you recommend in discharging HV batteries?

Please excuse me for my questions and still very new in RC.

Thanks,

wacky - browse though the whole thread. There is tons of great information that have already been talked about in here, most of it going with charging and discharging.

I got my Team Orion HV cells. My first use of them won't be until late February. Is it okay to assemble my packs even now ( 1 1/2 away from it's first actual use). I'm wondering if it makes a difference.

So far the HV's seem to have a good shelf life so you can build them now or leave them unassembled and it shouldn't make a difference.

How do nimh cells hold up to long term storage compared with nicads?
I am a student and consequently have to give up racing during
term time. This seems to have totally killed my 2400's, so I am looking for new cells. They were discharged to 5.4 volts and then stored. Is the only answer to train my parents to cycle cells?

Danny, how have would you recomend storing both the SMH and HV's? I have been taking each down to 5.4 after a run then traying them for 5-10 minutes. The next day I put 10 minutes charge in them. Then the night before racing I take them back down and tray them again. Is that OK?
