John, THANKS!

Do you think I can cycle them using my LRP discharge tray, it discharge each cells at 3amps

I will put a full charge in them after

But will using my tray will make them run flat? (dont have a high amp discharger)

You should buy an Indi Reactor 30 from Integy. It's relatively cheap and discharges at 30 amps.

I would discharge your pack on the Reactor 30 then place it on your LRP tray. Once each cell is discharged on the tray I would put 15 minutes of charge at 6 amps back in the pack. This should be good for one month. Then repeat the process again if you need to store it for another month.

It's important to use the pack once in practice after it has sat with charge in it for awhile as the cells need to be run once to regain there performance.

I totally Agree with billy's statementI picked up some Ener-g cells from eXpress and They perform very equal to IB's

Thanks, Danny!

I will get the Integy discharger, but I have to leave tomorow so it wont be here in time...

Shall I just charge the pack at 4amps for 10min then equalize the cells and give a 15min charge at 6amps asyou suggested?

do you think this is the best i cand do?

Danny, you say to charge at 6 amps, in the UK we are getting advised by the BRCA to only charge at a max of 1C (4.6amps for 4600mah) or the cells will blow up, destroy the building we are in and render us blind for life and maybe longer.

What is the theory behind this and is it not just an overreaction to a few cells from a particular cell manufacturer having some problems, that may now have been solved anyway?

I would just put charge back into the pack. I reccomend you put 25 minutes at 6 amps which should be plenty for 3 to 4 weeks.

Charging at 4.6 or 6 amps will not make any difference as far as cell exploding. Cells exploding have to do with the cell design. As the manufacturers try and make more capacity out of a limited cell size everything gets thinner insed and more material is stuffed in the cells. That is why I have said that the new EFRA/BRCA rules make no sense.


The way to fix some of the problems would be to go down in weight which means they couldn't pack the cells as much.

Thanks for the reply Danny, it is good to get an opinion on the new BRCA 'guidelines' on NiMH care that have been published. I personally don't agree with them either and I have always charged and 5.5 to 6 amps without a single problem.

I think it is a knee jurk reaction to the problems in Norway, and a little over the top. Some of the guidelines do make sense, but the charge rate doesn't seem to. Here is what they say on charge rate

2. Never exceed the manufacturers recommended fast charge rate. This should be 1C max., even if the manufacturer states higher. (C being rate of charge based on capacity of the cell, e.g. a 4200 mAh cell = 4.2 amps)

3 .Disregard any charge rate recommendations by the 'matcher' if it is more than 1C.

Danny - interesting idea.. exactly what do you mean by weight? Shouldn't size always be a consideration as well? How much does a, 4600 for example, weigh and how would a tech person know the cells were too heavy during a quick tech session?


Thanks!

I hear these stick pack cells you guys have are pretty fast!

Actually the current cell size is fine and they fit in all cars. I'm not sure who came up with the idea of reducing the cells length in Europe but it makes no sense as reducing the cell size will not help anything in fact it may make things worse.

The EnerG 4600 cell is 70 to 72 grams.

If we would force the manufacturers to go down in weight and keep the current size they would not be able to put as much into the cells and this would reduce allot of the issues. I think the maximum weight should be 68 grams with shrink. This means we would back down to 3800-3900 mAH and the instead of the current 4300-4600 mAH.

As far as teching cells for weight that would require a bit more effort but it can be done.

I got to run mine today and they were very nice. Lots of punch and they held on strong throughout the run.

Well...good showing for the Ener-G cells this weekend at the Novak race. Both Josh and Mike we fast and laying the times down. Brad was fast as well along with Josh. Let's not forget about Justin in Mini and I believe Hunter was running the new cells as well but I am not 100% sure. Nice work.
