IB has submitted some cells for IFMAR approval. I think the sanctioning bodies should update the current battery rules which have been in place for many years. The newer generation cells and todays motor technology could make 10 minute RC races possible.

With the current smaller diameter IB cell it can compete with the GP cells and hold its own. IB will most likely have to increase the diameter of its cells to be able to get more power and capacity. The current cell has great performance but it's the smaller in diameter than the GP3300.

Danny any testing done yet for cell capacity and performance after extended amount of cycles, say after 30 or so.

I have to disagree with you on this one Danny. We will probably see 3-4 new cells come out this year. I dont want to have to rebuy packs that many times a year as new stuff comes out. Once a year approvals are fine with me. Maybe they should update when cells have to be submitted though. I think 4 months before the next season is a little too far out, maybe have new cell submissions in by November.

Bob: Josh mentioned that the packs he has been using have given him consistent performance on the track and that is after running them up to 6 times per day. Guess we will find out as more racers get them.


Jack: I'm not really worried about the way we have to submit the cells but I think that the size rule could be tweaked some to be more in line with what the cell manufacturers are doing to make better cells. The RC market isn't the only market to use high end sub-c cells.

I can agree with that, the size parameters don't bother me much, as long as they fit in my car. Isn't there a global standard for a sub-c cell though? Are the new cells getting bigger than this or do they still meet the standard?

Supposedly, yes, there is a global size standard.

SC (sub C) 23mm dia 43mm length with a +-1mm variance.

You can find this information in many places including:

http://www.dantona.com/pdf_handbook/page_87.pdf
http://www.powerstream.com/Size.htm
http://www.gpbatteries.com.hk/html/t...racing_car.asp (note, GP's website. . .)

Seems to be fairly well accepted.

So far were not aware of an IB3800 but once the Chinese new year vacation is over I will try and get answers.

Danny, should I bring these cells down to 0.0 volts? On an equalizer of course. I am racing 19 turn asphalt and need a balance of punch and top end.

So far we like to bring them down to .90 per cell and leave them alone. You can palce them on a tray before you charge them.

I cycled my pack of UNMATCHED, UNZAPPED 3600's a couple of times on Friday.

Their initial discharge voltage (off a T35) was as high as a matched pack of 1.180's (from both PMR and SMC. . .)

Their punch wasn't quite as high as my main packs but they didn't seem to soften until WAY late in the race as opposed to my GPs losing their punch at around 3 mins or so - you know what I mean?

Love these cells.
