ALL cells.....

G

Im gona wait till all the rules are released as ive had my cells for ages, so gona wait till i know what i can get that will be legal for regional and national use.

So cells that were previously approved for use may be removed from the list?:o

thats what is worrying me.

How do Col for most of us I dont think that it is buying new cells it is the old cells that we already have, that where purchased after looking at the homoligation list and not expecting them to be elegal just a few months later. The national series does not cost that much but for us lower order stalwarts it can be hard to find the money for new cells.:)

and me:(

if IB4200 become illegal, I will have 15 useless packs.

this my point:mad:
does the electric board cover all brca catergorys ie touring cars etc cause i did a ruff gestimation that pretty much all cells will fall foul of new rules ie 4200(if its the case) theres probably about 5000 racers racing up and down the uk electric using five packs minimum so a rough figure that 125 to 150 thousand cells need to matched to be legal its a bit of a mind blower it takes at least an hour per cell to match 1 cycle i dont see how the hell its going to be viable:eh?:

i take it the brca will refund you for the illegal cells lol
yeah right
but all guess work till the new list is released

To be honest i did not think that lipos were mainstream yet here in the UK in offroad, if i had known i would of put a proposal in. I think stick and saddle hard cased lipos will become more developed during this year, so safety is a none issue and hopefully we will be able to run them in 09 :)

personally i could not give a toss cus they do what the hell they like but i enjoy racing and would like to know wot i can use this season and the mushroom managment approach is doing my head in. plus i wanna now wot ive got save up to pay for em and where can i source em from:D

LOL, have you read your handbook? ;)

I don't think that is a fair comment, considering previous rules were that all cells once homoligated will remain on the list. Therefore if we went back 12months, 24 months or whatever, we'd have been fine then buying any legal cells ready for the following season - even though there would likely be a larger capacity cell allowed for April 1st.

Perhaps the BRCA should not have turned a blind eye to the dimensions back when our current legal cells were made legal, and we'd still be happily running GP38's... but hindsight is a wonderful thing, and I don't know all the facts.

What would be a fair comment, is that this rumour/whatever it is, we are all aware of it and have been for some time - so shouldn't be buying news cells til this list is published.... who it is unfair for are those who rely on either making cells last as they run a fleet of cars (DCM) and those who buy 2nd hand cells from those who don't keep them long...

This pot is boiling, im rather anxious to see the published list too...

from RCRacechat, apparently there has been quite a few samples sent in for homologation.....

As for the list, what is on there is normaly left on there, so you can buy with confidence, but this issue that certain cells maybe be removed (and probably the most popular cell too) is making lots nervous.

max amps and precision rc will make a killin:o

im getting ready to dig out the old gp3300 :o:eh?::D

A

:yawn:

Thats why you should run gp3700's, Ive got 6 packs of those and 4 packs of 3300's. GP FTW!!!

How very odd, i think i have the very same combination of packs lol!
I presume the fact that cells are blowing up are the biggest concern rather than the size of the cells.
It is a shame for people that have gone out and bought 4200's but i think safety will be a big issue and also if cells are blowing up in cars it will most probably be taking the other electronics with it thus more money to spend!

I cant wait for "the list" to be published.
I have 6 packs of GP3700's they are ok(ish) in 2wd but i cant use them in 4wd cause they old, and my reciver keeps cutting out. I am ready to order 6 new packs of cells but which?,

You cant say without the list being published. Patience is NOT my strong point.

As you guys will not read the rules here they are.

3.1 Cells submitted for approval prior to 01.01.06 have to conform to 2005 BRCA EB rules. The following technical specifications follow the rules adopted by EFRA and will apply to any cells submitted for approval from 01.01.06.
Only rechargeable NiCd or NiMH cells rated at 1.2 volts nominal will be allowed at BRCA sanctioned events. The size of the individual cell(s) to be:-

• Diameter -- 23.0mm +0/-1 mm
• Overall length -- 43.0mm +0/-1.5 mm

Measurements include original manufacturers heat-shrink. Overall length is the maximum length before attaching/soldering any link wires or battery bars. Dimensions taken at ambient temperature, and apply to new/unused cells as submitted by the manufacturer. Cells must never exceed 44.0 mm length after any ‘matching’ or charging processes. All cells must have the original manufacturer’s heat shrink substantially intact. Weights of submitted samples will be recorded to verify that production versions compare. From 2008 onwards, it is intended to amend the rule that cells must never exceed 43.0mm (including any distortion from charging).
3.2 All rechargeable batteries must meet BRCA specifications before they will be approved by the BRCA Electric Board. Details of newly approved rechargeable batteries will be published on the BRCA website. Only batteries appearing on the official BRCA website homologation list published in January will be legal for use at BRCA sanctioned events from 1st.April of that calendar year

What this means is it does not matter what cells you buy if they are over the limit then they are illegal.


This has not changed for the last 3 years.




You can measure the Dia now The overall is very debatable because of solder ect and as said before if you are in the A final at Euro's worry about it if not do not.



To Answer another question BRCA members do not have a say in these rules, only the electric board and yes it is for all classes, off road and on road.



What you need to ask is if I have 5 good cells and one bad cell what happens. Yet again a rule with not enough information.

Just looking at the BRCA homologation list of batteries for 2007, a lot of the batteries listed were very difficult to get hold of, even suppliers were finding it difficult to sorce batteries early in the year. I can see a bit of a rush coming on when the lists are published.

there appears to be some misconceptions here, firstly the new rules are not new as ptru has pointed out the dimension change was published in 2005, manufacturers were aware for nearly 2 years. the issues over IB's blowing up in the last few weeks are irrelevant to this, the new list will be based on dimensions not on any safety issues.

usually batteries that were on the list in previous years would stay on there, however that assumes that the batteries are the same as the ones submitted, in the case of IB's they have grown in length over the last year and are actually i believe outside of the old dimension rules, it also assumes that the batteries submitted for testing are the same as the production ones!.

What concerns me about this thread is the lack of respect for the BRCA officials who undoubtedly spend a lot of their trying to make our sport work safely. Have any of the people complaining actually contacted Paul Worsley about this issue at all???

THE LIST ISN'T EVEN OUT YET!

Yes they have Super Dan

No body is dising BRCA.

i think ive been good i didnt diss the brca

A

Dan, I don't think people are for one, dissing people carrying out the work in their spare time, what is being talked about is the uncertainty over the cells on the current list and will they be there on the new one. In previous years they always have been, the difference this year is that there could be some removed. So the BRCA could at least confirm all cells on the list are safe or no

the EB list has been updated for 2008 if ive read it correctly the EP 4200's with the back discs are now legal i think but dont take my word for it read it for yourself on the brca website but all the usual GP IB EP cells are on there i want som eof these GP4600 :)

A

Just been to the EB site .... homologation lists are unchanged from before Xmas .. or am I missing something????

List is unchanged - the clue is that it is dated as April 2007.

Glad it's not just me....

Ashley ... care to post a link to the list your looking at please?

rog i think a crystal ball is needed lol;)

The only thing i can see is the 2008 regulations not the Homologation list.

look further into to the ball i see no intellects lol:eh?:

It is there it's on the front page and also under the electric board under regulations 2008. But all it says is the size of the cells really.

Just wondering, how do you measure the length of a cell accurately? surely a micrometer or verner caliper gauge will be required? if you put these accross the terminals on the cell, won't it short the cell out?

Not if you put a bit of insulating tape over a contact :p;)

It's not up to you to measure your cells and decide if they are legal or not. The EB measure the samples or cells they get sent for homologation and say if they go on the list or not.

Simple.

Wait for the list.

G

I hope this is an industry standard thickness of tape i dont want my cells scrubbed of the list cos of some fat tape;):D

Yeah, I know that, I was just curious. I can't measure my cells as they are covered in solder. ;)

Plastic verniers? we have some at work, not because they don't conduct but because they were really really cheap... I think it was a couple of quid for the crackers? :D
