BRCA EB Battery Regs Announced

[greasy mark]

beat me to it mark lol,as mark said the beter quality cells arnt folded they are sperate cells conected by welded tags .much like the make up of a sub c stick pack ,

How the plates are joined to create an individual cell is irrelevant, whether folded, soldered, electrowelded, whatever, doesn't make any difference to the physical size of the cell.
The cell consists of an anode and cathode separated by a catholyte, electrolyte and anolyte layer, making up a bipolar plate, which is flat. The overall length and width of the cell is controlled by how big these plates are cut to, the height by how many layers are stacked on top of each other (either by joining individual plates or folding one plate over) so to make a pack small enough to fit in the rules you just cut them slightly smaller and use less plates. The downside is the smaller surface area means you have less capacity in the cell.



And I've heard a rumour that some manufacturers have managed to make cells small enough to fit the rules.

i understand that ,the point i was trying to make is that 90% of the lipo cells ie each plate are made to a size most of the lipos we have for racing have been developed using existing size plates from planes/helis or any thing else that uses them so just making each plate smaller is posible but a massive investment and re tooling for the manufatures the wraping would nead to re tooled for the jigs for the welding,basicly every part of the process from start to finish would nead to be changed.i dont see why the eb cant relax the rule for a year .

guys n galls there has been over 4000 veiws of this post and most of the posts on this thread are from people that dont seam to agree with the ruel,why dont we the brca members put up an online petiton and then submit it to them.??? i personaly wont be able to do as many of the reigonals as i would like what with 1/8th buggy and truggy nats but would have done the ones i could using my b44 with trakpower lipos .i for one will not now be attending any if i canot use my lipos

Why don't you just wait and see what happens - surely that's the easy option! When a list is released, have a look and see what's on it. There are many more companies than you could realise, and you couldn't possibly know what they might or might not do.

Surely as we are the BRCA an EGM can be called if enough members call for one. I also cannot believe that no one from the BRCA is responding to the comments raised.

Speed Passion LiPo

could these metals be on the 2009 metals list also ?

Now, now... everybody just calm down and be patient!

I'm convinced you'll fully enjoy the new 1500 mAh LiPo saddles!

Some say the Stig ate a test pack in PWs kitchen, without being injured as well...

I haven't read all of the posts on here, but it seems that the saddle pack dimensions 'thing' is still going. If it is...

This must rate as a huge waste of space. Whinge, moan, rant, speculate, etc., etc... Has it occurred to anyone to ask whether or not there has been a simple mistake? Perhaps the following logic went through Paul's head, as it has through mine...

Limiting the size of the box will (for the time being at least) limit the capacity of the cells, which in turn limits the cost. However, the possibility to make two boxes (saddles) larger than one box (stick) is higher, since there is more room in a saddle pack car than a stick car. So, it would seem simple to make a Rule that says the two can't be greater than one. And then, one simply forgets that one now has four ends, not two.

So, why hasn't anyone sent a polite e-mail to their Section Secretary and the EB Secretary, pointing out this issue, and asking for an urgent request from the 10th Off-Road Section, to the EB, to get this Rule changed before any cells are approved?

Why is it so difficult to do that, and so easy to type rubbish and rants and insults on here? Nothing gets changed by typing on a forum, but there's every chance it will by typing to a BRCA Official. You elect them, use them!

This is what I did when the issue of the 'thin' LRP endbells came up, and I got an answer within a week - favourable as it happens. Come on guys, give these BRCA volunteers a break - ask for their reasons instead of dissing them on a public forum. Without them there'd be no racing, so the least you can do is think before you type, and try to see things from their point of view too.

I'll bet that if this was pointed out, the Rule would be changed.

Ok, I shouldnt speculate, but Ive got to give some hope to myself and the many other frustrated saddle packers.

These bad boys have gotta be on the list

Voltage: 7.4v 2S
Capacity: 4200mah
Discharge Rate: 30C+
DIMENSION: 69x46x23mm for each
Weight: 257g
Wire: 12AWG
Balance Change Plug: XH2.5 and Tamiya Plug
Packing: with Hard Casing

Only if they have been submitted for testing then they could still fall foul of the EB

Did you submit them or know the company that did?

By the way, is there a rule about being commercially available within the uk for batteries?

Hmm, good point dave, just noticed that there is no IP stick pack on the TC list. The Demon pack looks a bit like a IP pack ?

I knew I shouldnt speculate.

At least it shows that someone has made a pack within dimensions, and not a bad spec at that. There is hope.

They look cool.

DIDN'T JUST I JUST SAY THAT IN AN EARLIER POST WHY REPEAT WHAT HAS ALREADY BEEN SAID?????? EVEN 'rrrrrr

The BRCA measurements will be in UK imperial metric

Or maybe you should chill out, you posted while I was writing mine, so I wouldn't know you'd said it would I!??

Only just came back and saw the double post.

Maybe change your name to irritable rather than irri tant old boy...

the UK distributor must submit the pack, then, once proven that a certain amount have been ordered/supplied, if the cell passes homologation, it will go on the list.

Ask nice, EB Sec... OR chairman....
