Your own choice of not owning a charger for the only legal cells, can't blame the BRCA for that really.

Here's a thought,

Why not propose that the BRCA allows the current oversized TrackPower lipos, on the condition that production of these stops and replacement products are made to the rules?

This way owners of trackpower lipos will be happy, people will still be able to buy them until stocks ends, and trackpower will be happy, the BRCA would be reasonably happy as the rules have only been bent for products that were there before the rules and not after.

Jamie, we were given assurances at the agm that everything would be done to get the info out about what would be legal as soon as possible to avoid the situation of having to get cells at the last minute like earlier this year.

I still think all this would be cleared up with a 2 year grace period giving you 1-2mm in tolerance.

Allows current packs and no manufacturer is going to design a pack with a shelf life so short.

Who says we will be using lipo in 2 years time, i think this was one of the brca's issues with them, there is new technology in the pipeline that in theory will be better.

Surely that gives more reason to allow the lipo's people have so they dont have to out and buy new lipo's to replace perfectly good ones. Thendown the line with the lithium A123 stuff upgrade again ?

I would not be surprised if the current saddle packs were as small as possible already, trackpower or any one else may not be able to meet 139mm with 2 packs, if the height dimension is a typo, then that makes it even tighter.

but were trying to aloow cells that dont give an unfair advantage and its the case thats over size, not the cells!
seconded!!

the internals would more tha likley be the same, just half to 1mm taken of the case size, hey maybe even a thinner case and sod the saftey!!

maybe the company are not in bed with EFRA?

Maybe make some of the internals external? As I understand a fair amount of space is taken by the plugs, how about removing them from the case and have them on a wire coming out, with good heatshrink it should be no problem...

I guess that could be considered as being similar to the way GP were "encouraged" to shorten their slightly "lofty" 3300 cells a few years back :confused:

Mark, i'd be careful making too many "suggestions". Various respected/experienced companies are Associated members of EFRA, as i'm sure you know. It's obvious that many of these companies are present at the EFRA meetings to advise on what they see as happening in the future.

thats was my point matt, one of the companies had a pack thatt was too big in capacity and hey presto the capacity is lifted

and the pack dimension limit 'just happens' to be 1mm shy of the trackpowers..now whats the chances of that.

so penalize somone for having a neat wire free package, or should we take all wiring that comes with the pack into the dimension equations?

question for you if a pack in use has broken insulation on the external wiring to the pack, and shrts out for saftey reasons how are you going to disconect the wire from the pack, yup you can unplug the pack from the car, nope you can not unplug the rest of the externat wire from the pack!

trakpowers you unplug the external wire from the pack, no external wires to short out

which would you say is safer?


bear in mind a new case could be designed and possible made to fit the "rules" but that is at a cost, and we all know that part of that cost would be down to racers to cover

I'm only feeding ideas to get a saddle that fits the rules.

There are Lipos out there that have wires coming out, Core RC for example, so i don't see what the problem would be... I don't run trackpower and my sponsors are unlikely to release a saddle pack so i really couldn't care less tbh wether these get legal or not, I'm gonna have to run NiMH in my 4WD.

fully appreciate that fabs, but there is a saftey point that you can not disconect external wiring on the pack in the even of a short

if it is such a big issue why are the core rc paks legal then ?

cuz there not saddle :p

But they have 3 wires poking out and going to a single plug which makes them more dangerous than a saddle with a single plug at the end of a wire at two totally different ends of the pack.

Fabs there is no rule re wiring, im pointing out that they may not be as safe
