I saw this on an america forum, it states it 30mm tall in one section of the website, and 20.8mm tall on another section.
if it is 30mm tall then would that make it 'ilegal' for ROAR rules (and I believe BRCA are following similar sizes to ROAR) |

plus the BRCA have stipulated that cell construction is 2 in series.... so unless they have managed to squeaze in once MASSIVE cell either side....

I think those rules are 2 in series, any number in parallel.
I think its another way of saying 7.4v nominal for the whole pack. this is just my interpretation of the rule though. |

Great stuff - just what I've been waiting for - £69.99 so not too bad.
Just gotta save up for one now!

Don't get hung up the BRCA 'Rules'. There are no BRCA lipo rules. There is a set of BRCA lipo usage GUIDELINES and a set of rules adopted by the only BRCA class to sanction the use of lipo which was agreed at their AGM and the rules were specifically tailored to the class in question. (So all you other classes out there get your act together for the next round of AGMs and get voting )
The number of cells in series only sets the max voltage limit. There is no specification for the number in parallel, only a capacity limit set at 5000mah , which once again only applies to the TC Pro stock class, no other classes. The use of lipo at club level is entirely at the discretion of the club and for each club in question to set their own lipo rules, regulations and guidelines. |

them rules is rules, and it leaves a grey area, but it does state TWO cells, and I know it is aimed at the Pro Stock class in on-road, but that would mean there would need to be an adaption of the rules put forward at the next AGM

The drawing for their 5400 inline lipo shows a height of 23mm. So I doubt the 4800 saddle would be 30mm, but until its clarified, its not worth the risk to buy them I guess. |

size is 30mm (as my prototypes) tall the (spec section is correct) weight is per cell so double it for saddle packs 126g X 2 so 252 grams total, doing my best to get finished vesrion for worksop RE the BRCA rules Hairy spider has given near the same reply i got from the EB when i mailed them, the spec's used ARE for TC class and they are/will be looked atto cater for other classes (such as off road) so get a good proposal put in for the agm, i did point out that the 2 cell's ruled out saddle packs, to which i was told, to read the whole lipo bit on the BRCA site and note this sentance The following guidelines and rules are not a definitive copy ‘Set in Stone’ and may be subject to amendments as the Racing Season progresses and more information is gathered hope that clears some bits up for you as to where you can buy them, they have anly just been officially released at the model show MarkC

got an email from Trakpower today (asking about size and weight...)
Quote:
BTW if the weight is 2x126g then the pack has a weight of 252g... AND I don't like that they don't identify their pack as 2s2p or 2s1p if the height is 30mm then I bet it's 2s2p Micha |

saddle is 2s3p so each bank has 3 cells in parallel to get 4800mah, and two packs makes the 2 serries to get 7.4 volts as i said in my post the spec page was correct!
