Default Best high performance Lipo's currently out

Hi Guys
Some help/advice would be very much appreciated.
I'm getting my car ready for the 2014 BRCA outdoor championships and I need some Lipo advice. The car spec is as below and it will run in the modified SuperTouring class.
TC6.1 WC base with RSD and EXotek mods (floating horizontally placed servo, floating Lipo set up. DCJs. Ceramic bearings. TRF aeration dampers with HPI and RSD springs)
LRP Works Flow esc
LRP X20 4.0T with 13mm team rotor, alloy vented end cap and ceramic bearings.
Sanwa servo
Ko Propo radio gear
Sorex BRCA control tyres
LW protoform Mazda 6 body with MR33 wing

I have been using some Revtech formula X Lipo's for testing and club races. But they are not (as yet) BRCA legal. Any advice what other top end Lipo's I should consider e.g. The orion 8000mah set, LRP, GM??

Thanks again
Tom

Two things.

Lipo's are not the most important thing when you have a 4.0 in the car. Just be sure to get one that doesn't overheat and puff and you'll be fine. Any of the more popular 6-7000mah packs should be fine.

Also, dump the 13mm rotor and get the 12.0mm version. LRP motors have a huge low to mid range power band out of the box that you don't need to promote more power down low with the larger rotor in a 4.0t. The 12.0 will be easier to drive, have more top end on big tracks and run cooler.

Thunderpower. End of.

I would take the advice of the previous poster about motor because he clearly knows what he is talking about. I used X20 5.5 boosted I can assure you there was no shortage of power.

Hi and thanks for the comments so far.
I don't imagine there is a massive amount of difference between the various makes and I agree it will be minimised with a already quick motor.

Regarding the rotor, I sent a day doing back to back tests the all of the avaliable rotors for the x20 and overall I preferred the torque curve on the 13 it wasn't as vital as you might think. Obviously you have to take esc set up and car set up inc gearing into account but all being equal I preferred the 13.

Thanks again
Tom

hi tom,i have run hpi plazma 6500 95c all year in 13.5 and they are still going strong,highly reccomended,but you may need a bit more mah in mod,ive gone off the ip lipos as the 4 shorty versions my son has used in blinky have all puffed up,i got him some 5300 turnigy nanos which seem very punchy

Huh, interesting.

Did you use the sintered or works team rotor?

Been looking at the dualsky lipo's, anyone have any experience with these, or know if they are the same as some other batteries?

The dualsky batteries use a 4mm connector unlike the orca which uses a 5mm connector though

Thanks guys I really appreciate the input. It's not an easy choice.
I think I have narrowed it down to Thunder Power, GM Vmax, or SMC.

I would really suggest people have a go with the 13mm rotor it doesn't give the response you might think. The alloy vented end cap on the X20 makes quite a difference too.

I have posted a link to some pics of my car on the TC6 thread if anyone wants to take a look. It's got quite a resemblance to the new TC6.2 as it uses Tamiya style hinge pin blocks and a floating horizontally mounted servo. I really like the change the dual bell crank steering made, I was initially concerned as the car seemed to have lost quite abit of steering lock overall but on the circuit it scrubs of way less speed and appears to steer more so win win!

Thanks again guys, now to start pricing up the Lipo's above and make the purchase! I will let you know how the my perform in comparison to the formula X packs I currently run.

Tom

I run my thunderpower 2700mah/3300mah lipos against the 7000+mah lipos of my competitors, and I can hardly tell the difference down the straight... That's in 17.5t blinky.... In mod I run the Tp4200 40C lipos with my 3.5t Car and pull them down the straight easily too. I don't run boost though... So my conclusion is that all the batteries that are at or above the Tp4300-2spr65d level will not differ much in performance, stock or mod........ I am sure others will disagree, but that's my opinion: save your money !!!

Except Turnigy Lipos are not BRCA legal and the question included that he wants to run in the 2014 BRCA series

It is up to the manufacturer to submit batteries for approval. If this has not been done, they will not be legal.
