1s lipo 65c/50c
Hi I'm about to buy 4 new lipo packs to replace my Nosram 5400 50c packs.Was looking at the new CRC 6300 50c packs.But i notice that the new nosram packs are 5800 65c
does the 65c make much or any real difference to the performance of the car packs are used in a CRC gen-xl 12th with a tekin rs and tekin 10.5 redline Gary:( |
if your racing National events the batteries will need to be on the BRCA list

was just wondering if there would be any difference in performance between a 65c or 50c pack in real terms Gary:thumbsup: |
It's too close to call. Given that the 'C' ratings are about as accurate as the capacity and voltage numbers on NiMh cells (ie, not very!) then they have to be taken with a pinch of salt anyway. If you are running a 10.5 motor which is probably 250W at best, then (W=VxA) you aren't going to draw more than 80 amps continuously, so having (50x6) 300 amps available is rather academic! Which leaves us with the capacity.
Those numbers are usually more accurate, and they do get checked by people like ROAR and BRCA as part of their testing for homologation. Since most people can check this on their chargers too, the manufacturers tend to be less *cough* imaginative with these numbers. The more capacity you have, the less voltage drop you get during the race. The less voltage drop you get, the higher the performance towards the end of the race. If you are going to run in the new 10.5 Stock class with no timing boost, this will become essential. Given those cells, I would choose the CRC 6300 cell. HTH :) |

Thanks Gary |

However, I do know that there are moves afoot to use a standard test proceedure to compare the performance of a number of the packs currently on the market. |
Tom, I know there are no Rules for capacity, I was only pointing out that they are tested. This gives the homologation boards information about how cells are being developed. The capacity is one number that is less *cough* variable as most people have some sort of reading from their chargers, so if the manufacturer was making a big exaggeration, the customer would soon notice! The 'C' number, on the other hand, is never checked by any charger.
In my experience, if you buy cells from reputable people like Thunder Power, Orion, LRP and SMC, you get what it says on the label. I've heard more complaints from people who buy 'no-name' packs. I've been using SMC for the last 18 months, and my three well-used packs are only just starting to get tired. They've been great, and I would buy SMC again, but that is just my experience of one make, and not a dig at any other. |
i have run 5000 45c orca 1s lipo in my mardave and yesterday i ran some lrp 5800 65c man what a difference so much more punch out the corners
i ran it in a dave with the gtb2 no booster cos the gtb2 doesn't need it and did my best lap time and laps with them i will be getting another :thumbsup::thumbsup::thumbsup::thumbsup::thumbsup: :thumbsup::thumbsup::thumbsup::thumbsup::thumbsup: :thumbsup::thumbsup::thumbsup: |
