Lipo Experiences

what charger do you have?

how I measured this?
I just read it from the display from my charger after charging was complete.

I discharched my Lipo's till 6v and then charched them again with my Nosram Stealth Evolution-charger.
But I did this also with (through) the balancer atached.
I might try without it.
Also, maybe I could try to descharche and charge the two cells apart. I'll look into the manual of my charger how I could do this regarding the settings i should use.
Also, I guess I could try with a different charger?

I cant belive that some people stick a LiPo in for afew runs and then immediately dismiss it cos their car handles differently???

Wow..

Well Cris, I bought the Lipo for differing reasons, than weight saving and performance...

But my 3200 pack was half the weight of normal NIMH's so the handling would be quite different. After driving the car on NIMH for about 3 years now, it could be hard to go back!

Just my thoughts.

Stick with it Mark.
If things go the way of LiPo in 10th offroad at the next EGM you'll have tonnes of experience over the competion! lol

I cant believe roger is running more than -30% on his throttle exponential and wants the car to feel softer

Does you thumb occasionally spasm or something.

I run mine 0% (linear) its there if i want it, and i never have the car sliding about, its all about discipline

Lee, I said I don't want to go more than 30% ..... I actually prefer it as near linear as possible but with modern NiMhs and silly torquey brushless motors I am struggling to adapt after 3 years away racing noisy smelly things!!!

Got a tip today from Novak on how to soften the response down so going to try that.


Chris, the cars have been designed with a certain weight distribution and loosing weight from the cells seems to upset that from the testing I have done so far (although I will admit it's not a huge amount). On all my cars I am trying to get weight over the front axle ...... not remove it with lighter cells!

I'm not anti lipo at all, I say good luck to those that want to run them .... they are just the opposite of what I am looking for power delivery wise. They would have been awesome back in the days of stock racing though!

Dont keep it a secret Rog

What LiPo do you recommend? I am considering to buy the Trakpower 4900 25C, other choices might be the CORE by Schumacher (CS Electronic in Germany) or the new Robitronic 5200, which seems to behave a little odd when charging is (nearly) complete... Or should I stick to the Orion 3600 carbon? Or are there any others worth considering? thanks!

In 2wd at least the cells are pretty much at the CG of most good cars, so reducing the weight won't change the balance.A lighter car will always be faster overall, you just need to change the setup accordingly

I had a go with a Lipo at Southport recently in the B4 with a 6.5 and no added weight, it was quite rapid but if you behaved yourself it was fine

I can't wait for Lipo to become legal, better performance, less cell voodoo, cheaper, last longer, less stress on everything, whats not to like

i would of had a go with one yesterday at batley..... but i broke my car

[LEGEND]

My friend James Shanley had a go with one once it was the trackpower one. With a 3.5R sintered it was popping wheelies on the slippy. It was hillarious.

[Richard Lowe]

Was that on a York club night? You couldn't hear the other cars over the sound of the poor diff squealing in pain

i tested my maxamps 5500 lipo at batley a few weeks ago in my b44 and it was rapid and handled great when you played nice and didn't go crazy with throttle although it very fun hehe
