Default Whats so good about lipos? ----> Noob

Hi guys,

yes "another noob" who doesent know about lipos. Im asking because I have some "Muchmore" racing saddle pack NIMH 7.2v batteries that are 4500 mah and I've seen the lipos and for example the Trak power lipo saddle pack is only 3800 mah so is the battery i have now better or have i missed something?

sorry, i know questions like these have been asked before

they give more power out, the voltage drops less and you can charge and store, and not have to do anything to them befor eputting in the car.

Also, they are lighter and they last longer (more charges), have less internal resistance (don't get as hot, and longer runtime compared to NiMH of the same capacity).

But you are right in that the saddle lipos aren't as high capacity as the long brick lipos.

Frankly, saddle pack chassis configurations are designed around heavy (NiMH) batteries and assume that the heaviest(most massive, to be precise) component is the battery pack. They aren't as lipo-friendly as the 6-cell inline chassis in some ways.

A more simple answer would be to the question 'What is bad about going lipo?'

You have to get a new charger.

If you severly damage them they can not only rupture (like nickle batteries) but also catch fire.

You will feel like a fool going, "Why the hell did I wait so long for before buying lipos?"


Now if you treat them with respect and love they will pay you back in spades.

If you over-charge a NiMH cell they can go bang in a pretty cool way, I for one don't like to be near them when it happens tho. While were on the subject, if you stab yourself with a kitchen knife that can be pretty painful

Any thing can be dangerous if not used correctly, follow the instructions and you will be fine

I think a better way to put it would be it does not loose performance though its lifespan.

Where have you got the 100 cycles from? Just curious as I was thinking of getting some too.

I'm not quite sure on that Ash, I know the Trakpower I had 'lent' to me was one of the original one's which had well over 100 cycle was still plenty quick enough, and had no noticeable difference to a new one.

I've also known touring car boys to say NiMH cells go off after 5 runs max

I found that on either modeltech or trakpowers own website, but it also says good for 200 cycles practicing, so I guess it just means there's a chance of performance loss after 100 cycles?

Never got that much out of my nimh anyway!

100 cycles seems awfully low???

We range 300+ cycles on the Core packs, and I know most other LiPo's, if taken care of will last just as long??

You are right Adam. In the short time I have been running the Core RC 5000 packs they have proven themselves to be absolute top of the line. You know I have only had them for about 6 months but I do use the heck out of them. I am also useing them in my 1/8 and larger scale cars. I am going to use 4 of them on my 1/5 Lauterbacher soon.

If you want them to last even longer than 3 to 400 cycles charge them under a liion setting. This will not fully peak out the pack greatly increasing the life of the pack.

Im pronounce Ni-mh as "Nim", or bangers if I am talking about IB4200's :LOL:

Don't forget, to use Lipo at the BRCA it firstly has to pass through the AGM. So members of the BRCA please do attend if you want change. Or, ofcause, if you want to be against the change, you will need to be at the AGM.

as per www.brca.org race calender, 26th October.
