Default The truth about Lipo brands??

Ok..now that several reputable places offer lower cost lipos compared to the big battery companies, can you honestly tell the difference? Unless I had a pack already heading south, I have never been able to "feel" any difference between a $130 300C pack over a .$50 35C pack. Any others have different experiences? ( I know there isn't any 300C packs...yet..lol)

Depends on what you want and what class you run... In fast classes, such as mod or boosted stock, I don't think there is much performance gain from a better battery. However with pure stock classes, blinky etc., the battery is often crucial to be first (since its the only parameter which you can search for tenths of a second, if ESC and motor are mostly the same), so it makes these slow classes actually pretty expensive. On my track, with my car (10.5T full boost), I don't feel any difference between my 35C packs and my one million C packs, but laptimes tend to show the bigger number packs are slightly faster.

I would disagree to a certain point. I think in mod my car is more responsive with the 100c battery vs the 65c I was running. Starting wise they both felt fairly well but later in the run the 100c felt more responsive. Not granted there was a mah difference but not huge.

In stock I wouldn't use anything but the higher c packs.

Also typically quality control too. There are certain brands that don't use a certain level of cell. So if your paying 30 bucks for a 100c 6500 mah pack it's probably not that great with ir or quality to begin with.

I can say that the SMC lipos have more punch then the best Reedys you can buy. I also let someone borrow a 70C SMC to use for a race in place of a nearly new Revtech 100C, and he said the SMC was more consistent.

I would say that you would have to be a super clean and consistent driver to notice the difference between the mid and higher grade lipos. Personally, I am not gonna buy anything other than SMCs. Danny is a very honest guy, and doesn't sell the packs for full price if they have a higher IR.

hopefully this helps...

this are all brand new 1s packs, straight out of the packaging.

thunder power -
smc-
protoype pack & both above all tested pretty much the same

crc- was just a tiny bit lower on the voltage curve in the beginning then slightly dropped down towards the end. pretty much ended the run time earlier than other three. lap times were about a tenth slower on average

generic pack- was about a tenth or two slower & run time was also shorter than other packs. the drop-off towards the end was a bit significant but was good for a 5 -8 minute race. might be pushing it tho towards the 8 minute mark. i would say club race worthy but definitely not for any big race, this might cost you a possible win

ill post individual side by side comparison later

Default PROTO VS SMC

arguably this is the best bang for the buck for any battery we tested- "IF" your lucky get a good pack...... might be a hit and miss sometimes.

These graphs are meaningless without the X axis and method of testing.

I can draw graphs in excel too.

What if by the end of a 5 minute race you never each the end of the curve??

Default PROTO VS CRC

not much to say here, hopefully this was just a bad batch. that gap between the lines is worth about a tenth of second per lap. on bigger tracks it would be more difference on lap times & less difference on smaller tracks

who said you will reach the end of the curve? this packs are as close as you can possibly get, you will never reach that end on a 5 minute race. if its useless to you, you don't have to look

Default PROTO VS GENERIC

if you don't like what your seeing then this is not for you... we are just sharing data we gathered, if it helps you great if not move on.
on the graph below, the gap between the lines is about a tenth to 2 tenth's & probably only usable for club race.

You're only sharing half the data. You show voltage, but not the time. What does each line in the X axis represent? 1 minute? If so that chart just says don't use a generic 1s or CRC if you run an 8 minute main and you will be ok.

If you wanna go into detail, there are too many other factors to consider before we can even get close to deciding if a certain pack is better than another.

Voltage & Time alone does not say much. Battery A may hold a higher Voltage for a longer time in 17.5 blinky race loads, but battery B could also possibly hold a higher voltage for a longer time than battery A but in Mod loads....

I hope you get what I'm saying...

In other words, the only way to know is through lap times & race results.
