Word... I'm liking my Hyperion lipo more and more each day.

MindThoughts

I see your point. Even if the Drag Racers in the you tube video are using three- 4cell LiPo's run in parallel(14.8volts total voltage- combined)- at 676grams each- times three = just under five pounds. It may not be worth the 220.oo dollars times three = 660.oo dollars to have a five pound battery- rather than a battery that weighs much more than that- in the Lead Acid Chemistries. But then again- some racers are willing to pay allot of money to save a few pounds. And a 12 or 16volt Lead Acid Battery Can Sure Get Quite Heavy. What would a lead acid Drag Race Battery Weigh? 30+ Pounds? I didn't see any specifications of battery weights for 12v or 16v Drag Race Batteries.

PS. I sure like the sound of those Dragsters :)

Note: It seems the single Turnigy LiPo Starting the automobile engine- was certainly quite impressive- to say the least :)

Im glad you didnt take that personally, but you have to keep your objective cap on your head when viewing seemingly impressive vids like that- little bit of research shows/showed it to be far from impressive..

MindThoughts · **An Objective Viewpoint vs A Subjective Experience. -** 12.02.2010, 10:03 PM

Thank you,
I certainly appreciate you looking out for me :)

PS. The amount of knowledge and technical ability of many of the RCMonster forum members is absolutely awesome- and it's always great to see the technical formulas- and mathematical brilliance that so often sheds light onto any given subject. It's great to express opinions with passionate emotion- but to me- nothing is more powerful than raw data and like many brilliant minds here on this thread have said- the numbers are hard to argue with. That said- it would also be great if someone was able to compare these MaxAmps LiPo's to any other- or many other model LiPo's from different companies.

Note:
I realize it upsets people to see "True 150amp"(which represents a 1 second burst- ability) on the front of this model LiPo but the main thing that I would like to see is- How do these LiPo's compare to the other high end batteries in the RC Industry- ie Hyperion- Thunder Power- Turnigy(I'm beginning to consider Turnigy a high end- low cost battery)- and any other LiPo anyone would like to throw in the mix. It's the comparative data that really is the valuable information(I see no reason MaxAmps cannot perform these comparative test). Until the RC Industry has a standard by which all LiPo's must be measured- there's no basis for rules to play by- or at least seeming so.

Might want to take a look at the BigSquidRC 4S Shootout for a graph of the Turnigy's...

Costs. No one will believe them. An independent body would be the best way to do it. But again it goes back to cost.

MindThoughts · **BigSquidRC LiPo Shootout. -** 12.03.2010, 01:27 AM

This was an excellent review to read- Thank you for metioning it :)
I primarily run one- 3cell LiPo in my 1/8th scale buggy- Can you recommend a review of different 3cell LiPo's? I'll Look into the same site to see if I find anything BigSquidRC may have done- insofar as testing different 3cell LiPo Batteries and comparing the different related data.

PS. I wonder why MaxAmps didn't participate in this shootout? After all, MaxAmps makes a LiPo which is a hard case 4cell- which qualifies the MaxAmps batteries for this shootout.

I'll write BigSquid and ask them why they didn't include MaxAmps in the shootout. If anyone already knows- please feel free to mention your insight into this matter.

Where is that? All i could find were the Lipo tests 1 and 2
EDIT: found it

Well guys I just got a netbook tonight. As soon as I can get the software for my EagleTree on here I will do a run with my NeuEnergy 4s Lipo and we can compare them. The 4s 5500mah Neu was about $120, and claims 25/50C. If someone wants to send me a MA lipo I will run the same test!

MindThoughts · **Eagle Tree Telemetry System. -** 12.03.2010, 01:18 AM

Which model Eagle Tree Telemetry System Are You Using? I'm also interested in buying one of these to help with setup and testing- but was not sure which AMP rating(Model) to purchase for use with 1/8th scale systems. Which model do you recommend?

I don't know what they have to offer now but when I bought mine I got the 150Amp version as it was the highest they had

I've got the 100 Amp version but it's handled spikes up to 130 amps fine.

MindThoughts · **Eagle Tree Telemetry Systems. -** 12.03.2010, 02:52 AM

Awesome- Thank you.

Note: Someone had mention to me- that own and uses the 150amp veriety of Eagle Tree Telemetry System- that he wish he had bought the 100amp version because the 150amp does not have the same resolution for the area of amps that he's actually using. I didn't really understand what he meant by that. I thought it seem quite a good idea to buy the 150amp version because this way I would record any amp draw- acceration spikes up to 150amps- which I do not imagine I would exceed. Especially being that I run a 1/10th scale motor (1409 1Y 3600kv Neu on one three cell TP 40c LiPo) in my 1/8th scale Hyper 9E buggy. And it's absolutely crazy fast.

I'm considering buying the 100amp version. My concern was that if I spiked anything over 100amps for any length of time such as a few seconds while wide open- acceleration- my concern was that the Telemetry System would not read that data. But if your system is the 100amp and it's reading spikes up to 130amps- sounds like this could very well be the ideal system for me to use with my system. Thank you :)

So i just scanned over the 4s shootout, and i have to say it was kind of lame. First off i will say i am a big fan of cheap, so to say i am a Turnigy fanboy is pretty accurate. Why did they choose the 4500 turnigy as opposed to one more comparable to the size of the others? Also the turnigy had the second to lowest C rating and that coupled with the least amount of capacity will give it less voltage under load than the others.....DUH. BUT....the voltage was only like, what, a fifth of a volt less than the highest rated pack? And it was probably due to the fact of the capacity and C rating.

Regardless I will still buy cheap, the price difference between the turnigy and the others was HUGE! Now we just need to see a test of the Nano-Tech's

MindThoughts · 06:02 AM

My thoughts exactly. And the fact that they say- just look at the charts- The charts show everything- was kinda funny because upon looking back at the charts I saw the same thing I saw the first time I read the entire review- That the Turnigy- taking into consideration the details you took into account- are actually totally awesome and right up there with the best of the best- Yet at a very small fraction of the cost. I will say this- for the past year- Hobby King batteries- and Specifically the Turnigy Line of LiPo cells- has become extreemly popular at the tracks. People want what the Pros have, but most will buy what they can afford. And many racers are buying the Turnigy cells to practice with and club race with as well- and often will race the big series races with the more expensive batteries- but one might begin to ask themselves- Why not always run the $40.oo dollar LiPo rather than the 200.oo dollar LiPo. I'm at the point in time where I'm ready to buy my first Turnigy cells- just out of curiosity.

You'd be surprised how much current you can pull! In my truggy on 5s geared for about 38MPH I had peaks over 160Amps. These MA packs should do great at those current levels, according to the label!!! However I don't beleive their labels as I severely puffed a 5s 5000mah pack in that truck after I lowered the gearing
