As far as assembly of the cells they are no better than most other packs. They do not use double sided tape to hold the cells together, and they only have one layer of shrink on the narrow sides. Tabs are crimp/welded together. The lack of matched cells is a definate assembly issue to me.

As far as customer satisfaction goes, if you have nothing to compare MA packs to except cheap stick packs you will be blow away by the performance. It is hard to say that they are the best when you have no comparision (I had to quit going to nitrokillers cause everyone there was Ma biased with no basis for their claims)

Maxamp with Tekno neu ?
 
Hey I've been reading post over many rc site trying to find the good setup for me. I need to be pretty sure of what I'm buying before doing so because I can't afford to make a mistake and waste 200$+ on battery or any other part I update on my e-revo. Brushless update cost so much!

I finally decided to order the tekno neu 1515 1y squared I'm gonna use with the MMM I got some months ago (wish it will hold down it's V1) and never used.

Now I'm looking for the right lipo to go with my kit. I've seen many and am pretty lost with all the post read. Here's the pack I am wondering about:

MA (yeah I know) 3s 5250Mah 30c x2 for 22.2v - about 350 they told me I could get 15% discount

Neu energy 3s 4900mah 25c x2 for 22.2v about the same price

A123 cell 4s 2300mah x2 in 4s2p setup with a 3rd pack of 3s2p for a total of 7s2p 23.1v 4600mah 30c. About 400$

I've been using home made a123 5s1p in my e-revo for some time and they miss a little punch, but that might be my soldering being pretty bad! ;) I heard well made pack have a lot of power.

Any of you have comments on my ideas, or other pack to recommend. Is the MA good even if they don't stand their claimed C rating or should I go with something else ? I don't want to hijack the trade but u seems to know what u're talking about in here!

Thanks for your help!

you could get Zippy lipos which perform better than MAs for half the price, my suggestion is to run a 1515/2.5d or 1.5y with either 6s lipo or 7s A123 and gear it for 40-45 mph

bensf 01.16.2009 08:43 PM

Get the Neu packs. I've had good luck with teh True RC 8k packs if you want a cheaper alternative. They are pretty heavy though.

suicideneil 01.16.2009 09:16 PM

5s1p is far from ideal for an MT, you need a 2p setup if you want that 'punch' factor, plus Castle state you have to run a 2p setup with their MMM escs otherwise the ripple currents from the cells dropping their voltage under load may cause damage- warrenty wont be honored.

Given the nature of the thread, I wouldnt even concider MA lipos with a 50% discount on price- go for the NeuEnergy, Zippies, Mikes new lipos in the RCM store, or the Elite 35c cells that have had good reviews.

lincpimp 01.16.2009 09:36 PM

Ok, the 1515 1y on 6s lipo is a bit much, you may have issues getting the gearing right. I would suggest 5s lipo, around 5000mah and at least 25c rating. Neuenergy, flightpower, and polyquest all offer packs like that. You could try the elite cells, but I have no experience with them. The 1515 1y will need a good lipo to perform, but you should be able to get the right pack for less than 350.

This is what I would run: http://www.hobbycity.com/hobbycity/s..._5S_25C_Lipoly

Or the similar pack from neuenergy or flightpower.

Wow!!!
 
WOW guys nice disccussion going on here about the Lipos. There are plenty of good competitive batteries on the market now, and it seems that there is not a lot of love here for MA Lipo packs. Experiences seem to vary, but they are still selling them anyway. I personally think we should all boycot Lipo sales until they drop the prices for us. When you think about exactly what is put into these cells, and how much it really costs them to make them, we are truly getting ripped off. The Lipo technology is no longer all the rave and the prices should have dropped way down by now. It looks like they are compensating for the poor economy by keeping the prices sky high. It seems the more we feed them, the more they take from us. The only company that really seems to be continuing its research and improvements is A123 since they are constantly working on the LIon technology for 1/1 cars. I have some Maxamps packs that are OK, but have held off on purchasing any others waiting for things to calm down somewhat in the price ranges. These companies are getting rich leaching off of us. Just my thoughts on the matter.

I've spent too much money on Maxamps to care about their new cells. I puffed a 2s 6k pack in my Rustler with a MM 5700 (and it wasn't overgeared). My 3s pack is soft after use, but still works OK after ~100 cycles. Before I knew better than to buy Maxamps, I bought 2 2s 8k packs at ~$190/ea. for my larger RCs. They still work and seem to be holding up well under my 80mm MedUsa and have somewhere between 100 and 200 cycles. When I found Zippy 5k packs for nearly half the price and experienced how much better they were I really kicked myself for wasting nearly $400 on MA packs.

CORRECTION: I paid OVER $200 per pack because I got the 3 year warranty and the "hard case" option. Warranty was a good choice, but their case is terrible, just a little plastic thing that only covers the top, bottom, and the smaller front sides. I thought it would completely enclose the pack, but the sides of mine have been chewed up a little and there is obviously no protection on the sides.

While we are at it lets boycott clothes aswell. You know hoe cheap those are to make. . .

JERRY2KONE 01.16.2009 10:23 PM

Shopping???
 
I guess when you think about it, it is all about the shopping choices you make. If you want good clothes then you shop at the top end stores and you pay more for what you get. If you want cheap, then you shop at Wal-Mart and you get what you pay for.

The problem I have is that if you buy the Maxamp packs you are paying top dollar, but what are you getting for your money?? It seems to me that there are better more reliable choices out there for your money and you can save on the initial sale price as well. So shop wisely.

Nah just boycott resellers, who have unreasonable mark ups. Why buy $90 Sketcher shoes at foot locker when you can get them at famous footwear for $35. Same as chinese lipos $150 from max amps or $50 from hobby city. ....I say buy the Neus, never had a puff, or problem. My maxamps puff every run, still use them in my crappy cars/projects to laugh

Hmmm, If you decide to boycott clothes please do not take any pics or vids that have you in the frame... Thanks!

Imagine how long a small bottle of tide lasts in a nudist colony...food for thought there. And they can have much larger bedrooms as the closet space can be next to nothing, more living area for the buck! But cold days have to suck, and so do gnats.

suicideneil 01.16.2009 11:21 PM

With all the money they saved not buying clothes, they can afford to crank the heating up. Outside however, they might have to invest in lots of patio heaters...

What would the gnats be sucking exactly?

All this talk about nudist got me thinking,thanks.When I was younger I had a buddy who lived on Maui.I went out there to visit and ended up going to a family birthday party on the beach,actually it's called Makena little beach,with some people he knew.Who just happened to be nudist.So to make a long story short it took me years to get the picture of 2 grown men running around naked ,smearing cake on each other,in front of there kids,wives and parents,out of my mind.Those memorys have now resurfaced. Thanks,thanks alot :(
