Is Maxamps any better now?

Maybe someone on here knows.How did the c ratings come to be used as the standard?Why do they not just use amps?I think it would make our lives so much easier if they said ,100amps constant for 5000mah,before hitting a 3.2volt cutoff.

I believe this is because they want us to understand a couple of things.

Amperage output is affected by capacity for a given "class" or C rating.

A 20C 4000mah pack will put out 80 amps continous where as a 10C pack will put out half of that. You can play with the numbers but the formula remains the same.

To obtain a higher C rating, manufacturers use a greater anode/cathode material to Electrolyte ratio. This is why the higher the c rating, the more they weigh for the same capacity.

It's the use of more Anode/Cathode material in the higher C cells that increases the cost.

I believe most manufacturers don't falsely rate their cells. This is their reputation. But............then the product gets passed to the retailer. It then gets "labeled".

I can just imagine some thoughts like:

Most users won't push these that hard anyway.

The RC Electric setups on the market can't handle more than these put out.

If we charge more, the added profits will cover warranty claims for those that do push them. It's only gonna be a small percentage, plus we can blame it on their setup and suggest larger more expensive packs that we carry. More Sales! It's a win-win.

In the beginning of the "transition" from Nimh to Lipo in the RC Industry, I believe this was pretty easy to get away with.

It's getting tougher, as the market competition increases. The average prices are dropping and the cells are getting better.

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
