ic what you are saying now, yeah makes sense

[Finnster]

out of curiosity, how much were you quoted for the big MA pack?
As already said, the "C" rating can be real BS at times depending on the company as there are no real stds. They are not necc lying, but they may be "optimistic."
The only way to really tell is to see discharge graphs and compare performance, as well as anecdotal reports. If a battery is getting hot during use, its pushed too hard.

If you want 60 mph out of a Muggy, then you are going to need a lot of power. I would plan on 2500-3000W peak or so. For 6S, this means about 120-150A peak. If a batt truely does 125A continous you will be fine. However, 3000W out a 1515 is going to start pushing the motor perhaps, esp on a hot wind like a 1Y. If you don't already have the motor, I may think about a 1521 even so you don't possibly overheat and/or use thegreater TQ to gear up and hit your spd goal. 60mph in a big MT is really really fast.

thanks for all ur superb replys, i feel i am begining to learn... lol

i particually like numbers 6 and 7 (i think they are the same) but i would have to buy a specific charger and balancer for the battery, as they seem to use their own brand. are thunder power related to thunder tiger, because i heard they wernt so great...

[VintageMA]

I highly recommend you check out www.rclipos.com. Good prices and great service and shipping. Use the code poly4me at checkout as a promo code and you will get 10% off your entire order.

If you are going to go for TP cell, make sure you go for the eXtreme V2 cells as they are the newest and highest rated. A 6S 5000mAh pack is $300. With discount above you could get for $270.

TP5000-6SXV

22.2V 6-Cell

726grams

50x45x160mm

$299.99

Honestly I would go for 2 or 3 or 4 or 5. I would not go for 6 or 7 as those are the original eXtreme V1 cells which are not as highly rated.

As far as I know Thunder Power and Thunder Tiger are not related - but I could be wrong. Would want someone else to confirm that one.

[lutach]

On my BPP I went from 6S1P 5000mAh to 5S2P 7700 (2 5S 3850mAh) and 5S2P 9200mAh (2 5S 4600mAh) packs and I enjoy my nice long run times.

options 6 an 7 both weigh 1.3kgs...way too heavy try to keep the weight around 750 grams, and for the price of the 9000mah 6s pack you could get 2 5000mah 6s Flghtpower packs and get more run time between the 2 packs...the heavier the truck is the more it will drain the pack

if i should get a 1521, which one should i get?

1521/1D 2900kv
1521/1.5D 1900kv
1521/1Y 1577kv
1521/2D 1425kv
1521/2.5D 1200kv
1521/1.5Y 1050kv
1521/2.5Y 630kv
1521/3Y 525kv

as you can see, all except the 1D have lower kv ratings, so they will be slower than the 1515/1y. i dont think it will be possible to achieve 60mph with a 1521

The 1521 1Y is popular for 6s, and I don't see why you think you won't achieve 60 mph on a 1521...

BTW, the Zippy-H packs are supposed to be very very good packs at an awesome price. A number of airplane/heli guys claim they are enerland quality, but just not matched like you would get on a Neu, PQ, FP or other pack. They are too new to really know the long term stability of the packs, but for 1/3 the $, its hard to go wrong.

Zippy packs @ Hobby city

Zippy 6S 5000 mah (20C)
4800 25C

Or failing that, go 8S and less amps :)

Sounds like Maxamps is the new Venom of lipos. Higher priced, lower quality, popular with the uninformed. Yeah, I was the one questioning the "hate" of maxamps. Your guys' applications are totally different and uncomparable to mine. Personally, my pack suits my needs so I'm not going to come in here and try to defend them and have this guy spend 550!!!???!! on their battery. Obviously, if you guys can get away with running 1p, then them trying to sell a 2p battery says something about them. Especially when its such a high capacity and they still want to go 2p.

Maxamps lipos have their place, mainly 10th scale 2wd. About the only thing they sell that will work in a MT is the 8000 packs. They get rather heavy, and large, especially over 4s. I had alot of issues with defective cells, 10-12 packs... That alone would steer me away from MA, not to mention the outrageous prices, and"questionable" specs.

A 6s lipo may be too much for the 1515 1y, go with a 1521 motor, 1800-2000kv for 6s...

[glassdoctor]

I love my 12000mah pack LOL!!!!

You gotta see the face of the nitro guys when they hear how long my CRT can run on a charge... good stuff.

But I don't recommend a pack this big. I did it only for runtime.
