does anyone use really big batteries?

[ReV:-O]

hi there,
im gonna buy a losi muggy with a MMM esc and a Neu 1515/1y motor.
I was gonna buy a coule of Maxamps 3s2p 8000mAh 20C lipo's for it, but after speaking to someone at maxamps, he told me to get them to make me a custom pack - a 6s2p 8400mAh 25C lipo to be precise. He told me to get this because the muggy will be heavy and the Neu might have to work extra hard and pull more amps. he said getting this battery will make everything run cooler and provide the amps the motor might need.

BUT this pack is huge! it weighs around 1320g and is 98mm tall! I am just curious, if this pack really is so great, why havent i seen anyone else with big packs?

thanks

or you could just get a better brand battery and not worry about it. You do not need up to 2p for the 1y I run a single 5s made by flight power on my 1y in a very very heavy savage and no problems at all.

big= heavy, hard to secure in truck
go fo 5000mah ones

[bdebde]

A 6s1p 5000mah 25c - 30c would be plenty. I use Neu 6s 4300 25c with 1515 2.5D motor; 20 - 25 min run time. The 1Y will pull a few more amps, but 5000mah high quality batts should be fine.

nah, im afraid its 8000mAh minimum for me! im looking for at LEAST 45 minutes of bashing time lol

[bl-is-future]

i get 45 with my 5000mah longer if i am just tooling around

[wallot]

get two packs. truck will be lighter so there will ne less strain on drivetrain and changing packs matter of minute

[ReV:-O]

two packs still works out to be about 1kg, and with the muggy they would both have to be on the same side

[bl-is-future]

no he means run one pack then when that one depleats put the other one in. And like i said i get 45 or more with my 5000mah

[ReV:-O]

but how can i get 6s with one pack other than a heavy custom made one?

[bl-is-future]

it is not the 6s that is the issue it is the 2p part.
You can get a better brand battery and run only a 6s1p on 5000mah and size will be good and so will run time.

oh right. i get you now. thats a decent battery but its not much good with the Neu, because it is only 125A continuous. The Neu is 120A continuous and could have bursts of at least 150A. I think thats why the Maxamps guy reccommended i got a 200A continuous battery

[bl-is-future]

You are missing the point. MAXAMPs lipos are a waste of money IMO. the guy told you needed that much in a maxamps batt because they do not deliver like other batts hence the FP one i linked. If you get a BETTER battery that much is not needed. I run a FP 5000mah 5s with a 15151y made by NEU and it does not puff or work the battery at all. I ran the same setup with a 5s maxamps 5000mah and it puffed and overheated and was junk. Do you get what i am saying now?

[ReV:-O]

yeah kinda, but how comes so many people use maxamps if they are not very good?
i thought they were the most popular brand. so flightpower you say? do they make any 8000mAh batteries do you know? or at least 160A continuous batteries just to be safe. 125A is too close to 120A for my liking, even if you say it works (no offence, im just paranoid lol)

[bl-is-future]

if you read not many people do use maxamps. Put in the search bar on this forum on maxamps and you will find there are very few that run them and like them.
im telling you it will work fine.
