Lipo options

[russruss123]

Ok so I'm looking to get some lipos to bash with my sct 4x4.

Esc is 120a

I want long run times but wanna have some fast fun. 

 

Looking at these

Or

Am I right in thinking the constant 90c will get me shorter run times. 

I know that they have bigger mah. 

Think the first ones will have more top speed

Was gonna get two of whichever as I already have 2 of these

Also to work out that the battery's have enough amps for esc is it mah\1000x c rating. Sure I read this somewhere I while ago.

Discharge (C) is like the grade of the fuel, but has no effect on run time, Mah is how much fuel you have.

 

so more MAh will last longer no matter the C rating but will be heavier and if racing that would effect handling, and speed / acceleration.(For a basher you wont notice but Im a flyer (Quads) so every G matter to me)

 

A higher C will allow the battery to sag less underload and generally perform better, more punchy, however if a 30C battery can provide more amps than the motor will every draw there is little point in going to a higher C. (Higher C counts cost more and are more waight)

 

You are right in that there is a calc to work out a batterys amp's, so you will find a 40C 3000mah battery would actually have less amps than a 15C 10K battery so larger batteries you can drop the C rateing to what might sound low but really isnt...you need to calculate this though to work out what C you need, although factor in that most MFGs fudge these ratings anyways...so its best to get the best you can afford. 

 

Use this to work the above out = http://www.kritikalmass.net/battery-calculator/

 

Also don't forget to check that the batteries fit your battery tray, and lastly, those batteries linked look like they are 2S, I dont have a sct 4x4 but it looks like it can handle a 3S so you'd get more speed by going that way than a higher C 2S, although I could be wrong in that it takes a 3S so make sure you cheack that, tbh though your battery linked are very well specced, if your not racing do you need that higher of a C rateing when you could save money on a cheaper pack?

TDLR - The 7500 is double the price nearly for only an extra 1500mah. so you might as well get two of the cheaper ones, they are still very high C rating...if it was me id grab the 6000mah ones.

Thanks guys. 

I believe my esc can take up to 4s but not sure about the drivetrain. 

 

I already have a pair of 3s 6400mah I'll give them a whirl aswell. 

But yh it does look like the cheaper ones will give me better value for money. 

 

Also there are some nano techs even cheaper but I like the hard case packs
