Lipo battery alternatives?

Hi guys

I've currently got Hpi plazma 5300 7.4 30c x2

Looking to get another 2 any suggestions of same spec but slightly cheaper versions?

Cheers !

If you are just looking for casual use, then I would recommend the 40C Turnigy softpacks from Hobbyking.

 

I have a few of them, and they have been good. 5000Mah 40C packs....

Sounds more like it, will there be much difference in power ?

Yup, turnigy from hobbyking. I use 2x6600 in my 1/8 monster truck

Sounds like where I should be looking!

So electric is new to me ,

So is the plazma I have a 3s?

And what will 6600 give me a 5300 won't?

Sorry if that sounds silly probably does!

And what does the 30c 20c all stand for?

Appreciate it guys!

hobbyking is a good supplier of cheap batteries just make sure you get them from the uk warehouse or there will be a high shipping cost, and take measurements of your battery tray to ensure they will fit.  

No the plazma batteries you have at the moment are 2S (7.4V).

6600mAh is a higher capacity than 5300mAh which will mean a longer run time.

the C rating is the discharge rating of the battery and that combined with the capacity shows how much current it can potentially source. (ie 5300 x 30C is 5.3x30 = 159A)

So in regards to the 30c should I be getting 30c spec to replace ?

If it's lees or more than 30c what will the difference be?

Cheers again

40C will provide a bit more 'oomph' .

The Mah rating tells you how long it should go for. Higher Mah generally means the battery will supply power for longer. C rating tells you how much power there will be in rough terms.

 

If you divide the Mah by 1000 and multiply by the C rating, that tells you the max amps the battery will supply. You want this to be higher than your ESC can handle or your motor demand....then you know your batteries will not get stressed or overtaxed.

 

A 30C 5000Mah LiPo can provide150A..... 5300Mah 30C can stretch to 159 .....whereas a 5000Mah 40C can give 200A. 

 

6600Mah LiPos will give even more run time .... but check your battery tray! Bigger cells. Hobbyking list the dimensions so you can check that whatever you do choose will fit.

Nice one nitro !

Think I might just invest in the 5000 for now at that price!!

Last thing I need deans connection , noticed they are not?
