5s lipo you mean?

I would suggest the SPC lipos, or Zippy lipos from hobby city if you are after something similar to the TrueRc lipos.

Bear in mind though, 8000mah packs are made from 2x 4000mah packs in parallel, so a 5s 8000mah lipo will be absolutely huge; I'd say look at a quality 5s 5000mah pack, which really leaves you with Zippy or Neu Energy:

how exactly do you plan to run 5s on a Mama max?

suicideneil 12.25.2008 10:21 PM

Better yet, look at mine and Jordan's builds for a visual reference; I use 2x 5s 4000mah zippy lipos on my truck, he uses 2x 5s 5000mah neu energy lipos- they take up both sides of the gorillamaxx chassis, so you wont fit them on a conversion terribly easily...

electric 12.25.2008 10:26 PM

iv got two 2c lipo 4000mah they are for another car can u explain running in parallel and will probably change to neu energy but for now got to have something, need something for this weekned having a practice race at local track
Thanks for help, wil

S = series, the number of cells wired in series.
C = continuous discharge rating, a multiple of the capacity in amps.

Parallel doubles the mah, and keeps the voltage the same, therefore you get double the run time, but also double the weight and size of battery onboard the truck.

If you want to convert a revo, you wont be able to use an MM unless its a rather old one, and even then, its dodgy to run it as 5s when its rated for 3s, or 4s with some mods.

I'd say for best results stick to a 4s 15c 8000mah lipo fomr SPC, or a 4s 20-30c 5000mah lipo from hobbycity; the 1515 1y will be fine on 4s lipo, 5s will be too much for racing (I think many places put a 4s limit on you anyway?).

how well is the run time looking for at least 20min if can't get that might sell both and buy two monster maxs

electric 12.25.2008 10:50 PM

and how do i connect them together pic would help alot

Andrew32 12.25.2008 10:55 PM

hold on...we need to clear things up...

a 2c battery are some of the largest PIECES OF CRAP IN THE WORLD FOR RC.

now if you mean 2s...thats another story

electric 12.25.2008 10:58 PM

2 cell lipo

haha ok. then thats 2s lipo.

The mamba max is a 3s MAX, 4s if you do the BEC mod.

electric 12.25.2008 11:01 PM

i have that mod and need instruction on how to hook them up and run in parallel

electric 12.26.2008 11:56 AM

hello

jayjay283 12.26.2008 12:11 PM

all you need is this LINK just plug the 2 lipos on the dual end and the single end to the ESC and you are good to go.... but that would make your 2s 4000's into a 2s 8000. If you want a 4s 4000 you need to series them with this LINK
