I initially wanted to just run single 3s batteries in this setup as I really am not looking for back flipping power. The possibility of running the 3s in parallel will be there only if I really need the extra amperage, which is what I am unsure of.

In the previous post I meant running a single 3s or 4s battery; or running a pair of 2s batteries in series.

I would just run something like a 3S2P 8000mah pack. Your setup is pretty similar to what I was planning on running. MM, 2 speed, mech. brakes, and a 7XL instead of the Medusa. If I remember right I ran it once or twice and it was quite powerful. I used a TrueRC 3S2P 8000mah pack and no BEC and it was pretty quick. Its sat quite a while and I'm about to get some more stuff to finish it up so I'll know more soon. I might go 4S though. Still not sure, much like you, but I have 2 3S packs so what the hell...

Hmm, this is a slayer right?

I currently run a slayer with a hacker 13l (1800kv) on 5s geared for 50mph. A 3700 25c 5s lipo does fine. I run buggy wheels with badlands tires. This truck really does not load the motor very hard, and the quark 125b barely gets warm...

I would say the 3100kv motor on 3s would be fine, but geat a pair of 3000mah or so packs to run in parallel, or a single polyquest 6000 3s 25c pack (my choice). I am guessing a MM will keep up, but an external bec, fan and addl capacitor are mandatory.

I'm curious what the amp draw will be? Wither or not I will have to run batteries in parallel to increase the discharge amperage. I would prefer to just run single packs.

I know this slayer has to be much lighter than a revo.....less plastic and much smaller tires/rims. So I would imagine this setup wouldn't need to be overkill.
