Batcap wiring

[M@nJo 10+ year member]

I am thinking about picking up either the Batcap 800 or 400 to replace my cap. The 400 model looks like it can be wired as if its a capacitor and the 800 model appears more of a car battery. I am running a distro block from my positive battery split into 3 ways (sub amp, speaker amp, cap). My grounding point is split into 3 ways into all 3 sources. So I'm just wanting some confirmation on how to wire it.

If I picked up an Batcap 800, can I run it off the distro block and use the same ground point or will I have to run some 1/0 gauge from the hood battery to rear? Same question for the batcap 400 model.

I'm running optima yellow up front, big-3 done, 70A OEM alt. 1600wrms hifonics watts and 400wrms power acoustik watts...yes overrated stuff

heres a lame diagram of proposed idea:

Either one will be wired the same, and yes, you should probably fuse it in the front and rear both.

If I'm not mistaken...the batcap 800s are cheaper than the 400s brand new, dunno if you're looking at used stuff, but if space isn't an issue, just get the 800

I'm still searching on their website but do the batcap's (specifically the 800 model) release any toxins? What size fuse should I run from batcap to distro block?

nah, they're safe to have in your car.

Fuse size depends on how much power it'll be pulling. Either run by your amplifier rating, or your alternator, whichever is higher. then go a little above that. (if it's 120, run a 150)

it appears that I should be using the positive post of the batcap as a distro block. can i use the same grounding point for it as well?

The Batcap support info says to never ground the Batcap to the chassis. Didn't mean to resurrect a dead thread...I just wanted to put the info out there. Carry on....
