I'm looking for a battery to provide some stored juice for my US Amps 4000x. I have an 220amp alternator comming soon, and now i'm trying to decide which battery to buy.

Stinger sp1700 (1700amp for 5 seconds)

Batcap 8400 (9600amps ???)

I'm skeptical of the stingers performance, I have a stinger 1f cap and it doesn't do anything. Does anyone have personal experience with the sp1700?

The batcap seems like overkill, but I would prefer to have too much power rather then not enough

Can anyone suggest other batteries with high output?

 

what class? are u allowed to have 16v set up? if u are i'd go for batcap, if not stinger/hawker is the battery to get. i have two in my jeep and loving them.

 

I'm just planning on keeping reserve current for burps at steady 14v if possible As I don't think the 4000x will take 16 or 17volts

 

How about a Batcap 800? Has anyone used this product before?

 

dude what class? it all depends. bat caps are not allowed in street and street max class.

 

It will prolly be SS1-2

 

battcap

 

So for a daily driver that doesn't compete which would be better? Batcap or a second battery?
