16v daily?

[JEXTEL 10+ year member]

well it comes a time in ever young mans life that he notice more power can be made with more voltage..lol

But really my idea is this:

get an alternator and Ext. Reg., get a PM step down box, and get 4 16v batteries for the trunk

my questions are can GP3000d's take 16+ volts daily? i've been reading some amps take it better than others? I know my gp3kds are unregulator so I know taking the power is not the problem. The problem is can they take that kind of power daily?

Also what is the whole story about step down boxes being spiky? and not having longevity?

and lasty..do you think 4 16v batteries can handle 4 gp3000ds daily?

You will need several step-downs to really run a 12v system, especially since you have those multi-channel amps... I'd say four or five would do nicely.

It will work great ,i would get atleast 8 batts ...if you have the room /and the funds

Why so many step down boxes?

I thought i had to run 2 wires from the alternator(1 to the 16v bank and the other to 12v battery in the front)

then inbetween the wire from the alt to the 12v battery in the front? with the PM step i can go as high as 19v for charging because of the 3.6v step-down(i know that equals 15.4v i have 15.6v on my batteries now from the MLA module)

how is the 3 post battery step working for you?

Because they are rated at 50a MAX. You will need one stepdown per 50a of 12v current you need.

50A is also peak... its in the 20s for continuous operation. So more is a good idea for sure if you have a decent 12v load.

if you go 16v's a batcap 8400 gives you the biggest bang for the buck

gp3000d's can take 16v no problem

high voltage protection kicks in around 18.4-18.5 volts.

i'm running dual post batteries, but i just recently learned that all 12v posts must be connected as well as 16v posts... The 1 with the 12v draw i had balooned, but again, that was because it was the only 1 out of the 5 with the 12v draw.

What are some good step down modules to use?

 

[JEXTEL 10+ year member]

****..is the 3 post battery decent?

if i go the 3 post battery route ill have a bank of 12v and 16v batteries..

hmm..what to do..

and im not fully understanding the step down boxes..20a per 12v?

dont get the 3 post 16v

Possibly use the Harrison Labs flux caps? They turn your stock electrical into 18v+ into the back bank.

Or do a 'separate' electrical system for 16V

dont get the 3 post 16v

troof lol
