Will I need battery power?

[Full Tilt 10+ year member]

Hey, all. I'm putting together a system that I'll hopefully have running in the next month or two. I was just curious what I was going to have to do for electrical power.

I plan on running a Taramps HD6500, how do I know what to plan for as far as power draw goes?

I just received a 250A H/O alternator from Mike Singer, should I use this and run some batteries or would I be better off opting for a larger one to begin with? If I could make this work, how do I determine:

A) How much battery reserve I'll need,

and

B) How much power wire I'll need?

I'd use at least two big assume batteries.. or a nice capbank. If you can afford it and have the space..

A 250 alt will be fine for the HD 6500. It's not like a Korean 6.5k amp.

I ran a Banda 7k with a 320 amp alt and one XS D3100 battery.

Honestly, you could get away with one big battery in the back and a smaller AGM up front. Lowest my voltage dropped to was 13.1v full tilt. I charged at 15v.

Taramps amplifiers don't like high voltage anyways, so you're fine with the 250 amp alt and one big secondary AGM

depends if you run dedicated runs.. youll need at least 2 large batts imo the more power you have available the more youll get out of that amp

I'd be really interested in a cap bank, primarily for weight savings; where could I go to learn more about them?

The only problem is, they definitely don't like low voltages, either. Did everything hold up and look okay? I'm just concerned about the Brazilian technology and keeping the voltage as steady as possible.

Do you think a dual alt setup with my stocker + the 250 would get me close?

series 5 of those together to get 14 volts. that should be enough cap f to keep voltage sag down. just get you one strong battery up front and put the cap bank in the back by the amp.

More batteries the better, but I don't think you'd need a ton. My Banda 7k was perfectly happy with one XS D3100. That thing's a beast though. A year old and still cranked over 1,000 amps //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
