14v/16v battery

[Tarball]

As the title says. I've been doing some research on 16v electrical systems as I am designing my system. Currently I will be going with alt set to charge 16v battery bank and step downs to the vehicles electrical system.

I know there are 16/12v batteries (with the dual ++ terminal) to feed the 12v to the cars electric. My question is why not a 16/14v battery since the vehicles electrical system really wants to see 14.x volts while running.

From the designing side of things it seems like a no-brainer and there should be a product available for this.

I'm already invested in Step-Downs for my application but someone help me to understand why the 16/12v battery exists and why 16/14v does not. 16/14 just seems more practical.

Discuss...

because a 14v battery charges at 16v and sits at 14v

a 12v battery charges at 14v and sits at 12v

so if you ran most cars on a 14v battery at 16v you would have VERY strong chance of frying your computer and wiring in your car

so you will be running your amp at 18 volts. Are you doing this for daily? If so be careful i have heard people say they have had no problem doing it. Then the other side says not to or they dont recommend running it for a long period of time because its hard on the amp.

Rob hit the nail on the head... if your going to run 16v then just put a 16/12 under the hood and build your bank with 16v's I hear that the cars electrical like the 12v side of the 16/12s cause of the more constant power flow someone on here I think it was Don said he gained some mpgs after running the 16/12.

A 16v rest around 17.4-17.7 will drop 16.xV under load sundown amp amongst other can handle that daily

yeah that is one and there are a couple more. But i just dont think i would run a amp daily to long on 18v its just hard on amps.

May you misunderstand what I mean. Or perhaps its something I dont understand.

Take a 16/12v battery for example.

Car running charging through the 16v post around 18v. What is the 12v side putting out? 12v or 14ish ?
