2 volt batteries

[civil 0]

So my question is, how many have tried a 12v battery with a 2v battery in series to get 14v and charge at 16.3-16.8 volts... And this would be a daily / spl setup. so let me hear all the pro's @ con's, I think it would rock

Why?

there was a company i forget who, but they made essentially the same thing, it was a dual voltage battery one post for 12 and one post for 14, you charged it via the 14v terminal but ran your cars electronics off the 12v one

Why?

I have little room to work with and xs 14 volt batteries are only 50 ah and cost to much.. I could get more power with 12v 100ah and 2v 100ah in series ..So say i have 4 -12 volt and 4-2 volt this would = 8- 50 ah xs 14 volt batteries.

The issue will be in charging. The battery that ak11667 mentioned may have a 12v tap for the electronics on the car that can't handle the 16+ volts of charge, but all cells inside the battery are the same and the battery as a whole is designed to charge as such. Having a seperate 2v cell that has it's own internal resistance differences and charging properties would probably not charge correctly when paired up with a 12v battery like that.

Why do you need a 14v battery for in the first place? If you're not competing the two extra volts aren't going to make any usable difference for you anyway.

I do compete SS 3-4 14v would make my amps happy... more is better I will give it a try ....

if you compete then oin most classes you can not be over 15.3 volts or so... so there would be a problem with your 144 volt system.. because it charges at 16 volts.

It's illegal in some orgs too.
