what kind of batteries would you use? Not a deep cycle I hope.

You can also manually hook your batteries all up to 12 volts and then charge them. There are high output alternators made that would have a less likely chance of getting hot and burning out if your batteries are too low.  

After the batteries are brought up, you can then disconnect the lead wire from the alternator and then hook your batteries up in series.  meaning 12-24-36-48 etc.

You should not keep the hot lead connected to your hydraulics in any way.  Yes the first battery in your setup is 12v, but for some reason I have seen the car engine starter stick, really sucks. So don't mix your setup batteries with your cars engine battery.

You don't really want to charge a dead battery/s with your alternator, because the alternator will put out it's maximum volts/amps and get hot. It can put out it's max for a short time, but shouldn't be used like this on a regular basis.

I have also seen 24VDC alternators

You could use this as an additional alternator with brackets and pully and just run the 24volts to your setup if you were using just 24 volts.  24 volts will work good if your setup is done using the hi-torque motor.

You could also use the 24 volt alternator in place of your 12 volt alternator, you would need to set your batteries up to use your cars engine battery along with your one setup battery. This would equal 24 volts.  BUT again you really would not want to include your engine battery within your setup batteries.  

Away around this might be to create a quick disconnect on the possitive side to your starter.

The thing about alternators is that they can put out over 100 volts DC.  Remember it's the voltage regulator keeping the volts to the battery at around 14 volts.

Alternators are rated in AMPS, 35, 60, 80, 110 etc.  Amps is what you are looking for, meaning it potentially can put out lots of charging power

Keeping this in mind, you get a custom voltage regulator, but again you don't want the alternator running at or near maximum output for too long, Using the high output alternators should be considered if you plan on going this way.


You might be able to use the old style mechanical volts regulators and tweak the contact tension to  create 24 volts(or more).
