The Touota Prius has a 200v, 250A-max Ni-MH battery. The battery
recharges from the electric motor-generator that is powered by the
1500cc gas engine or from braking the already-moving vehicle.

I have a couple alternator companies quoting a 48 volt alternator

batteries in series in a bed mounted battery box with a custom
remote mounted amp. I¡¯ll build up a couple 50V amplifier modules.
I think the CBer¡¯s are right, just add an electrical system for
what you think you need¡ Maybe I can get away from the 750MCM
battery cables that way¡..

Will,
Thanks for the input.
After reading all the post on this subject I will finish the power
supply as follows:
8 x 2 volt 230 Ah cells feeding the amplifier stack
16 volt 3 stage charger, input voltage 230 V AC
12 VDC => 230 VAC sine wave inverter to supply a limited 230 AC for
the charger while driving
an external 230 VAC connector on my trailer hitch so I can charge
the batteries when the car is on the driveway
A better alternative would be to install a second 16 volt DC
alternator, but there is simply no space for a second alternator.
Cheers, Dick

It's kind of funny watching the thread about the mobile
amplifiers
and
voltage requirements.
##### I have zero experience with it. I was just waiting for
you
to come out of the wood work.... since I knew you guys had this
down
pat... and was all old news. The deep cycle communications
batteries work pretty good.
Right now, they're running those yellow top batteries with the spiral
cells. They claim these to be the best. Also, there's really no limit
to the batteries that you parallel together to get the power required
you need. The more batteries, the longer you can run. I've seen the
big 24V batteries used in diesel rigs too ran in these set ups. The
ones you want have the largest amp-hour ratings.
### I also read in an old QST... where they would use 2 x
batteries in series.... like those used in golf carts..... but one
was 6 V... and the other was 8 V. [didn't even know u could get
deep cycle batteries... big ones... in 6 + 8 V ] Then ur car
regulator would charge em to 14 .3 V..... then with engine OFF....
ur small 706-mk-2-G would last way longer. That setup was also
used in some Field day event's.
They use a charging system consisting of a 24 volt alternator,
and
run
parallel / series combos of standard car batteries (or standard
and deep
cycle, if they are smart) to have a 24 volt electric system.
One
alternator, and a pair of batteries will power quite a large
system, as
### Don't some of em use train alternator's ??? Think they
were split stator, dual rotor.... or split rotor, dual stator...
made by Neville Leece.... at 1000 A per stator ?? Or was this
for the tube setups ??
They'll use like 6 of the Leece Neville alternators under the hood to
power the big solid state amps. Some have used generators that can
provide 115/230 Vac too ran off the belt.
### I still haven't seen any detailed website on this hi power
mobile stuff. Trying to generate the power is a huge project in
itself. RFI, etc... Rf decks... is another issue. You are
right... hams are just trying to reinvent the wheel.
Right, not a lot has been published on this as it was all done sort
of under the table away from the FCC.
