I have 4 - 6 volt 58 amp battery's. Is there any way to wire them in
series, so I can wire loads of 6v 12v and 24v and wire in a 6 volt
trickle charger to charge them all
Thanks
Rick

Not simultaneously.
I think.
Cheers

Could I not connect the charger parallel to each battery using diodes
somehow

No - but you could use four separate chargers, one connected to each
battery.

Try to draw the circuit. It just won't work. You will need a 24V
trickle charger unless you charge the batteries one at a time.

But using a 24V charger is highly unrecommended in this case, as he is
planning to draw power from the 6v and 12V points in the combined
battery - this will result in the "bottom" two batteries being
under-charged while the "top" two will be overcharged.

I have 2- 12 volt trickle chargers I could put in series.
If I had 2 -12 volt battery's wired in series One fully charged and
the other half drained. Wouldn't the fully charged battery level out
and bring the second one up so both batteries are about the same

Perhaps he could use a step-down Buck converter, and convert the 24V
from the batteries in series down to 6V and 12V?
http://en.wikipedia.org/wiki/Buck_converter
This avoids having some batteries work harder than others...

If you have two 12 volt chargers and put one on each half of the 24
volt bank, then each charger should keep "its own" battery charged.
However, since you also want to get 6 volts out of this system, that
won't keep the two "bottom" batteries balanced.
The best solution would be to connect the batteries as required to
directly supply the highest current load, then use DC-DC converters to
operate from that voltage, and produce the other two voltages. If the
power required at 6 volts is very low (perhaps a few 10's of mA) a
simple linear regulator (such as an LM317) operating from the 12V
supply may be practical.
Since you haven't mentioned what current is required at each voltage,
it is impossible to make any firm recommendations as to the best
solution.

It could probably theoretically be done with 4x isolated wallwarts (and
proper charging circuitry), but it'd probably be a PITA, and there are
always "gotchas" with this sort of thing.
Good Luck!
