Peco sells it's products world-wide. If you demand product 'xyz' they
will sell it to you. It's the importer who decides which of Peco's
products they will stock, based on perceived demand.
I've just gone through the procedure of telling the NZ importer of Peco
that they should stock the G guage range. I buy my HO code 75 from

No, it's not. When you remove the 13.8 volt source, which is NOT the
battery, the battery remains at 12 volts. Period.
No, Greg. If you were to say use 20 volts to charge, that would be
too high a level. There's no way to charge a 12 volt battery to any
old voltage you choose. Even 13.8 volts is impossible. Thus, when
the charge voltage is removed, the battery is at 12 volts. No more
than that or just barely above it. Certainly that battery will never
be charged to 20 volts or even 13.8 volts. You're grasping at straws
Lead-acid batteries are nearly impossible to overcharge but if you
apply to high a float potential you will get gassing or outgassing.
I decided to make it rear wheel drive with the entire front
compartment reserved for batteries. I'm experimenting with the fuel
cells. Two motors on the rear and all the power and most of the mass
up front. Since the mass is all between the axles front to back,
that will make it a very stable vehicle. Small, but stable.
We will just have to agree to differ on that point - all my multimeters
agree with me.
Basic Ohms law here:
Input voltage (minus voltage sources in circuit) / resistance = current
13.8v+ / resistance = excessive current.
That's the voltage my cite claims is possible. Even your cite said 13.2
That doesn't agree with reality.
If the charge level is less than 12 volts you won't find 12 volts across
Just barely above it?? 12.5? 13? 13.2?
13.8 volts is the (safe) limit.
I'm still holding the same straws I started with.
That has to do with resistance/current flow.
I was designing a minimal two in-line seat 4 wheel vehicle to minimise
wind and rolling resistance. Building and certifying such a vehicle
could be a long process.
I now have to start over with an existing vehicle and extrapolate
everything I've done so far.
I still have to get to that, rellies here until an hour ago. However it
has to be something I can obtain here, at a workable cost.
Well Ray, it seems that you haven't ever actually measured a battery
voltage while it is being charged! [And for the few microseconds AFTER
removal of the charging voltage.] The voltage RAPIDLY drops, but there
IS a finite time where the voltage is STILL at the 13.8 volt level.

I've done both. The battery under charge has a floating voltage of
13.8 volts not from the battery but from the charging circuit. After
the charging circuit is removed, the battery is at 12 volts.
Anything else is just plain nonsense.

I know what a zener diode is and what they look like, and I haven't seen
any of them in any wall warts either (and that's *dozens*, not just a
