27 volts at the base. DC has very little loss over 400-500 foot
distances. We are seeing about .1 volt loss on a 400 foot run.

That depends on wire size. That distance is not going to be ethernet
so I will assume #12 AWG, 400ft, copper wire, etc. You should be
seeing a 5.6% drop under a 1amp load or about 25v under load.

We see 27.3 volts at the battery. And 27.1 volts at the top with no
load.
Obviously load will have an impact on this.

Hi Cameron and All
thank you for the hint.. What about worldpay?
By the way I am not sure if the PCI-DSS certification would be a way to
go or better to stay without it till the volume/month will be more than
10K/month.
Comments in this last statement?

U mean the Charge current is 27-28V.for 24v Batteries...
Yes, it would be nice to have the equipment rated for 28-30V like the
Mikrotik's
But that is something we need to ask Ubiquiti to do
Pushing the existing equipment to 27v, has been documented to be
'in-consistent' .
:)
I just put up 2 new solar panels yesterday to replace 2 that were now to small
of wattage to cover the expanded load at the tower.
Panels with no load were putting out 35 vdc, at the batteries with load I was
seeing 28 vdc.
I use the tycon voltage regulator to maintain 24 vdc to the radios.
Because you are pulling more energy from a given cell. Current typically
flows in one direction at a time. If you are pulling current off of the
whole system all the time, AND pulling more from part of the system, then
there is never a chance for the system to come back to equilibrium. Think
of it
So it seems there are no 430 SMs left on the planet. We are in
desperate need of at least a 25 pack (we prefer 20Mbps SMs but beggars
can't be choosers).
Anyone have any in stock???

MPLS does run over a IP backbone, but can use VPLS tunnels to create what
you are doing at layer 2. Not to mention you would get all of
the benefit of Traffic Engineering, and internal routing giving you the
best of both worlds. Why its sometimes called Layer 2.5, as it creates
tunnels inside

That is a great way to explain it. This also causes a lot of other
issues with the cell/bank. As the one battery dies and takes less
voltage the rest start taking a higher voltage and over charge and out
gas leading to dry cells.

There are several things you can do to alleviate issues. Greg Osborn is
right. Most customers don't know a difference. We do several tricks on
various networks.
1.We do 1:MANY nats at every POP. This way only those customers at that
site are natted out a Public. This way the entire network

Volt meters are typically very high input impedance, 1 Mohm or more,
so that they don't have any effect on the circuit when testing.

Megaohms though, probably 30 MOhms or more. It's negligible.
