I would like to know if anyone on this forum uses these batteries or similar batteries by US Battery?
The Manufacturer Specs call for a FLOAT of 7.51 volts or 13.02 volts for 12 volt systems..
I normally always want to follow guidelines by manufacturers as they built their product and probably
know how to care for it...
I just think this is kind of low and I have been setting 13.4V for my Float on the classic! I'm hoping
that this won't lead to problems for me in the future! I don't want to end up cooking the plates much before they should be...I don't find any unusual water usage and everything seems quite normal..
SOC first thing in the morning is still 100%...
As a matter fact, I've had these batteries now for over 4 years and my previous MorningStar Tristar
60 MPPT was set for 13.4V with no ill effects for that whole time!
Should I stay with my present 13.4v or use the recommended 13.02v given by US Battery?
Hi St,
Think that there is a Typo in that 7.51 V per 6 V battery for Vflt. Bet that you are really saying 6.51 V X2= 13.02 V.
Generally, for Flooded batteries, one wants to choose Vflt that just BARELY keeps a fully-charged battery, fully-charged.
So choosing the lowest voltage possible is probably best, especially if the battery spends a lot of time in Float.
Just be certain to use a BTS on every charge source, and use the appropriate Temperature Compensation value recommended by the manufacturer.
FWIW, Vic
Vic...Thanks for the advice! Yes that was a typo error! 7.51v float would definitely cook the batteries!
There are times that the batteries stay in float for a long time...so I guess I'm going to change the FL
value down to their recommended setting of 6.51v or 13.02v for my 12v system and see how things go!
I'm really only expecting to use these batteries for another year and then going to change my Batt bank
this coming Nov or Dec to probably AGM 2V units!
I can always go back to my previous setting of 13.4v or somewhere in between say 13.2v for float if I
feel they don't stay up like they have been...
Thanks for the good advice! BTW I really like this forum and I find it is time well spent..All the major
contributors seem very eager to help!

Pretty interesting rig there.
What kind of velocepede is short enough that it fits across the frame inside the legal width limits?
My wife's Fiesta has an 8 foot wheelbase and is about 13 feet bumper to bumper and it is a small car!
Sorry to divert your thread.
Tom
Tom...Our 2011 Mercedes Smart Car has a wheelbase of 72 in and bumper to bumper of exactly 102"
which is exactly Legal Limit with no permits...Our previous 2005 Smart was only 96" bumper to bumper.
This arrangement works very well..
St,
YES, great looking TowRig and Trailer.
I, too, had wondered about that car, AND, how it gets deployed and stowed.
Do you use ramps, or is it some complex hydraulic movement of the car platform, ... or ??
Thanks, Vic
Thanks for the comments! I use a set of Custom made Aluminum Folding 12 ft ramps that were
made in Springfield Mo for me with a Custom bend near the top to combat high centering.
The ramps fold to 6ft long and capable of 6,000 lbs total weight...They also store under the deck
very neatly for transport and storage! I use a winch setup with remote control to bring the car up
and I just drive the car off...very simple and easy to do...Car goes up onto the truck in about 15
minutes from setting up the ramps to securing down the car on the deck...very slick...
Here are some more Pics of my Setup....Thanks for all the Interest...
Dog people, too! :)

WOW! Too cool, looks like you are having fun!
Vic
Yes...Vic I am having Fun!
Thanks for the thumbs up👍
ST, just read about your ramps, can you drive up & on and go off & down the other side?
My quad trailer has that option if carrying 2 quads... sure beats driving off backwards... :)
whats the voltage of the Volvo ? Tractor !
24V in series parallel system ? some have the dual charge ALT's & that could charge the 24Vdc battery bank while in tow.
since your asking about upping your system to 24Vdc

Wb..The Car Deck was designed with Wheel Stops on the curb side because the car only
has the facility for Eyebolts that are frame mounted on the rear...The car needs to be pulled backwards
up the ramps and then the car can be driven forwards off the truck deck down the ramps!
It's actually a very easy operation to do and can be done in very little time! I've done it probably a couple
of hundred times at this point and can be done with my eyes closed!..(not quite)
The car is only 2,000 lbs and the ramps are super solid...5 Star Manufacturing in Mo custom make ramps
for any purpose, all the way up to D9 Cats...1st class quality ramps that will last a lifetime!
I had a Welding Shop here in Arizona fabricate a Truck mounted 2" receiver for my removable 6,000 lb
Warn winch and with the remote control, going up the ramps is effortless and a breeze, plus I can control
the exact placement as I hit the deck...It's all done in virtually 10 min. from ground to tie down on truck! I am a member of a HDT Forum on Escapees.com...http://www.rvnetwork.com/index.php?s=3e999dca1e4283ed79b90badbe5e6335&showforum=32...We are a few dozen members that all have Big Badass Trucks and Trailers, and have Piggyback Smart Cars! :D
CDN-VT...The Volvo ALT Has only 12V output. I was looking at increasing the Battery Bank Voltage
to alleviate some of the Heating Issues I'm having with the Classic 150...The Voltage of my panels
is quite high, 2 panels in series just puts me very close to the max...I'm in the process right now
rewiring to 4 strings instead of 2 and see what difference that will make...The added benefit of using
all parallel strings is that any shading on a single panel only affects the output of that panel...and not
the other one in a series string!
The roof of an RV has limited real estate, and one doesn't have a lot of options as to where to install
the panels..You just have to use all the available space and deal with any shading issues!
I am still going to investigate the 2 battery bank option though! WB..makes a good point about allowing
one 12v(small bank-232AH) for RV house lights and small 12v native only draws...and one 24v bank-464-AH bank for AC_Inverter loads only...What's your view on this scenario?... 8)
There is another thread on that panel voltage & replys , so lets just keep it there.
I have seen alts in duel , so thats all i was asking . I did reply on the panel thread Sir.
VT
no problem!
