Just the "Bright Way" name itself has that aura about it.  :-(

In fact, check this page:

https://www.amazon.com/Brightway-Sealed-Replacement-Rechargeable-
Battery/dp/B07L6RK333

or  https://v.gd/WaRhAR

The battery in the photo does indeed say "Made in China" on it.

I couldn't find much else about them.  But here's a forum thread discussing 
Bright Way (or Brightway, I've seen it both ways) batteries:

http://sci.rutgers.edu/forum/showthread.php?261445-NuMotion-and-Brightway-
batteries

or https://v.gd/yAhw3w

It gives a website for the batteries -- http://www.bwgllc.com

I don't see anything there about a warranty.

If you can live with lower capacity, youi might consider East Penn Deka 
Intimidators in type 8A31DTM.  These are group 31 AGM batteries made in the 
USA.

   You may want to check to see if Bright Way is just some outfit that buys 
   nameless batteries in China and slaps their own labels on them.

How would I find out for sure?

   The evdl archive shows you have asked about batteries for your 48V (6
   group 24 8V batteries).

That was the original configuration, but I went to 4 12V AGM instead.
I've lived plenty of my life with flooded batteries and I would not want
to go back to them.  I especially didn't like the acid mist.

In truth I don't care that much about cycle life -- mostly about
calendar life.  I have had my UB AGMs for 10 years.  They are down
to maybe 25% of their original capacity, but still usable if you don't
mind charging often.

I have no experience or knowledge about Bright Way batteries. But 
suspicious old me says that 1000 cycles from an AGM is an extreme claim. 
Extraordinary claims demand extraordinary evidence. Where's their proof?


You may want to check to see if Bright Way is just some outfit that buys 
nameless batteries in China and slaps their own labels on them. In that 
case, they could be anything. They know darned well that you can't 
verify their claims until after they have disappeared with your money.

I don't know the batteries you posted, so I can't directly answer your
question.

The evdl archive shows[
http://electric-vehicle-discussion-list.413529.n4.nabble.com/template/NamlServlet.jtp?macro=search_page=413529=ken+olum
] you have asked about batteries for your 48V (6 group 24 8V batteries)
tractor [ox
http://cosmos.phy.tufts.edu/~kdo/electricox/review.html
]

Agm do not cycle (or last) as long as wet cell. An 8V wet cell would give
you the cycle life you seek (or change over to li-ion).

Though Interstate is not the best battery [

], there is a distributor near you [
