[RE-wrenches] Aqueous Hybrid Ion batteries

[Dave]

Wrenches,

 

Thanks for all the info on this topic today. 

 

Big question for me is. What are 3,000 (manufacturer claimed) deep cycles at
100% DOD worth vs 2,000 real world 80% DOD cycles on a HUP battery when the
AHI battery's voltage drops below inverter operating voltage range at 50%
(more or less) DOD?

 

How would the AHI battery ever be discharged to 0% when the inverter cannot
operate at such a low voltage? 

 

My customer wants 33,600 Wh of usable storage power. So, what do we need in
Amp Hours of Aqueous Hybrid Ion's to give us a usable 1,400 AH @ 24V?

I would think we need 67,200 Watt hours of rated power vs. about 42,0000 Wh
of HUP batteries.

 

I'll be very interested to see the pricing on this battery bank, which I am
expecting tomorrow.

This battery module-I have one sitting in my warehouse-is rated at 3,000
cycles @ 100 percent DOD.  I don't know of anything else that's comparable
on the market these days with those kinds of specs.  

 

If it performs as advertises, it's hot stuff.and not cheap.

Yes, that voltage range is a problem but it has evidently been improving.
It used to be much worse.  We will see.

We have been asked to lower the DC input voltage to take advantage of these
batteries. What engineering is saying is we can't go low enough on the low
side and still produce peak AC voltage. Seems these batteries are catching
on might need to revisit this again.

Aquion's technology is evidently getting better and better from what we have
seen.

Ryan Stankevitz from MidNite may be able tell you more if you would like an
external opinion

Wrenches,

 

I have a customer with a grid-tied w battery back-up (formerly off-grid)
with failing LA batteries. He found these batteries on the web and asked me
to check them out.

 

Anyone out there know anything about this AHI technology and or this
company, Aquion Energy?
