[RE-wrenches] Big AGM's and 24V Lithium batteries

[Andrew]

Hey Howie,

                I would recommend staying away from them as well, I had a faulty battery out of the box and it was a nightmare to get them to warranty it, took about 2 months of back and forth for them to agree to warranty the battery. Discover has an excellent YouTube video on the breakdown of the internals theirs vs. the competitor and it’s pretty eye opening.

Jerry,

I'm looking at all the lithium options out there for an application phycisist client who wants a lithium backup system. Can you elaborate on why Simplify is slow low on your list?

Thanks,

Howie

I agree with Kevin, the Unigyll are a great option, simplify would not not even be on my top 10.

Hi, 

 

The East Penn UnigyII 2V AGM batteries would be my recommendation. Can go up to 2,100 Ah with single string of 12 x 2V cells. More if you parallel of course.

G'Day All,

 

Came across an older DIY 24v off-grid system. Looking to replace current AGM  SunXtender batteries with less then 4 years on them but severely abused. Client won't go for my normal Rolls/Surrette because they are very sensitive to smells. 

 

Thus I was considering LiFePo4 batteries however I'm having difficulties locating them in a 24v bank. If you know of anyone that goes that way please let me know.

 

So if I'm stuck with AGM's stored indoors what brand would you suggest for a heavy usage (1,500 Ahrs +) home?

 

Thanks,

Christopher-
