Price on another drops even lower? $129 12v 100ah

Main feature, only reason I bought my Wattcycle battery was cold cut off.
 
This screamin' deal is still available. I'm tempted to buy a few, even though I can't think of what I'd use them for.

I ordered 2 of these, but instead they shipped me two 24v 100ah (B24100H). Same look, still has Bluetooth and heat, trying to decide if I should keep them. I would need a 24v DC to 12v DC converter to run my 12v stuff but inverting to 110AC might be a little more efficient?

Her.: Because it was on sale … !

Me: ok , when you put it that way..

Me later…: Lord…I’m ready … take me with ya soon.🤣

I started to buy one of these to test them at the $129 price till I noticed its not prime and has a $30 shipping fee so its a $159 battery. Still tempting till I read this in the reviews :

------------
I purchased 4 of these batteries 2 years ago for my offgrid solar system, I had them wire 24volt 200ah .
I needed more capacity so I ordered 4 more in a one month period. When I went to charge each battery individually to balance all the batteries before hooking them up 24v 400ah .
I found that 3 of the new batteries would not charge past 13.5 and 13.3 volts. While my four 2year old batteries all held 13.8volts for 4 day. The new batteries are also 6 pounds lighter.
I'm not saying they are a bad battery, I'm just pointing out the differences. Looking forward to see how they work out.

------------

Sounds like they pulled a cell or something but that doesn't work out math wise so not sure with the lower voltage max and being lighter weight.

I'll pass.

Yo crow…Good call … 6 lbs lighter… hmmm.
Sounds like bait and switch hustle to me……..
Put somthing out realmgood …then change the internals to lessor quality to profit on the good press and ride the past reviews on the slow ride down with lesser quality ..

Big Bucks…

Form a new LLC ………and start over…

One of the oldest tricks around in the last 200 hundred years over here…

Yo China …we love ya …..yer so clever…

I hope I can afford SOK for my next bank. I don't care if they are more, I'm just tired of china junk deals and all the issues.
 
You get what you pay for, the real test is how these will be in 2-3 years. I'm tired of seeing these cheapies not charging about 13.1 volts because of cell imbalance and other issues. Atleast with the SOK you can open up and run a manual active balancer to correct them.

my cheapy balances perfectly. 0 issue.
 
Thats nice let us know how it fares in a few years after you have a few dozen cycles on them.
considering all the comments from all the 48v server rack batteries about out of balance. I really am not that concerned, i will pop the lid if it gets to that point and manual balance them.
