Alright guys since we have one heck of a thread going on the new Midnite The One AIO I thought I would go ahead and start a separate thread for discussion and review of the upcoming Midnite Battery Systems both server rack and larger modular sizes.

First question when can we expect to see pricing and availability?
 
7-1 edit - this was written to be sarcastic, hence my comments at the end.

I heard they are user serviceable and cost $100 / KWh shipped assembled or $75 / KWh if you put them together. They have 5A active balancing, a class T fuse is included and they use standard terminals for connection, the BMS also has Bluetooth and can communicate with solar assistant, oh they have all the fancy certifications too.

I hope it wasn't a rumor or a dream...

Has ANYTHING official been released yet? or is this a best guesses thread?
Best guesses to my understanding. I believe we’ve heard from Robin or someone similar that they will be more cost effective than the competition and have all the certs
 
Here's one recent post:

Any info yet on when these will come in stock?
Anticipating Late June on the 5kW and likely late July on the 16kW the wall mount with the heat and fire suppression is a little slower going through listings. The app is currently being worked on to add the battery into the same Midnite app and all is going well on that front
 
Integrated stacking without needing rack mount enclosures, nice.

Seamless firmware updates via the aio app is a big improvement over the chaos of the eg4 batteries, and auto battery id assignment no more dip switches.
Is there a benefit to the rack having a busbar vs cabling them one to the next?

Im looking for to seeing @Will Prowse open one up! Also looking forward to hearing the price point.

Wait. $100kwh? Either I didn’t have enough coffee yet or that’s $500 for a standard rack mount battery?
 
Hopefully Midnite get's these out at a "proper" price point.
I have some reservations about it as they are NOT Battery Builders and TBH some of the stuff Midnite Folks have said about LFP, voltage Ranges etc is concerning too. DON'T GET ME WRONG, I LOVE MY MIDNITE GEAR & It's a Great Company ! But like everyone else they are not perfect but very good at their OWN Bailiwick.

I will wager NOW: They will likely have Charge Params that push it to the edges rather than a trouble-free Moderate Profile recommendations.
Last note is regarding the cells: I doubt these are USA made/sourced, so for the time being the Duties are a non-issue but next year they will be. Of course that will affect costs later.

Once we "SEE" the full tech specs and are able to "look" at the BMS used, cells + assembly and "beat on them" a bit in real world conditions, I suggest Calmly Waiting before leaping into something.
 
I think only other builder that lists EVE cells in the specs is Dan at Trophy, the rest won't disclose:

I'll take that wager. I doubt they are going to get to 8000 cycles by pushing the edges.

My Pytes Ebox 41000R batts use REPT cells. they are rated 6,000 cycles. Granted, these may be a different version battery. But what is important to know is that EVE and REPT cells are a first class quality cell, just like BYD cells.

I think everything is important in life expectancy, the casing, circuit boards, ventilation, BMS quality and software, etc.

Im ignorant but maybe someone can help. Where to the cycle ratings come from? Is there a specific test procedure?

They come from the manufacturer based on their knowledge of the chemistry of the cell, but ultimately the warranties are all from the battery integrator who places the cell into a housing, attaches temperature monitors, a BMS, any heating or cooling and ventilation and then decides how much a battery can be discharged and how many cycles and time to be warranted for.

Some warranty coverage is to a DOD (depth of discharge) of 90 percent, others to 80 percent, still others to 70 percent. Then some warrantees also add in a total system number for the batteries in kW charged and discharged, regardless of the DOD. Then there is the number of cycles. Lastly, the warranty may require a careful record of the actual charging and discharging cycles to make a claim for premature failure.

IMO buy a quality battery, get a good price, don't over pay, and if you get 5-7 years or more you have made a good purchase.

Sakuu has shown on youtube a metal free battery (no lithium, copper, aluminum, cobalt, etc) that is a dry pouch battery lighter in weight than an LFE with significantly more energy density than an LFE. It is in testing and scale manufacturing research. But the point is in another 5-10 years I think the current lfe's as we know them will no longer exist or be very, very inexpensive.
