Does anyone know of any ~7.68kwh prebuilt batteries outside of cloudenergy
Even better would be bare cases designed for 150-160ah cells
If the latter, I’ll need to dig dimensions as it doesn’t seem cells are as universally sized as the larger ones.
The cloud energy batteries offer an interesting opportunity in weight. Only 25lbs more than 100ah rack batteries and 50+. Lbs lighter than larger ones. 2 would have the same kWh as 3 5kw variants

How does that work then? Have they found some prismatics that have a better power to weight ratio than regular prismatics. I can only imagine they are not LFP then, otherwise EV manufacturers would be using them? :unsure:

When I’ve perused the likes of 18650 and others website I’ve selected nearly every cell they list for sale. They don’t all weigh the same proportionally
I don’t know why. They are typically all listed as catl, calb, eve, lishen, rept, or similar cells.
They are indeed LFP
For example: EVE LF100-16 cells listed as 67.58lbs. EVE LF-105-16 cells listed as 69.69lbs. EVE LF-160-16 cells listed as 105.6lbs. Higee 120ah-16 cells listed as 100.62lbs. EVE LF-230-16 cells listed as 144.67lbs. EVE LF280K-16 cells listed as 190.78lbs. EVE 304-16 cells listed as 193.24lbs.

That’s raw cell weight of 16 cells together. As the cells get larger, the cases and the metal used for those cases get larger.
So the weight discrepancy of raw cells from 105ah to 160ah is 35lbs. The discrepancy from 160ah to 304ah is 88lbs.
The 230ah cell weighs less than 2-105ah cells.

I imagine it has to do with form factor and case material amount as much as anything else

I ask because I was looking at the ecoworthy 50ah 48v rack batteries. They are light so easy to move alone. My 15kwh cases require a team lift.
I can lift an eg4/Sok battery solo, theoretically I can lift a cloudenergy battery solo. I cant however, lift a 230ah or larger case solo. In the end 50a is not enough, 100a BMS is fine but if I’m gonna lift ~100lbs then what’s 30 more for an extra couple kWh

Do those 50ah 48s actually fit in a rack mount? Obviously no ears to secure them but thinking just in terms of sliding them in.
 
We guarantee that we use lifepo4 battery cells, and we have a 5-year warranties. The reason our batteries are lighter is because we have specially customized the corresponding casing for the 150Ah battery cell.

LFP comes in Prismatic Blocks, Cylindrical & Pouch format. The lightest cells are Pouch of course but it is not a huge difference. The cylindrical end up weighing more in the end. "Case" weights vary of course depending on design & material used.

Do Note just in case, that many prebuilt racks have weight limits... Gravity ALWAYS WINS !

This year we will also launch 50Ah, 100Ah and other stackable batteries. Stay tuned;)

What company do you work for?
You need to show your affiliation in your title.
Do you sell raw cells?

Do you work for cloud energy?

Check the size of the 150ah rack battery. If it is 50% taller, have you gained anything?

I think with the 48V 50Ah you really need to consider at least a pair as your first purchase. Then you have a 100A of BMS and further additional expansion can be done one at a time as budget allows.

To me it's not worth putting body at risk trying to shift heavy loads, unless it's something where you have racks/shelves and a rack scissor lift to do the hard work for you.

I figured if they weigh around the same as my generators and welding equipment that I shouldn’t have much to balk about
I was keen on the 50ah packs for a bit but then I’d want 4.
It’s a weird need/want/use case that I’m being stubborn on is all
I was able to find out that gokwh offers 7.6kwh/150ah packs so I may snag 2. In reality the normal Sok packs would be perfectly fine, but then I saw I could squeeze almost the equivalent of a 3rd battery with these

For $360 a 50Ah pack even four is really not a mega hit on the budget.

At that point, get the 300a EG4 Powerpro.

Nah. I’ll continue to build 2 of equivalent capacity for the price like I already have.
Again, this is a specific use case hence my stubbornness
I do appreciate the spitballing of bouncing ideas back and forth though. It forces me to continue pondering. 🍻

Edit: to clarify. I have 2-15kwh batteries for my portable build right now. Unfortunately that creates substantial tongue weight. 2 of my rigs don’t care, one does. If I decrease the battery sizes I can shave some weight and maintain the overhead I desire. Hence my pickiness on cell size in this instance

No it’s picking things up and putting them down twice as many times not the cost.
Which invokes some type of subconscious rage in relation to San Antonio Texas standing on yellow dots being yelled at by some dude in a mountee hat yelling at me to pick my stuff up and put it back down for seemingly hours on end
🤣🤣
Like I said, I’m being a weenie
