EVE 280A cells black Friday sale.

[Scoob]

It doesn't seen to save much over just buying a complete battery even at the sales price or am I being goofy?

I could not find many of the whole batteries that had a decent bms with bluetooth.
The ampere 200ah with bluetooth is like $850

My house was the test.

? This is not helping... so basically you have no idea what they were then.

How much does it cost to build a complete 16 cell setup with these and how many watt hours do you end up with?

16 cells X 280AH X 3.2 Volts, wouldnt that be 14.3Kw?

16 cells X 280AH X 3.2 Volts, wouldnt that be 14.3Kw?

Let's go 8 cells then.

 

[Scoob]

Let's go 8 cells then.

Is math that hard?

8 cells X 280ah x 3.2 volts = 7.16kw

Let's go 8 cells then.

Why not 4 then?
How about telling us what your requirement is first?
Are you trolling?

How much would it cost to build a 7.16kw pack, BMS etc.

I know you're probably starting to feel lonely around xmas time but it's ok to not answer if you're unable.

No, I'm curious as to what it compares cost-wise to readily available server rack batteries on the market once you wire it up with bms etc.

I like the idea of diy bit if it only saves a few hundred bucks and I have to fab up my own box then maybe not worth the time.

 

[Bud Martin]

You know the price of thee cells being sold in the website in this thread, so you know the price of the cell, then you need just add the price of the BMS that will suit your requirement.
So what is the price of the rack mount battery with 7.16kWh? Do you have the price?

Like I said to the other guy, you don't need to reply to my question. It's OK to pass it over if you're feeling ornery.

45 day 280ah cells $145 x 8 cells = $1160
overkills bms with BT =$145
Total $1305 for 7.16kw = .18 wh



Box who knows, i wouldn't want a server rack battery so I have no idea there.

It's more about you demanding everybody do your math for you or you wont be happy. You see the prices but somebody needs to figure the exact cost to see if its worth YOUR time.
Maybe figure your cost for your time. What's your going rate for math charges?

Thank you!

I thought more components and materials were involved than just batteries and BMS.

 

[Scoob]

Thank you!

For comparison a eg4 with only 200 amps would be $1424.00 or .28 per watt hour.
But again I have no idea what a box cost. I have been looking for rv use so I only look at the 4 cell boxes and they are $35.00 for 18650

Ok

Looks like diy with just batteries and bms saves about 30-50% but then you still need to factor some sort of packaging/box to hold them.

On the contrary. I know exactly how many ah's I got out of my cells. You can't get any better than real world testing, in my opinion. I don't care how much power it will give on a bench. That's not how I will be using it. I bought them to power my house.

It would depend on where you are using them. If in a mobile application, then they need to be fixed in place. Mine are in a permanent location in my house. So, they are just sitting on a shelving for efficient use of space.

A BMS is only $102.00 for a 14.3 Kwh setup??

Anywhere from $60 to over $300. Depending on how fancy and what features you want.
