$220/kWh. Not bad for pre-built.

 

[JoeHam]

Yep. They dropped the price the day mine arrived.

I paid $75 more than that . I cajoled them into a $15 refund after much back and forth so I have that going for me ?.

The steel case and nice spring loaded handles made it worth it to me for a portable project where I need 50 Amps max output and life is too busy at the moment to do another DIY build.

Is picking up 3-4 of these worth it compared to server rack batteries? The server rack battery storage is an obvious plus but other than that is it worth the additional cost? What's the major difference between 50ah and 100ah.

No, one decent server rack battery is a better option than paralleling smaller ones. This is barely cheaper than a Lifepower4 with shipping right now.

At just under $1130, including shipping, for two of these it is a significant cost savings. For an old fart like me it is also significantly easier to move two of these 50 pounders rather than one 100 pound server rack battery.

I would definitely say it is worth considering @TheHappyNomads

I will have one GYLL (the older EG4) 100 Ah server rack, one 100Ah CALB DIY battery I built and two of these all paralleled together for 300 Ah (over 15 kWh) total.

After the price drop I couldn’t resist getting the second one.

From where? I'm seeing Lifepower4 batteries for $1000+/ea??? This is part of the reason for my initial question as I wasn't seeing anything that cheap for server rack batteries

Yeah It was a brain fart, I was thinking 3 of these vs. 1 server rack for some reason.

I'll never buy a pre-built battery again.
Diy for the win, every time.

It's not mine. I just work on it sometimes.

Would you care to unpack why?

Cost.
I like to get the most out of my money.

The fake QR codes stuff makes DIY packs a less friendly experience for newcomers imo. The less risky purchasing options remove a lot of the cost benefit over server rack.

 

[timselectric]

Only buy from reputable companies.
I buy my cells and BMS's from 18650batterystore.
They arrive in 3 days. And are part of my system that day or the next.

I have used/handled over 100 DIY cells myself, and have never once looked at or tried to use the QR code.

Your suppliers reputation/work ethic is far more important than a QR code.

 

[timselectric]

What's this QR code that everyone is talking about? lol

What's this QR code that everyone is talking about? lol

The only thing I ever used the QR code for is to take a quick inventory using a QR reader on my phone. It saved putting in those long numbers into my spreadsheet.

 

[timselectric]

I have never scanned them.
I might, if I ever had a problem.

Even if you had a problem, Is it going to tell you how to fix it? My understanding is it gives you meaningless information that can be forged pretty easy
