Batteries finally arrived....where do i start?

[Roqm]

I intend to parallel all the modules when i begin to install everything i am leaving them connected to they stay balanced, voltage sitting at 567v i only checked one today will open both when my gloves arrive...p.s kokam moduels (13s 3.7v nominal nmc).

What do you need gloves for?

 

[MadMax03]

Good god, where to start indeed. You building a nuclear power plant with those?

So i can keep my hands if a mistake happens

 

[Will Prowse]

Holy cow. Be careful ??

 

[Roqm]

Holy cow. Be careful ??

Waiting on gloves before i dive in....thanks ?

Na little battery for the house?

 

[snoobler]

Ah. High voltage. I though that was a typo when you followed it with 13S "modules". Then I read the data plate.

Then I pooped my pants a little.

Yes. Glubs.

Hi will have you come across batteries using a 2hr rating before? (52a @ 2hrs)

 

[gnubie]

Crikey, I thought it was a 56V battery too. That's a mistake you don't want to make.

 

[snoobler]

Heh... the key is 52A @ 577V to yield 26,500W of discharge power. In comparison the battery in a Prius yields a whopping 30,000, but it's tapped out in about 2 minutes.

i don’t know what to say other than

this is skookum as frig

stay safe buddy

Just to be safe when disconecting modules since the voltage of both assemblies are above 500vdc

 

[Roqm]

Just a small home solar set up....lol

Yeah. My brain didn't accept 577 and insisted you meant 57.7. Gloves FTW!

I am curious as to what they were built for originally.
And what type of cells they are Lipo, LTO, or other.
And yeah, 600 AC is a serious thing to work with, 600DC is wild.

They are "community energy storage" search for "energy storage project" on the tube

Also forgot these are li-on pouches cells.

Oh no. I believed you back on Oct 19, 2020...
