This is what 60KWH looks like

I would put these outside in a small concrete bunker with ventilation and only the feed cables going into the main building...

The battery looks portable but will never move once commissioned it will sit outside approx 400 mm of my house brick wall which will be lined in sheet to the required specs

This is important in theory, but without knowing the current pull by each battery in parallel, the reality can be different.
It seem that Austenpowers build a 74V battery, so except if it goal is to pull 40 kW from this one continuously, those cable are way to big for nothing.
I would like to know what will be connect to this battery, but I guess there is chance those heavy cable will pass less than 30A only.
That is still 11 000W (74V x 30A x 5)

16s x5 each cell is a 3p 60ah cell in 16s config each tower has 8s . The cables I had and I know there over kill but there double insulated and all the same length +-5mm

How do you know these aren't defective modules that came off Chevy Bolt EVs (the ones that caused fires and a massive recall) ?

I'm mean it's one thing to use second hand Lithium Ion packs, but whenever I hear LG CHEM, it makes me worry...

I do have to say that it looks pretty compact for 60kWh. Probably due to the higher energy density of those Lithium-Ion, compared to LFP.

These cells are dated 2019 and 2020 I'm assuming there replacement battery's as there performance would have dropped and been replaced with new I would say they have seen a fair amount of cycling with a high volt and hi current and now there going to power my home 5kw battery inverter so there going to provide very little current at 110ah devided between 5 packs and that's peek use ... really hoping I'm not in fire territory as it's low voltage compared to 900v in car many battery's in series.
 
Fun project. I’d want them far enough from the house that they could burn up unattended and not involve the structure. 15” horizontal to brick, maybe. What’s the vertical clearance to combustibles?

EV battery warranties are usually relevant if SOH drops below 70%.

Most modern EVs (excluding Nissan Leaf) have active cooling/thermal management which helps alot with minimizing degradation.

I really doubt that Hyundai/Kia EVs from 2019-2020 would have 70% SOH.
Just for comparison , my EV from Jan. 2021, with 40k km on it has 93% SOH.

I don't want to be a party pooper, especially since you already bought the batteries. But I really think you should know what you have on your hands. Be aware that these are most likely modules that came off recalled battery packs. With all the dangers included.

As an EV owner and fan, I followed the LG CHEM saga closely. Fortunately, my EV uses CATL cells. The LG CHEM packs were found to have a manufacturing defect, which causes internal shorts and hence fire/combustion.
Anyways, the one thing I'm not sure of with the whole recall saga, is, if they were able to identify or discriminate bad modules from good modules. I think that if the defect was easily identifiable, they would have found it early in quality assurance checks. The fact is that they didn't. Maybe because it hard/impossible to identify the defect on a working battery pack, until it's too late.

Just looking out for your safety...

Hopefully degradation will slow since they are no longer exposed to large currents, thermal cycles and vibrations.

Thank you for this comment.... I know I have cells that could ignite while in use . I know there impossible to put out till the chemical reaction stops .... I'm not pitting these battery's inside ... there outside ... there in a cement sheet and steel box ... the cement sheet is dual layer with fibre glass insulation between the layers if one goes they all will . I truly believe that the only danger to a battery fire is the battery box and battery's only ... these battery packs were striped and tested and reassembled but there was reports with them . Every individual cell was exactly the same voltage and I purchase 2 19s packs and 3 20 s packs . Not every ev with these battery caught fire .... we have to keep this in mind . It's a gamble when 100% operational this project will have cost me 1300 bucks Australian ?
 
Good luck !

Looks like a fun project and if your covering the fire hazards I think its worth going for especially at that price.
 
You know you can actually buy real sprinkler heads quite easily and plumb them into a suppression system. As others said it may not stop the fire but it will certainly slow it down. And I also like the plastic sandbag idea. Good luck to the OP, not something I would be doing given current knowledge.

Ok, so each pair of 8S battery is coming from a different EV (you have a battery coming from 5 EV) because most modules in a Kia/Hyundai are 10S.
So, 59V battery with 66V-48V range. What will be connect to this battery?

No every cell has the same info on them .... I've pulled the original ev packs apart and reconfigured them into 8s bricks 10 of them . The packs are compressed and contain original hardware to join cells.... it's been a lot of work really there definitely kia hyunday lgchem batterys

Nice! Seem a nice 5kW unit able to output 12 kW for 30s and allow an input of 40-68Vdc.
The main danger with your battery is in case of overvoltage/overcharge, so be safe and add multiple protection level.
Something like the inverter and/or the MPPT is set to don't overcharge, the BMS look there is no overcharge and a second voltage recorder look a the BMS and stop everything in case of malfunction ;)
 
This is the final set up bouble cement lined with glass insulation box . 60mm cavity on all side insulated.... closed cell foam seal and stored away from house .... let the reassemble and commission begin 17003702622714458696766782101985.jpg

Can someone tell me if the inverter communication cable is just strait through or do I have to have a pinnout for each end?
