Tesla battery pack?

............................
So please stop being overly defensive when it comes to Lithium technology and the dangers associated with it.

My attempt was to show a cause and effect relationship between careless action and the fire. In my mind that was knowledge that could benefit the uninformed. One of the benefits of forums like this is to share knowledge for the greater good.
I have spent a good part of my career doing risk management and a close friend specializes in risk management with regard to chemical reactions. One of the first things that is done in risk management is to assess the risk and understand the causes and effects.
Charging every battery chemistry causes heat. Heat causes most chemical reactions to proceed faster. I guess it depends on ones point of view whether my comment was intended to increase knowledge or defend the Lithium battery industry. I will note your comments and try to choose my words more carefully.

I saw a post on diyelectriccar forum that indicated that the cause of the fire was major over charging of the Tesla modules. They did not spontaneously catch on fire. They were being charged by a FLA forklift charger.

Look. We understand that you and a few other members know the technology for lithium batteries. The problem is the vast majority of people that come hear are nu-bees when it comes to this technology and if they make a bad decision (like over charging) the end result is a fire or worse.

The Forum can't have a few people make posts that Lithium is not dangerous when we have to protect the majority that could get hurt if they play with the stuff.

When it comes to electricity or any battery technology if you become complacent or careless the end result can be bad.

So please stop being overly defensive when it comes to Lithium technology and the dangers associated with it.

We have been trying to try- can I say that?- the LG Chem but they are not available. My last order placed 6 months ago is still not fulfilled and we buy LG solar modules by the container. I am looking at the Tesla and Sonnen right now - at least i can a get a couple of those

Small scale /residential electrical energy storage seems not ready for prime time at this time.

Anyone seen the latest amateur attempt at re-using Telsa battery packs? They electrified an old Disney vehicle and had bit of an issue while it was inside their shop.........

Interesting. I wonder if the two things could be related (software and deployment issues, availability).

LG's industrial pouch/sheet manufacturing process seemed like it would have a chance at making some of the "best" LFP cells. I wonder if their core cell manufacturing is doing okay.

Hey solar pete, are these Resu home units you've tried? Can you tell us more about the kinds of issues you've run into?

Yeah we have been using these, https://www.solarcart.com.au/lg-chem/

Some issues have been
they dont work off grid as in we cant get them to work nicely with generators, we have tried a few and they just dont like them
software glitches, we are on I think the 3rd software upgrade
they dont make financial sense
Winter,the turd sandwich scenario

Cheers

I appreciate the input
the TMC site does have some good client experience info.
Thanks

We have been using LG Chem batteries with mixed results, there have been all types of issues so we have been preferring to stick to doing the solar because of the economics

Hi All,

I dont have any first hand experience with the Tesla Powerwall's as we chose not to be a Tesla installer (yet) as they dont allow enough leeway to do whats required to do it properly on the install side costs wise. They want to set an install price but it just dont work in the real world.

We have been using LG Chem batteries with mixed results, there have been all types of issues so we have been preferring to stick to doing the solar because of the economics, in OZ power is expensive so solar panels mostly pay for themselves here in 3 yrs where the payback time of a battery is still a bit of an unknown as I dont know of any one who has had a tesla or LG battery running off their piddly little 5kW system for 10 years yet. One of the major issues that pretty much all clients I speak to are oblivious too is a thing called winter. In winter you have to make a choice between two turd sandwiches. One, let your battery be flat pretty much most of the time or two.....and boy twos a doosy, you can pay full price to take power from the grid to charge your battery all the time, during winter.

So the jury is still out about these new fangled batterys. In other news some old heads may remember we did a 30kW hybrid system at the boss's place a few years back and used cheap chinese batterys to see how they would go, well they went **** house. We pretty much re jigged his whole set up with these BYD batterys and Victon gear, so time will tell, cheers

Thanx for the update and opinion by someone who probably knows more about battery/storage and residential interface than a lot of DIY yahoos.

Seems like small/residential scale electrical energy storage is getting closer to prime time but not there yet.

..........
Does anyone on the forum have any experience with the TESLA Powerwall V2?
.......

I posted a response on the other thread where you posted the same question.

Here is a link to one thread on TMC:

https://teslamotorsclub.com/tmc/threads/tesla-we-need-more-control-over-our-powerwalls.134213/page-3#post-3202431

There are a number of threads about the Powerwall on the Tesla Energy section of that Forum.

[Scott Sousa]

This has been a fun post to follow, but seriously.
Does anyone on the forum have any experience with the TESLA Powerwall V2?
I am interested in the install experience as well as the performance.

Folks wanting those "cheap" used batteries from some unknown donor vehicle keep telling themselves it won't happen to them. Nice light show though.

At the first signs of fire, the guys tries to blow out the flames like it's a birthday candle! At around 6:18 in the video you see him hit with flaming debris as he keeps getting close with a fire extinguisher trying to put it out or manage the exploding cells(10) My first Tesla Battery Fire - YouTube - Google Chrome 11272018 64329 AM.jpg.
