I am looking at a fire ball extinguisher to place above my PW in case something happen. Wonder if someone else have it too and which one did you get?

I wouldn't recommend putting a fire extinguisher near the thing you think will be on fire. I would put it some where away from the PW that is easily accessible.
That said, if you insist on having a fire extinguisher for your PW, use a standard ABC or dry chemical fire extinguisher. Litihium ion batteries are considered a Class B fire. Link to article below.

How Do You Put Out a Lithium-Ion Battery Fire?

That's a little over my budget. I will see if I can setup a GoFundMe for thisIMO, I think the safest bet is the following. Vines and Wwhitney can help to design this...
1) Mount the Powerwalls on a concrete slab. Preferably one with a solid rebar base of at least 8 gauge.
2) Then make sure you put some bollards around it. Needs impact rating of 3,000 Newtons (to stop a Cybertruck).
3) Make sure you put some rise of rate heat sensors above the Powerwalls and below the Powerwalls.
4) Make sure your conduits are "quick disconnecting" (Eaton or Square D is fine)
5) Then what you want to do is rig up some high power explosives under the concrete slab (explosives must added after the concrete has cured).
6) If a fire is detected on this concrete slab, then the explosives will detonate.
7) The result is the Powerwall will be blown away from your house... at least 50 feet.
8) Then it won't be your problem any more of a thermal runaway event in your garage.
(it seemed cooler in my head when I first started thinking about this).

The reason the fire ball is pretty much useless, is that if a lithium battery has gone into thermal runaway nothing is really stopping it, short of crazy amounts of water directly on the modules within the steel powerwall enclosure.I am not referring to a regular fire extinguisher, but the type that you place above a electric panel and activate when there is a fire. I checked and saw lithium fire is class B and those extinguisher is for class ABC. That's why I was thinking to get 1 and place it above the PW.
I already have a heat detector installed. Just looking for another layer of protection in case something happen
