I think it was measured at 75 AH. Stone blocks added so the shipping weight would seem correct.

Re the price. those change on a daily basis. Just now with the news all about the backlog at LA/Long Beach harbors and most LI comes from China as I recall. the price is ^^^ once the supply chain starts moving again VVV

Looks interesting. ... Quesiton about battery management System. does it even have one?
Home was where I park it. but alas the.

Careful you don't end up with one of these batteries for low price and claimed high capacity:

You mean assembled in Nevada.

The only reason I mentioned this battery is because it got a very high rating from Will Prowse. $399 100Ah 12V "Zooms" LiFePO4 Battery Review

If you have not seen any of his YouTube video you need to know that he has been evaluating and testing solar equipment for over 4 years. I trust his opinion.

Concur !

This is why a fuse should be as close as possible to the positive terminal on the battery and the positive post needs additional protection.

To put it in perspective:

A 100Ah 12V battery has around 1.2KWh of energy stored in it, 1 Watt-Hour has 3600 Joules of energy, so 1.2KWh has 1.2 * 1000 * 3600 = 4.3 million Joules of energy.

A hand grenade contains around 50g of TNT, at 4,000 Joules/g, that's around 200,000 joules.

So a 100Ah battery has the same energy as around 20 hand grenades. Granted, the battery is not going to release all of that energy at once, but still, a failure can do a lot of damage.

the first test he did shorting the termanals, which did nothing aside from melt the termanals, would have caused a lead acid battery to expload. right there it is safer than a normal battery, as that would be the most comon issue from people working around there batteries. and it isnt like the old nickel metal hydride batteries that are subject to thermal runnaway, but I guess if you go around shoving metal spikes through the battery..... maybe thats why they are in a protective case?

Fakespot is a fraudulent company

They are pretending to be unbiased and legitimate when in fact their "algorithm" is broken and the results are completely incorrect. It's a good thing no one uses fakespot or even knows about this terrible company.

Read Customer Service Reviews of fakespot.com - Trustpilot

According to Trustpilot.com Fakespot is a fraud then maybe Trustpilot is also a fraud????????
