Those have unknown origins, and almost certainly have been subject to high G forces. I don't want to burn the house down.

Pretty much everything. Nicad could survive that rate. Maybe someone here will buy one and take it apart to see what's inside. I'll bet cheap pouch batteries from China.

Sure but it's source power can't do more than 2kw. Solar or 12V car is going to be really slow and the AC is 110V. The battery isn't the limiting factor, it's the power you are giving it to charge.

I"m not saying I believe it's solid state, it's just you won't be able to tell without taking it apart.

Well I don't believe these are solid state. Not when they are fast charging at 2kwh rate. So pardon me but I'm going to scream when something sounds like a scam. Really don't want someone to get taken.

Wow lol dude.. A scam.. why because you don’t believe that solid state batteries could exist? Let me give you a little tip, pretty much anything you can buy with a credit card is not going to be a scam. Such a good scam they tricked an unbiased battery reviewer with 48k followers.

If it wasn’t what they said there is 0 chance that a 2.6kWh battery would weigh 50 lbs. Also highly unlikely it could output 4kW.

It seems pretty clear you don’t know anything about battery technology or the like so not sure why you keep digging yourself into a deeper hole here.

Solid state doesn't automatically mean they can be charged faster. There's still a lot of dependence on material choices to get the capability. Even solid state batteries are going to have the tradeoff of capacity vs charge rate, and if you're engineering your device to only ever need to be charged at a specific maximum rate, you can select cells knowing that, and potentially end up with slightly less weight or a higher energy density as a trade-off.

I've done a Prius lithium swap from the low power nimh. About the same rating as this "SST" and the cells weigh 35lbs. You have a different experience?

Also a 2C rate is not unusual for a lithium pack. Afterall, the Rivian charges at about 2C. Ive run packs at much higher rates but their life is shortened and they swell.

It’s definitely not a 0% chance. My trailer batteries have a capacity of 2.6kwh and a total weight of 52lbs. The same company (Renogy) also makes a single 2.6kwh battery that weighs 47lbs and has a maximum discharge rate of 5.1kw. It’s entirely possible to build this battery with conventional LIFePO4 cells. Obviously some weight will be added with an inverter/charger and casing changes.

That is just the battery cell. You have to compare like product to like product.

For example:

1.5kWh Goal Zero Yeti power station - 45.6 lbs
3.0kWh Goal Zero Yeti power station - 69.8 lbs
Eco Flow Delta 2 Max - 2kWh - 50 lbs
Eco Flow Delta 2 - 1kWh - 27 lbs
Bluetti AC 200 Max - 2kWh - 61.9 lbs
Jackery 3000 - 2.8kWh - 63.9 lbs

compared to:

Yoshino B4000 - 2.6kWh - 53.6 lbs
Yoshino B2000 - 1.3 kWh - 31.3 lbs

We don't know what the battery cell itself weighs but clearly the full package (case, inverter, MPPT, charge controller etc) is at least 30% lighter than any competing products.

So yeah to some people a 30% weight reduction (and a higher power output) would be worth a 20% premium but I don't expect you to understand that. Put another way that would be equivalent of adding 85 miles (38kWh) of range to my R1T for the same weight!
