SST portable battery power is finally available

Somewhat pricey however if you take into account the $$$ and amount of work required to perform an upgrade to one's rig, its versatility seems to check a lot of boxes.

Specifically, the B4000 (with 30A output)

Their claim of a solid state electrolyte is a huge red flag, no one has true solid state cells on the market at this point, technology is still in the experimental stage with plenty of unknowns, like a cycle life, etc. Many scam artists claim SS cells in their batteries, but when you tear them down you find typical cheap chinese cells inside. Beware!!!

I was also under the impression that these were still a way off. They claim a "solid" electrolyte as compared to a liquid, so I imagine we'll actually see if it's true when someone tears it open and drives a nail thru one of the cells.

Another trick of the marketing group? Maybe another small point where they are "fudging" a bit to confuse folks who read too quickly?

If we are used to looking at batteries and thinking a 100 AH battery can last quite a quite and then see this rated at 2611 WATT hours, could make a novice think it was a great big power supply! WRONG!

Converting the watt hours to amp hours, we get this being rated just slightly higher than two 100 amp hour batteries!
That's not like being able to run the air conditioner overnight! More like a single 1500 watt heater for less than two hours!

There are several solid-state batteries under development for automotive use, none are sold commercially.

In the Wikipedia entry, Yoshino is mentioned as the first company to produce a SST "Portable Solar Generator". I suppose I'll take it with a grain of salt as I heard they are scam artists.

Thanks for posting, it made me do some research before replying, instead of shooting from the hip_so to speak. It peaked my interest because of my background. SST in my world stands for Stainless STeel.

I find even the Manufacturers of Batteries Fail to properly State the Configuration of Battery Cells, as the Ah is usually stating what the Cell Rating is, as with Modern Battery Inverter Technology a 48VDC System commonly can safely have a Full Charge voltage of 51.2VDC of higher, without an adverse affects.

Leaving out the Cave-man LAB, and looking at the Safest of the Lithium Batteries, being LiFePO4 ("Lithium IRON" Not "Lithium ION" the Dangerous type), nearly all use Cells with 3.2VDC.

If Cells are 100Ah and configures 3.2V 15/2 (Series/Parallel) you get 48V (Power) System that provides 9.60kWh of Energy.
However, if Cells are 100Ah and configures 3.2V 16/2 you get 51.2V (Power) System that provides 10.24kWh Energy, and the higher Voltage is better for High Amp Equipment Draw.

This is a useful Battery Calculator;

Manufacturers/Retailers should also be telling people how much kWh (Wh) of ENERGY the Battery can Deliver as shown above, as the Amp Hour is Not an indication how much Energy is Stored in your battery Module !
