California-based Yoshino Technology has developed portable batteries using solid-state Li-NCM cell technology. The four variants come with power outputs of 330 W, 660 W, 2,000 W, and 4,000 W.
Yoshino's 4,000 W solid-state lithium-ion battery
US battery manufacturer Yoshino Technology has developed solid-state lithium-ion batteries with outputs ranging from 330 W to 4,000 W. They are designed for home backup, off-grid applications, and powering small industrial machinery.
The system can be used in combination with solar panels. The 4,000 W power station has a peak power of 6000 W and 2,611 Wh of capacity. It can be fully recharged by a 600 W solar panel in 5.5 hours, according to the company. Other charging options include AC, DC, and USB-C inputs.
“These portable power stations are built around a state-of-the-art solid electrolyte in place of the bulky and flammable liquid electrolyte found in traditional lithium-ion batteries, which improves performance and represents a giant leap forward for battery technology,” Yoshino said in a statement. “Higher energy density means the same amount of power fits into a smaller, lighter package – up to half the weight per watt compared to traditional lithium-ion batteries.”
The smallest battery measures 25.4 cm x 15.5 cm x 24.1 cm and weighs in at 4.58 kg. The largest one measures 54.3 cm x 25.9 cm x 23.8 cm and weighs 24.99 kg. They can reportedly run for 2,500 cycles to 80% capacity.
The 2,000 W and 4,000 W models feature uninterruptible power supply (UPS) when plugged into wall sockets. Yoshino is selling the products starting at $349 retail. They feature a 36-month warranty.
The solution includes a mobile app to monitor charge level, battery health, and connected devices. The entire product range will be available from May.

I don’t get it. Solid state batteries are supposed to be more energy dense, resulting in smaller, lighter batteries, as well as possess a longer recycle life.
Yet to replace a 3 Powerwall installation, one would need 15 of the 4000 watt models- the total weight is 50 lbs more than the 3 Powerwalls.
Also, the 2500 cycle guarantee pails in comparison to Tesla Powerwall’s 5000 cycle warranty, or their Powerwall 2’s unlimited 10 year warranty.
Each 4kw unit has to have a 4kw inverter and charging hardware. It also has to be in a portable protected assembly. That’s where the extra weight goes
The tesla power wall has a built in grid tied inverter, so… not where extra weight is…
Each of these has an inverter.
The powerwall has one inverter for the whole bank
“The 4000 watt station has 2611wh of capacity and weighs 24.99kg with 2500 cycles @ 80%”…doesnt compare favourably with the seemingly much cheaper,lighter and inherently safe lifepo4…des it?
It sounds like these are Lithium gel solid state batteries based on the low performance characteristics stated here.
These appear to be complete “power stations”, with the charging system, and inverter etc included. Naturally it would weigh more than a battery alone.
Checking out the website, and specs, they seem to be similar to other portable batteries in power density.
Unless these are cheaper, Yoshino just looks likes an “also played”.
Confused. What does it mean that it has 4000 watts output? Is that 110 Volts? ie: Does it have an inverter built in that produces 4000 watts at 110 volts?
Also the 2611 w/hr capacity. Is that 12 volt? 24 volts? or ?
Although it doesn’t state here the output voltage, the output wattage is independent of voltage. Watts is a product of volts and amps. So 4000 watts @ 12 volts would require an output of over 300 amps (highly unlikely) and 4000 watts @ 120 volts would require a much more reasonable 33 amps (also possible, about 17 amps @ 240 volts)
Hi, I’ve asked the company, they said it’s 4000 W at 120 V.
What is the difference between this unit and a high capacity rechargeable 12 v car battery and using an inverter? The cost is much less.
