Tewaycell 48V 300Ah 15Kwh All-in-one Mobile ESS Built-in Hybrid Inverter
I reorganized my batteries from 8s2p to 16s (48V). After one year at work (about 160 charge/discharge) I have done another top balancing. All cells arrive at 100% at the same time - no voltage drift - nothing. Inner resistance like new cells. I've ordered the next 16pc!
Evrything is OK.
Son auténticas céldas de grado A. Las he testeado, podéis ver el vídeo en mi canal de YouTube. TeknotroniK. Muy recomendable.
Die Akkus sind alle in Ordnung und haben keine Beschädigungen. Die Verpackung ist top.
Shipped by DPD, arrived well to Austria with tracking. The packing is excellent, safe. Batteries are very good, charged well equally.
Ich bin mit dem Produkt sehr zufrieden und froh endlich meinen Strom besser nutzen zu können. Ich kann den Akku bis jetzt nur empfehlen und habe ihn auch schon Freunden und Nachbarn angeboten. Kein Zoll, oder sonstige Gebü!
After hesitating for a while between the 2 eve 280k models, I finally ordered the 2023 new eve 280k model, thanks to the seller's suggestion. Good cells. Very satisfied！
Después de dos mese guardadas, fue colocarla y están perfectas.
Great price and really fast delivery. Fully satisfayed.

Why LiFePO4 battery?
The LiFePO4 Batteries offers a lot of benefits over other energy storage solutions. They have a longer lifespan, requiring next to no maintenance once setup. They are regarded as one of the safest batteries, lightweight and have higher charged and discharged efficiency.LiFePO4 cells can last up to 5000 cycles of charging and you can safely use 80% of their storage capacity without any degradation unlike other batteries.These batteries come with high power density which means they are relatively light and small in size with higher usable storage capacity. They have a faster-charging capability and better discharge rates make them a great choice motorhomes, caravans, 4WD’s, boats and Off-Grid Living.
MORE ENVIRONMENTALLY FRIENDLY
As LiFePO4 batteries don't use rare or toxic metals and because they last longer they are considered to be more environmentally friendly than other battery technologies.
LESS WEIGHT
Put simply, LiFePO4 cells can store more energy with less weight over other energy storage technologies. This makes them ideal for Caravans, Motorhomes or marine applications.
LONGER LIFE WITH HIGHER CHARGE CYCLES
LiFePO4 Batteries have more charge cycles than other batteries it means your batteries will last longer saving you money on replacement costs.
NO BATTERY MEMORY EFFECT
Battery Memory effect is when the storage capacity of a battery reduces each time the battery cycles through being charged and then discharged. Unlike Nickel-Cadmium and Nickel–metal Hydride batteries, LiFePO4 cells maintain their storage capacity over time.
MORE SAFER
Unlike other Lithium batteries, LiFePO4 cells are different as they contain phosphate crystals and therefore are unlikely to deteriorate or become unstable when overcharged. It means they are far less likely to explode or catch fire unexpectedly.
HIGHER CHARGING / DISCHARGE RATES
LiFePO4 batteries are more flexible with how quickly you can use the energy stored while reducing the amount of time to replenish the energy stored. Perfect if you're storing energy harvested from solar or wind.
