The price for the LiFePO4 51.2V/628Ah transportation included, DDP (Delivered Duty Paid) shipping was very, super affordable. As you can see from the photos, after thousands of miles the wooden box was intact. Battery wrapped in a thick layer of spongy plastic. There were the two copper cables for connection to the inverter. Suggestions: 1) ask that they also provide the cable that is used to connect the battery to your PC (USB-RS232 cable); 2) let the vendor know which inverter their battery will be connected to, so they will give you the wired lan cable to make their battery's BMS talk to your inverter; 3) before the battery is shipped have them check that the BMS has actually been programmed for the number of amps you paid for. The next day the engineer on tele-service unlocked the battery to 200Ah. Would I still purchase from BetterESS? Yes, I think so, but first I will have to see how the battery behaves after a year of work.

Die EVE 628Ah Batterie ist eine echte Investition in Zuverlässigkeit. Ich nutze sie für meine Solaranlage zu Hause, und die Leistung ist konstant hoch. Die Kapazität reicht locker für unsere ganzen Geräte, und die Lade- und Entladezyklen funktionieren einwandfrei. Außerdem ist der Kundenservice sehr hilfsbereit bei Fragen. Ich würde sie jederzeit wieder kaufen.
Neatly packaged. Everything arrived in order. All four cell voltages are 3.27 volts. Thank you, seller.
I installed the 48V 10kWh 200Ah All-in-One Sodium-ion Battery in my home solar system, and it has exceeded all my expectations. Setup was very easy, and everything integrates perfectly. The battery provides stable and reliable power even during cloudy days or short outages. The 10kWh capacity is fantastic – I can run all my home appliances for multiple days without worry. The efficiency and build quality seem excellent, and customer support has been very responsive. I highly recommend this system for anyone looking for a dependable, high-performance home energy storage solution.
Diese Batteriezellen haben meine Erwartungen übertroffen. Sie sind brandneu und in einwandfreiem Zustand angekommen. Die Leistung ist stabil und die Zellbalance ist sehr gut. Ich verwende sie in einem Solarspeichersystem und habe keinerlei Probleme festgestellt. Der Verk?ufer war professionell und die Lieferung erfolgte schnell. Insgesamt ein sehr hochwertiges Produkt, das ich gerne weiterempfehle.
