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.

Gute Qualität Werte der Zellen passen auch gut top.
A great seller. I'll buy from them again in the future.
Express delivery in 5 working days!
The batteries arrived within 7 days, production dates from August 2025, original codes, voltages are all equal at 3.291V, and they have balanced perfectly during operation. Highly recommended!
The package arrived even though I did not receive shipping information, so I couldn’t track it. Nevertheless, the product works perfectly and the initial tests are very promising. Highly recommended!
