Product quality is top par
Product quality is top par. The only downside is the lack of bus communication to the BMS. But if you do not care about that, this product is great. I ordered 4 batteries their 51.2 100ah lipo rack mount (for a total of aprox. 20kwh). All 4 batteries arrived with 53% charge. The packaging was really beefy - Two stout cardboard boxes, with reinforced corners on the inside, enclosing a hard foam package, made to fit the battery. Not a scratch on any of them. The front panel lcd is intuitive and just works off the bat. I don't know what else to say - My prior reservations about ordering for a not insignificant amount of money from a, for me, unknown company are now gone. At least when it comes to vatrer. Almost forgot: The shipping was done internally in the European union. It shipped from somewhere in the southern parts of Germany and arrived here in Denmark after 8 days. They write 5-7 business days, but the shipping company misplaced it during transit, which is quite out of vatrer's control. All'n'all I am one happy camper.
