Battery capacity is very large, can reach more than 295ah, after 15 days of transport received the battery is very good, no damage, I am very satisfied
The package arrived after about 5 days. All cells look good and got correct parameters. Happy to have it, will order more after some long term testing
Batterie arrivate e tutte alla stessa tensione ottima comunicazione con il venditore per adesso perfetto!!!
The batteries arrived quickly, well packaged, and all 16 cells were at the same voltage — 3.29V. All of them are in perfect shape. Now I'm doing the top balancing, and then I will assemble the two batteries.
Schnelle Lieferung und tolle Qualität

Ok.
Battery is strong and consistent, no voltage drop issues so far.
Definitely a premium product, would buy again without hesitation.
Perfect for building my own 12V / 24V battery bank.
Super happy with the performance, exactly what I needed for my DIY system.
