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
Happy with purchase and would recommend. Unit arrived a month early (ordered end of march, expected start of june, showed up start of may) though i didn't know it was coming until fedex showed up at my door.
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
Arrived in 3 days, good communication with the seller, batteries are very high quality 16x EVA
Alles in Ordnung. Die Zellen sind in sehr gutem Zustand, nicht beschädigt. Gut verpackt. Verbinder (Busbars) wurden beigelegt. Sehr zu empfehlen.
