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
Einfach perfekter Service Von der Bestellung bis zur sehr pünktlichen Auslieferung perfekt. Fragen per Mail werden schnell und höflich beantwortet. Die Qualität der mir gelieferten Zellen ist mehr als gut, wenn noch der wirklich gute Preis berücksichtigt wird, beinahe unglaublich
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.
All ok. Equal voltage on all. Batteries are all flat, none of battery is swolen even 1mm.
Schnelle Lieferung, sehr gut verpackt, Kapazität aller Zellen entsprechen den Angaben der mitgelieferten Zertifikate, qualitativ hochwertige Anmutung
