hm, that doesnt sound very special to me. on paper its pretty much 100% like my latest 10S4P battery (37V, 12Ah, 80A continuous current) - but for more than twice the money!
not sure how reasonable 80A continuous current with 1000 life cycles is though - but also not sure how reasonable their 60A continuous current with 1000 life cycles is. dont know anything about that NMC chemistry
