Working well for me a month after purchase & many battery cycles. Can't beat getting for of these for the prixe. I'm using these on my Spedix Rex80 HD (see pic). Not sure why there is a JST plug, I'd bet most are using the xt30 & balance plug, Banggood tell Uruav they don't need to put that old style connector on these batteries.

Perfect batteries, too bad because I had not noticed the connector other than my quad...

Batterie perfette, peccato perché non avevo notato il connettore diverso dal mio quad...
