I have exactly the same problem, and the same experience with 3rd gen module. Did you manage to purchase 2nd gen module? I also sent message to DMPstar, but he didn't reply.
I'm looking to but 2, or better 4 modules (3.8V) if possible, to have some spares for the future.
I will appreciate any help.
