@scootertherapy, sorry to hear about your bad experience with this Chinese company.My writing NSR and off topic, for I had quite a contrary contact with:
Dongguan Yingfei Electronic Technology Co., Ltd.
..where I ordered two 200Ah LifePo4 accus for my boat to replace 7 year old gel batteries.
The company contacted me via email after my order was placed and asked what appliance it would be, how I would charge those accus and what kind of connectors I wanted to have.
Accus came within 10 days, free delivery, with chargers, built in digital display, aviation sockets, etc.
All in all, a satisfying deal.
