The Turnigy nano-tech single cell 1200mAh (9210000034) is discontinued

For the production of very fast charging e-bike batteries, I need special batteries:
1. High capacity per kg, at least 170Wh/kg
2. Allowed charge rate of 3C

The Turnigy nano-tech 1200mAh ID: 9210000034 meet these requirements, but now it is discontinued. When will it come back into production?
