@gus No, this was both unmodified felt and membranes. This also didn't use any membrane frame, just the photopaper compressed between the silicon gaskets. The charge discharge current was set to 40mA. Before charge/discharge I circulated electrolyte for 15 minutes. I also did 2 cycles to 10mAh at 20mA to make sure I wasn't getting any abnormal behavior.
Also, we're planning to use the suction setup from now on, the safety improvements are worth the potential tradeoffs in my opinion.
