Good to see progress!
We published a follow up article at Lithium Ion battery storage and transport - E-Surfer about some of the new solutions from Onean, Torque and Lift.
We also experimented with some DIY solutions based on steel boxes and PyroBubbles granulate. See some pictures here …
Just an FYI related to this topic. ZARGES released their BatterySafe™ cases which work well for e-Foil batteries. They have been tested and help significantly with these runaway battery fires. There is more information here on their website.
