...I would suggest checking the 3 T10 screws that face towards the floor. During my setup one fell to the floor. I added some blue thread locker and snugged all three. Unsure of a torque spec but the seems like they would strip threads easy so take it easy if you do this.

See attached for screws to check.

Wondering if anyone has a recommendation for 14500 cells. I have a generic set from eBay but am suspicious of their capacity/reliability. Would like to have another set on hand to try.
