" Lithium Metal Hydride ? " wtf is that ?

anyways.. C-LiFePO4 40138 cells are 40 x 138 mm ( 40mm diameter.. 138mm long )

5.4 inches long.. but then add the threaded bolts and you get 6.75".

Green " lifebatts " or older stock.. or whatever version of the story you got. No matter.. decent cells but at 158 + shipping.. no charger no bms = 40 $ per cell.

No.

Ping is using flat " foil pouch " type cells. the tabs are soldered/spot welded together.
