Maximum available battery length is about 260mm but unfortunately, most of 26650 cells are longer than 65mm.What are the chances that 4x26650 will fit the 5x26500? Simple arithmetic tells me that 4x26650 would be 260mm long, 10 mm longer than 5x26500 mm. Will the tail spring accomodate this extra 10mm with the towerless switch listed in the first post? .
Towerless switch is a tower removed M*g stock switch.Additionally, what are the technical specs for the "towerless switch?" Is it a stock mag switch with the tower removed or is it a custom high current switch set up?
