SAVE on extreme power cells with our new G3 LITHIUM CELL 18S MODULE. Each module contains x18 G3 cells in 18s configuration.

3.6V 5Ah lithium cells, comparable to CMAX cells, with the G3 terminals being ~1/8" shorter. The G3 cells are more affordable when you buy them as 18S modules!  CELL SPACERS ARE INCLUDED. Some disassembly required.

Module is fairly easy to disassemble, removal of screws with basic tools. Going fast, get yours while they last!
