Flame Retardant 21700 Spacer (2 batteries)

Size Options:

  • 21.2mm - Fits most Samsung, LG, Murata 21700 cells

    21.7mm - Fits most Lishen and other China manufactured cells

    Lishen (LR2170LA) uses 21.2mm spacers. All other Lishen models = 21.7mm

    Many of the spacers on the market currently are not flame retardant. They are made of cheap plastics which means that a battery fire could potentially spread through the spacers to other cells.

    Our spacers are made up of flame retardant plastic.
