Collection: Foil Drive Batteries & Chargers

Foil Drive batteries are made for one system each, with one exception: the FM+ 650 runs both the MAX+ and the Fusion (the Fusion with the FM+ Battery Adaptor): the Fusion 860 for the Fusion, the MAX batteries for the Assist MAX, the Slim batteries for the Assist Slim, and the PLUS batteries for the Assist PLUS. Chargers are sold by voltage, 28v, 40v and 43v; each charger listing says which batteries it suits.
