Good to know

Rad lists semi-integrated models as incompatible with its external batteries, and vice versa.
Radster Road/Trail (15 Ah) and RadRunner Max (14 Ah) are linked only to the pack Rad names for them.
Rad: Safe Shield batteries 'are compatible only with our updated Rad charger' - 'Do not use with older Rad Power Bikes chargers or any third-party or aftermarket chargers.'
Rad: 'Not for use on non-Rad Power Bikes branded ebikes.'
Safe Shield batteries must use the 'updated' Rad charger; Rad's pages do not give a model number to tell updated from older chargers, so buy a current charger from Rad.
RadWagon 5 spec: '48VDC, 2 Amp Rad Power Bikes smart charger', 100-240 V AC input.
