RMBEV EZ Swap Battery Case 2 is the later-model removable battery case for RMB Multi-Point and Protean scooters. It reduces scooter weight for lifting and lets active users swap a drained pack for a charged one to keep moving during warehouse shifts, rentals, RV trips, events, or long rides. Specify whether you have a single-port or dual-port pack. Batteries are not included. Contact RMB EV if you are unsure whether you need version 1 or version 2.
