4SB Mobility

At 4SB, we are designing and manufacturing a small, swappable battery for electric vehicles. This attaches to the electric vehicles (EV) main battery, topping it up and giving the driver 90 miles of range, available in a 2 minute swap. 4SB’s core activities are the design, manufacture and sale of these EV batteries.

These batteries do not replace EVs main batteries – they complement them. Our swappable batteries connect directly to the main EV battery, via the underside of the EV. Alongside this, 4SB will begin to integrate swap stations in urban areas, replacing existing lanes at traditional fuel stations.
