The Scepter ecosystem

Powering African mobility and businesses with connected clean energy

Automated, self-service battery swapping for approved electric two-wheelers, with tricycles joining after separate validation — and solar-first hybrid energy behind every station. Our first stations are piloting in Lagos.

Service today: Lagos (pilot) · Abuja coming soon

Transparent pricing
Energy and battery access priced separately, shown before you pay.
Safety first
Every pack is checked on return; damaged or hot packs never go back out.
Solar-first stations
Stations designed to run on solar first, then storage and grid.

How the network works

From sign-up to swap in four steps

  1. 1

    Join the pilot

    Sign up with your phone number, register your vehicle and choose pay-as-you-go or a monthly plan.

  2. 2

    Find a station

    See operating stations and, where telemetry is reliable, how many charged packs are ready.

  3. 3

    Swap in minutes

    Self-service, no queue for an attendant: scan the station QR in the app, put your battery in the door that opens, and take the charged one from the next.

  4. 4

    Clear receipt

    Pay for the energy delivered plus a separate battery access fee. Every receipt shows both.

Scepter Grid

Hybrid energy behind every station

Stations charge from the cheapest reliable source, measured not assumed. Solar comes first, storage covers peaks and outages, the grid fills gaps, and a fuel cell is added only where it is justified and approved.
  1. Solar 1

    First choice when the sun is up

  2. Stationary storage 2

    Covers evening peaks and outages

  3. Grid 3

    Fills gaps at the best measured cost

  4. Fuel cell Optional

    Only where justified and approved

Station

Smart energy controller

Chooses the source by measured cost and reliability, then charges batteries in the SwapStation cabinet. Metered so energy cost per delivered kWh is known.

Priority: solar, then stationary storage, then grid; a fuel cell only where justified.

Commercial energy-as-a-service is coming soon. Hydrogen stays a separate, controlled future pilot.

Stations
