This portable power pack in development has the following predicted capability at 100 Watts​.

• Between 465 Wh and 2000 Wh of energy, depending on internal configuration. The pack lasts between 2.6 and 11 times longer than the incumbent lithium primary battery.

• The pack is recyclable and has a life of 10 years.

• The pack is compliant with all devices normally powered by a BA5590. It is a direct replacement.

This is a new kind of mobile electrical power system, some people call it 'the electric engine'. MAAPS is CO2-free power system refuelled, not recharged. This would be done by automatic cassette exchange at a vehicle service point, but the range is much longer that for a rechargeable battery (1300Wh/kg) so these exchanges are infrequent.

​

Important key features of MAAPS:

• Starts/stops the chemical reaction on demand

• Keeps the reactive surface clear

• Manages air and electrolyte transfer

• Designed to be refuelled

• Cassette system

• Industrial automatic high speed refuelling

• 1300Wh/kg

• Recyclable

MAAPS-2 has a unique architecture which is designed for very high specific power and energy and has applications in defence, aircraft propulsion and high-power vehicles.

​

Key features include:

• Pliable behaviour

• High voltage/power per square metre

• Long duration of operation

• Recyclable

REX is Metalectriques answer to range anxiety in new electric vehicles. With the ability to be swapped out in 90 seconds, you're left with an additional 300 mile range. With REX being a fuel cell (non rechargeable), it produces 40kWh of power, totally reliant on it's own stable reaction, not a separate power source.

Key features include:

• 90 second swap time

• 300 mile range 

• Long duration of operation

• Recyclable

• ​Minimal weight addition at only 40kg
