When to Choose a Lithium PMA

Lightweight lithium battery-powered PMAs are ideal when the device needs to be folded or carried frequently. Common use cases include:

  • Transporting the PMA by car
  • Bringing the PMA on a plane
  • Carrying the PMA over high obstacles such as a flight of steps

When to Choose an SLA PMA

If weight is not a key concern, sealed lead-acid (SLA) battery-powered PMAs may be the better option. Key advantages include:

  • Much lower fire risk compared with lithium PMAs
  • More stability due to heavier weight and a lower centre of gravity
  • Greater power and capability when handling obstacles such as low kerbs and MRT train-to-platform gaps
