Technical insight

Product and application details

Solar System

Its ultra-long cycle life ensures reliable energy storage for off-grid solar setups over many years.

Mobile data terminals (MDTs)

The lightweight design reduces vehicle payload while providing stable 12V power for continuous MDT operation.

Emergency vehicle & first responder systems

Long cycle life supports frequent deep discharges from radios without degrading battery health during critical calls.

Trolling motors

High capacity delivers sustained current for trolling motors while keeping total system weight low for boat handling.

Portable traffic signals

Robust cycle life withstands daily charging cycles required for temporary portable traffic signal deployments.

Variable message boards

Lightweight construction eases installation on trucks while 300Ah capacity powers variable message boards for hours.

Radio repeaters

Stable 12V output ensures uninterrupted communication for radio repeaters even during extended grid outages.

Emergency vehicle & first responder systems

Long cycle life supports frequent deep discharges from radios without degrading battery health during critical calls.
