High Capacity Pack

Steatite manufacture portable lithium power packs complete with safety electronics, accurate fuel gauge and intelligent charging systems for professional use. In applications which require power to be rapidly deployed we recommend the APU range housed in rugged waterproof cases.

For other applications we recommend our standard building blocks which provide up to 160Ah capacity -x these batteries and safety electronics can be designed into existing enclosures or new cases to suit the application.

Steatite Auxillary Power Units (APUs)

In portable operations the use of large rechargeable lithium battery packs offers significant advantages over convention lead acid systems. A 100Ah lithium battery can weigh half of a lead acid battery pack! With less weight and extended run time the initial benefits are easy to see. Coupled with extraordinary cycle life the lithium rechargeable pack offers real long term benefits to the user.

Whether being used for communications, surveillance or powering CCTV equipment or other remote devices the Steatite APU is regarded by many as the best portable power available.

The Steatite Auxiliary power Unit is designed for the professional user in critical applications where reliability and performance matter. Using rechargeable lithium batteries the APU provides excellent energy density. The pack is used widely by CROPS personnel, technical support units, rapid response units and other authorities who require portable power for electronic equipment. Our units incorporate safety electronics and battery protection and real state of charge LED indication.
