Overpowering Lead Acid Battery Packs 
Acumentrics’ mission to provide rugged, reliable power for soldiers in theater continues with its new LFP Battery Packs. This new power source offers safe, lightweight, robust energy for fielded and new Rugged-UPS units. 
Crush, fire and bullet penetration testing has been performed to simulate combat situations. Test results indicate that Acumentrics’ LFP Battery Packs remain intact and demonstrated only minimal reactions to these abusive conditions. 

  • System charge and discharge control circuits manage self generated heat 
  • Pack design includes electrical devices that regulate current flow

Acumentrics’ LFP Battery Packs were performance tested in worse case scenarios inherent to battlefield operations. The results indicate a power source with greater cycle life and higher run times than lead acid battery packs.
