Sentry Batteries - Lithium LiFePO4 Deep Cycle



Sentry Lithium batteries is a premium range using the highest quality Lithium Iron Phosphate (LiFePO4) composition. LiFePO4 has been selected for the Sentry range due to its convenient cell voltage, high energy density, cycle life and most importantly, being one of the safest Lithium technologies available.

With 3.2V per cell, the Sentry Lithium range is ideally suited for replacement of equivalent size SLA with the extra benefits of up to 8 times the cycle life, greater utilisation of available capacity through increased Depth of Discharge (DoD) and fast charging. All of this at close the half the weight makes them ideals for deep cycle and mobility applications.

Feature & Benefits:

  • Greater number of cycles (2500+) along with greater utilisation of available capacity (up to 100% DoD) depth of discharge, means up to 8 times the cycle life of standard SLA technology
  • Lowering you total cost of ownership.
  • Integrated battery management system (BMS)
  • Provides optimum safety and performance.
  • Safe and stable chemistry
  • The use of LiFePO4 along with an integrated BMS reduces the risk of combustion or explosion due the high impact, overcharging or short circuit situations.
  • Higher energy density means Sentry Lithium is close to half the weight of an equivalent SLA making them ideal for mobility and weight critical applications.
  • Extra fast recharge time and can be charged using most standard SLA charger
  • No need to upgrade your existing charging infrastructure.
  • Rugged plastic flame retardant case & cover.
  • UL1642 at cell level.


  • Mobility devices
  • Caravan and camping
  • Solar energy storage
  • UPS and critical power
  • Personal power packs
  • Medical equipment
