U-Charge® XP Lithium Iron Magnesium Phosphate Battery Modules

Safe lithium iron magnesium phosphate (LiFeMgPO4) energy storage solutions in standard BCI lead-acid battery sizes for a wide variety of applications.

U-Charge® XP is a range of 12, 18 & 36 volt Lithium Iron Magnesium Phosphate battery modules, offering intrinsic safety with twice the run-time and less than half the weight of similar sized lead-acid battery modules.

Comparing U-Charge® LiFeMgPO4 to other chemistries

U-Charge® XP Lithium Iron Magnesium Phosphate (LiFeMgPO4) modules have considerably greater energy density making them particularly suitable for numerous applications. LiFeMgPO4 is considered safer, less toxic, and more energy efficient with significantly longer cycle life.

Compared to Lead Acid

Commonly used in starter batteries for internal combustion engine (ICE) vehicles Lead Acid is normally a low-cost secondary battery, composed of a Lead-dioxide cathode, a sponge metallic Lead anode and a Sulphuric acid solution electrolyte. The heavy metal element makes Lead Acid batteries toxic and improper disposal can be hazardous to the environment.

Disadvantages of Lead Acid batteries include

  • Failure between several hundred and 2,000 cycles
    Comparatively low energy density,
    Long charge time
    Careful maintenance requirements

Compared to Nickel Cadmium (NiCd)

Disadvantages include:

  • High rate of self-discharge at high temperature.
  • Cadmium is highly toxic
  • Use in batteries is controlled
  • Environmental recycling issues
  • Memory effect is one of the biggest disadvantages to using NiCd.

Compare LiFeMgPO4 to Nickel Metal Hydride (NiMH) suffers from:

  • Poor charge retention
  • Memory effect
  • Higher cost

Sodium (Na-NiCl2) so-called zebra battery.

When not in use zebra batteries typically require to be left on charge, in order to be ready for use when needed.

If shut down,the reheating process lasts 24 hours, and then a normal charge process of 6-8 hours is required for a full charge.
Inefficiency due to energy consumption when not in use.

  • 2800 cycles at 100% DOD

  • Exceptional voltage stability

  • Standard voltage range from 12V - 700V

  • Maintenance free

  • Inter module balancing

  • Can be charged using most standard lead acid chargers

  • Communication of monitored data via Battery Management System (BMS)

  • Rugged mechanical design

  • Flame retardant plastics

  • LED battery status indicator

  • Carrying Straps (U24, U27, UEV)

  • Manufactured in standard BCI sizes

In terms of cycling performance U-Charge® XP displays excellent characteristics.

Current cycling demonstrates minimal linear fade reaching over two thousand eight hundred full one hundred percent charge and discharge cycles to eighty percent depth of discharge.
