U-Charge® RT is perfect for lower voltage applications where excellent run time and intrinsic safety is a pre requisite.
Offering a simple replacement for lead-acid batteries the Lithium Iron Magnesium Phosphate RT series incorporates built-in automatic protection and does not require an external battery management system for optimum usage.

Considerable return on investment is easily achievable with twice the run-time and a weight saving approximately double that of similar sized lead-acid modules.

U-Charge® RT offers a 12 Volt scalable, modular approach, packaged in standard lead acid BCI format sizes suited for a huge variety of applications.
Valence Technology's integrated solutions allow customers to differentiate themselves from competitors by bringing value propositions into their product range.

• Built-in automatic protection for over-charge, over- discharge and over-temperature conditions
• No battery management system required
• Series connection up to four (4) batteries (48 V)
• Internal cell balancing
• LED battery status indicator
• Maintenance-free Rugged mechanical design – dust and water resistant to IP56 standards, flame retardant plastics
• Thousands of cycles, under normal conditions

• Optional battery discharge indicator ( U-BDI ) for SOC display and fault indication

In terms of cycling performance Valence lithium iron magnesium phosphate cathode materials display 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.

• U-Charge® Discharge Performance @ 23^oC
• U-Charge® Life Cycle Performance
• U-Charge® Temperature Performance
• U-Charge® Charge Performance

U-Charge RT® Peripherals ensure optimum performance, monitoring and control of 12V Lithium Iron Magnesium Phosphate battery modules.

• Battery Discharge Indicator

The Battery Discharge Indicator (BDI) provides a simple and elegant solution for display of basic information for the RT battery modules. The BDI can be used with up to 4 RT battery modules connected in series.

• Diagnostics Kit

The module Diagnostics ToolKit includes an RS485 to USB converter which enables a battery module to communicate directly with a PC without the need for a battery management system.

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.

Compared LiFeMgPO4 Nickel Metal Hydride (NiMH) suffers from:

• Poor charge retention
• Memory effect
• Higher cost 

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

• 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.
