Company Information


TOPBAND Lithium Iron Phosphate (LiFePO4) battery is the ultimate in weight versus power technology. This is a drop in replacement for your Lead-acid battery and will require no change to your existing system. It can be placed in anything that uses a sealed lead acid battery . Used for deep cycle or energy storrage replacement lead acid batteries in UPS, Telecom, Marine, Solar etc.

LiFePO4 contains no poisonous lead, no acid, and does not create gasses during charge, as traditional Lead-Acid batteries do. Compared to lead-acid, Lithium Iron Phosphate batteries are also extremely light, have much lower self-discharge, do not sulfate, and are environmentally friendly.

TOPBAND Models have a Battery Management System (BMS). BMS monitors the key operational parameters of each cell during charging and discharging such as voltages, currents and internal temperatures.

There are three main objectives common to all Battery Management Systems (BMS) are:


• Protect the cells or the battery from damage from overcharging or discharging too low.
• Prolong the life of the battery with cell balancing.
• Maintain the battery in a safe operating state.

Because of its light weight, safety, excellent thermal stability, good electrochemical properties and high specific capacity is this application of the material very well received.

Dimensions equal to the standard battery for direct replace.

The "SmartEnergy" energy storage battery is intended to be used as a direct replacement for lead acid batteries used in energy storage systems.  It is best for the "SmartEnergy" battery not to be trickle charged but to use advance chargers that turns OFF charging current when the battery is completely charged at 14.6V.  TOPBAND sells "Smart" chargers for lithium batteries.  Using lead acid chargers that charges up to 16V, along with leaving them ON, will damage the Lithium battery over extended time.


       • Expected number of charge cycles over 2,000.  

       • Self-discharge rate only 2% per month.

       • Expect 8-10 years of battery life that will reduce your operating cost by half  
          compared to lead acid.
2 Year Full Replacement Warranty
