2017 New Lithium Battery 12V 300AH vechicle battery




TOPBAND Lithium Iron Phosphate (LiFePO4) vehicle battery is the ultimate in weight and size versus power technology. we design this battery mainly replacement for your Lead-acid battery and will require no change to your existing system. It can be placed that uses a sealed lead acid battery completely,which widely used for deep cycle or energy storrage system replacement lead acid batteries in UPS, Telecom, recreative vehicles, Marine, Solar etc.

LiFePO4 contains no poisonous meterial 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, smaller, have much lower self-discharge, and are environmentally friendly.

TOPBAND Models have a Vehicle 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.

             Every battery packs have compact  the Battery Manage System (BMS), its mainly function are:

  •              Internal over charge protection
  •              Internal over discharge protection
  •              Internal short circuit protection
  •              Internal cells balance
  •              Internal temperature monitor
  •              No presence of toxic  substances



  • Expecting charge/discharge cycles number over 2,000.
  • Self-discharge rate about 2% per month
  • Except 8-10 years of battery life that will reduce your operating cost by half compare with Lead acid batteries.


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




       2 Years Full Replacement Warranty including battery and charger.


This batteries are to be used for energy storage applications and NOT for engine starting applications.Unlimited packs in parallel at 12V
