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.
1.Long life, large capacity and good shock resistance
2.Low self-discharge and good discharge performance at low temperature
3.Strong charging acceptance and quick-charging capability
4.Strong over-discharge resistance and charge retention
5.Maintenance-free and no acid or water for maintenance in usage
6.Excellent large current discharge performance, and have obvious advantages in startup and climbing
7. High temperature performance
8. Environmental friendly
9. Lighter weight smaller size
10.Most safe no explosion no fire
