2. Introduction
The Stack’d Series lithium iron phosphate battery is an energy storage product developed and
produced by HOMEGRID, it can be used to support reliable power for various types of
equipment and systems. The Stack’d Series is especially suitable for applications of high power,
limited installation space, and restricted load-bearing and long cycle life.
The Stack’d Series has a built-in BMS battery management system, which can manage and
monitor cell’s information including voltage, current and temperature. The BMS can also help
extend the cycle life by balancing cells during charging and discharging.
Multiple battery stacks are allowed to be connected in parallel to expand capacity and power to
meet almost any requirement.
2.1. Lithium iron phosphate Battery
The lithium iron phosphate battery (LiFePO4 or LFP) is the safest lithium battery. A single LFP
cell has a nominal voltage of 3.2V. A 48V LFP battery consists of 15 cells connected in series.
LFP is the chemistry of choice for very demanding applications. Some of its features are:
◆Safety- LFP is the safest Li-Ion battery and does not propagate thermal run away.
◆High round trip efficiency.
◆High energy density - More capacity with less weight and volume.
◆High charge and discharge currents - Fast charge and discharges are possible.
◆Flexible charge voltages.
The lithium iron phosphate battery is therefore the chemistry of choice for a range of very
demanding applications.
2.2. Stack’d Series Features
◆The whole module is non-toxic, pollution-free and environment-friendly;
◆Cathode material is made from LiFePO4 for safety, performance, and long cycle life;
◆Battery management system (BMS) has many protection functions including over-discharge,
over-charge, over-current, and high/low temperature;
◆The system will automatically manage charge and discharge state and balance current and
voltage of each cell;
◆Flexible configuration, multiple battery modules can be internal for expanding voltage and
Capacity.
◆Adaptative self-cooling reduced system noise;
◆The module has low self-discharge, up to 6 months without charging, no memory effect,
excellent performance of low discharge;
