Introduction
This series lithium iron phosphate battery is one of new energystorage products developed and produced by
Deye, it can be used to support reliable power for various types of equipment and systems.
This series is especially suitable for application scene of high power,limited installation space, restricted load-
bearing and long cycle life.
This series battery has built-in BMS ( Battery Management System ), which can manage and monitor cells
information including voltage, current and temperature. What’s more, BMS can balance cells charging to extend
cycle life.
Multiple batteries can connect in parallel for larger capacity and longer power supporting duration requirements.
