This series lithium iron phosphate battery is one of new energy storage 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 low power, limited installation space, restricted load-bearing and long cycle life.
This series 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 and discharging to extend cycle life.
Multiple batteries can connect in parallel for larger capacity and longer power supporting duration requirements.
