Electric Core
Lithium battery system using 3.2V 280Ah high energy type lithium iron phosphate core, square aluminum shell design, reduces the possibility of damage to the surface of the core due to mechanical damage and of damage to the inside of the core, improves the safety performance of the product. The battery cells are installed with a film-shaped explosion-proof valve to ensure that in any extreme case (such as internal short circuit, battery overcharge and overdischarge, etc.), a large amount of gas quickly gathered inside the battery cell can be discharged through the explosion-proof valve to improve safety.
Module
The battery module consists of 12 3.2V 280Ah lithium iron phosphate cell, 1 parallel and 12 strings (12S1P) to form a 38.4V 280Ah battery module. The module has a built-in BMU system, which collects the voltage and temperature of each cell and manages the equalization of cells to ensure the normal operation of the whole module safely and efficiently.
