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 over-discharge, etc.), a large amount of gas quickly gathered inside the battery cell can be discharged through the explosion-proof valve to improve safety.
