Cell
The lithium battery system adopts 3.2V 150Ah high energy lithium iron phosphate cell with square aluminum shell design, which reduces the possibility of internal damage caused by mechanical damage to the surface of the cell and improves the safety performance of the product. The battery is equipped with a thin-film explosion-proof valve to ensure that in any extreme circumstances (such as internal short circuit, battery overcharge and overdischarge, etc.), a large amount of gas rapidly gathered in the battery can be discharged through the anti-riot valve to improve safety.
