Cause of the explosion of the solar container battery compartment

When a solar battery is overcharged, excessive voltage floods the storage unit, leading to excessive heat buildup within. What causes a battery enclosure to explode? The large explosion incidents,in which battery system enclosures are damaged,are due to the deflagration of accumulated flammable gasesgenerated during cell thermal runaways within one or more modules. Battery Types: Different types of solar batteries (Lead-Acid, Lithium-Ion, LiFePO4, NiCd) have unique. The energy storage capacity and charging and discharging time of lithium batteries are much better than other rechargeable batteries at the time, greatly enhancing. I thought "oh, well the whole RV will be burned to the ground cause you can't put out Li fires", so I didn't throw water on it ASAP.
