[0003] High rate lead -acid batteries have higher energy density and higher charging efficiency, and can provide a large amount of electric energy in a short time, and are suitable for occasions requiring a large amount of energy at a moment. High rate lead -acid batteries improve the large current short time discharge efficiency by improving the transmission of electrolyte, the heat resistance of battery current guide and the loss of voltage drop. Specific measures include thinning the thickness of the plate, increasing the concentration of the electrolyte, increasing the porosity of the lead paste, reducing the apparent density of the lead paste and assembling pressure. Limited by the above characteristics of high rate battery, the total energy storage is relatively limited, when the required battery capacity of the working environment is large, multiple batteries are often used in parallel, or each battery is used as a single unit and modularly packaged in a battery whole. In the prior art, the conventional packaging structure is not compact enough, and the disassembly and assembly are relatively cumbersome and complex. SUMMARY

[0007] Preferably, several snap-fit ​​shells are arranged in a straight line with gaps between adjacent snap-fit ​​shells.

[0008] Preferably, there are two grilles, which are located on the front and rear sides of the complete outer shell, respectively.

[0009] Preferably, the fixing plate and the end cap located on the lower side are an integral structure, the elongated hole is only provided on the end cap located on the upper side, and the elongated groove is only provided on the upper part of the fixing plate.

[0010] Preferably, the two end edges of the elongated hole and the two end edges of the elongated groove are both arcs.

The grille serves as a ventilation and heat dissipation unit. The elongated hole on the end cap aligns with the elongated groove at the end of the fixing plate, and the slider is embedded in the elongated hole and groove. Since the insert rod on the side of the slider slides with the end cap, and a spring connects the slider and the end cap, when the slider is pulled by hand through the finger groove, it can be pulled to one end of the elongated hole and groove. When not pulled, the slider will return to the other end of the elongated hole and groove under the action of the spring. At this time, the slot on the slider engages with the protrusion in the elongated groove, locking the slider there and thus securing the end cap. The flange on the end cap and the groove on the housing engage with each other to assemble the end cap and the housing. The snap-fit ​​shell on the end cap secures the battery.

[0014] This invention provides a high-rate lead-acid battery packaging structure. This packaging structure allows for easy assembly and disassembly, and the assembly structure is compact while providing heat dissipation channels, making it suitable for the centralized packaging of multiple batteries.
