The purpose of the utility model is to provide a battery that is easy to carry, easy to install, replace and maintain, has a strong battery life, can be continuously discharged with a large current, has high safety, small size, light weight, good water resistance, anti-reverse connection and charge indicator functions. A small outdoor backup power supply.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a small outdoor backup power supply, including a battery case covered with a battery cover. There are aviation plug fixing holes and fixing screw holes on the battery shell, waterproof and anti-reverse connection aviation plugs are installed at the fixed installation holes of the aviation plugs, and connection terminals are designed on the waterproof and anti-reverse connection aviation plugs. And the spring washer, the other side of the connection terminal is designed with an anti-reverse connection groove, and the head of the connection terminal is covered with a waterproof cover.

In this structure, the positive electrodes of the cells are all pasted with barley paper, and the cells are connected by series-parallel nickel sheet spot welding.

In this structure, the battery cover is provided with a stainless steel movable handle fixed installation hole and a connection port of a waterproof power display board, the inside of the battery cover is provided with fixing screws and nuts, and a stainless steel movable handle is installed at the fixed installation hole of the stainless steel movable handle , a waterproof and electricity-proof display panel is installed at the connection port of the waterproof electricity display panel, a touch switch and an LED indicator light are designed on the waterproof and electricity-proof display panel, and a waterproof film is pasted on the touch switch and the LED indicator light.

In this structure, the LED indicator lights are evenly distributed.

The advantages and effects of the utility model are: because the battery cover and the battery shell of the utility model are fastened by screws to facilitate installation and disassembly; the battery shell is equipped with a waterproof anti-reversed aviation plug; The display board is fixed on the battery cover; the battery cover and the battery shell are made of aluminum alloy and painted; so the utility model has the advantages of ingenious design, small overall size, light weight, reasonable and flexible internal cell connection structure, large capacity, and large capacity. Current continuous charging and discharging, high safety performance, anti-reverse connection and charge display function, convenient operation and strong maintainability.
