High-Quality Solar LED Street Lights | Queneng

Queneng offers a warranty of 2-5 years on our solar street lights, covering defects in material and workmanship. The warranty duration may vary based on the model and product components.

1) There is no battery leakage problem. The battery does not contain liquid electrolyte and uses colloidal solids;
2) Can be made into a thin battery: with a capacity of 3.6V and 400mAh, its thickness can be as thin as 0.5mm;
3) Batteries can be designed in various shapes;
4) The battery can be bent and deformed: the polymer battery can be bent up to about 900 degrees;
5) Can be made into a single high-voltage battery: a battery with liquid electrolyte can only produce a high-voltage polymer battery by connecting several batteries in series;
6) Since it is liquid-free, it can be combined into multiple layers within a single chip to achieve high voltage;
7) The capacity will be twice that of a lithium-ion battery of the same size.

The APMS system uses intelligent algorithms to automatically charge during the day and discharge at night. The dual-system management mode monitors battery status in real-time and adjusts the charge/discharge mode to ensure optimal efficiency under any condition.

Connecting the two ends of the battery to any conductor will cause an external short circuit. Depending on the battery type, the short circuit may have consequences of different severity. For example: the electrolyte temperature rises, the internal air pressure rises, etc. If the air pressure value exceeds the battery cap's pressure resistance value, the battery will leak. This condition severely damages the battery. If the safety valve fails, it may even cause an explosion. Therefore never short-circuit the battery externally.

New green environmentally friendly batteries refer to a type of high-performance, pollution-free batteries that have been put into use or are being developed in recent years. At present, lithium-ion batteries, metal hydride nickel batteries, mercury-free alkaline zinc-manganese batteries that are being promoted and used, and lithium or lithium-ion plastic batteries, combustion batteries, and electrochemical energy storage supercapacitors that are being developed are all new types. The category of green environmentally friendly batteries. In addition, solar cells that use solar energy for photoelectric conversion have been widely used.
