Application Scenarios
Electric Bicycles: Provides reliable protection for lithium battery
packs in electric bicycles, ensuring battery safety during riding,
extending battery replacement cycles, and reducing operating costs.
**Drones:** Protects lithium batteries from various abnormal situations during drone flight, ensuring flight stability and safety, and preventing crashes caused by battery problems.
**Energy Storage Equipment:** Used in home energy storage, solar energy storage, and other systems, it effectively protects lithium battery packs, improving the reliability and lifespan of the energy storage system, and ensuring stable energy storage and supply.
**Instructions for Use:**
**Pre-installation Preparation:** Confirm that the specifications
of the lithium battery pack match the applicable scope of the
protection board. Check the protection board for any damage,
looseness, or detachment of components.
**Battery Pack Connection:** Connect the positive and negative terminals of the lithium battery pack and the balance wires between each cell correctly according to the markings on the protection board, ensuring a secure connection and avoiding loose connections.
**Function Testing:** After connection, use professional battery testing equipment to test the various protection functions of the protection board, ensuring that overcharge, over-discharge, overcurrent, and short-circuit protection functions are normal.
Installation into Equipment: Correctly install the lithium battery pack with the protection board installed into the corresponding equipment, ensuring a stable installation position to prevent shaking or collisions during equipment use.
Precautions: During installation, strictly follow the operating procedures to avoid damage to the protection board or short circuits in the battery due to incorrect connections.
Regularly check the operating status of the protection board and the battery pack connections. If any abnormalities are found, stop use immediately and perform repairs.
Avoid contact between the protection board and liquids such as water and oil to prevent corrosion and short circuits.
Do not disassemble or modify the protection board yourself, as this may affect its performance and safety.

Wiring precautions:
1. Installing the protective board requires a certain amount of
technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad
position to the total negative terminal of the battery (the B- wire
should be soldered to a short and thick wire) and solder the wired
terminal to the battery pack first, and then insert the protective
plate.
3. The connection between the battery terminal B- and the
protection board terminal B- should be short and thick, otherwise
it will cause the protection board to charge and discharge in
advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
