Waveshare Solar Power Manager C

Description

Safety Cautions:

1. Li-ion and Li-po batteries are highly unstable and may lead to fires, personal injury, or property damage if not properly recharged or used.
2. Avoid reversing the polarity when recharging or discharging the battery, and refrain from using inferior charger charging panels for recharging.
3. Do not mix old batteries with new ones, and avoid combining batteries of different brands.
4. When purchasing lithium batteries, ensure that the battery specifications are compatible with the expansion board. Choose batteries from reputable manufacturers and verify their stability and safety through aging tests.
5. Lithium batteries have a limited cycle life and degrade over time. Replace them with new ones when they reach their maximum cycle life or after two years of use, whichever comes first.
6. Handle and store the batteries carefully, keeping them away from flammable or explosive materials, children, and potential safety hazards caused by improper storage.

Features:

The Solar Power Manager C is compatible with general 6V-24V solar panels. It is capable of recharging 18650 rechargeable Li-ion batteries through solar panels or USB Type-C connection, providing a regulated output of 5V/3A with support for multiple protocols, including PD, QC, FCP, and PE. The module features MPPT (Maximum Power Point Tracking) function and multiple protection circuits, ensuring high efficiency, stability, and safety. It is ideal for solar-powered, low-power IoT, and other environmental protection projects.
