The charging module for 3S lithium batteries (12.6 V) with a charging current of 3 A ensures precision up to ±1.0%. Built-in protection features include low input voltage, output short circuit protection, and battery overheating protection. The package includes a temperature sensor for the battery and a self-adhesive radiator that efficiently dissipates heat, prevents overheating, and extends the module's lifespan.


Specifications:

Connection: Connect the battery first, and then you can connect the power to the module. Be extremely careful when connecting, as the module lacks reverse polarity protection!

Module Operation: The module uses a small current for preliminary battery charging, after which it switches to constant current mode. When the battery voltage approaches the maximum, the charging current will gradually decrease, and the module will transition to constant voltage mode. When the current drops to 300mA, the charging cycle ends. If the input power is insufficient for charging or the input voltage is below the battery's charge level, the charging module enters a low-power sleep mode.

The current consumption is less than 15 µA (0.015mA), extending the standby time.

Indication: A red LED indicates the charging process, a green LED indicates that the charging is complete. A flashing red LED signals that the battery is not connected.

Operating Temperature: The module may heat up to 65-75°C during operation. It is recommended to install it at a distance of at least 10mm from the battery.
