Prototyping and Engineering Tips from Robogears:

Use a regulated 5V USB adapter capable of supplying at least 2A for optimal charging performance.
Ensure the battery pack is configured as 2 cells in series (2S) before connecting the module.
For battery packs without an integrated protection circuit, use a dedicated 2S BMS to provide cell balancing and protection.
Observe correct battery polarity before connecting the battery to avoid damage to the charger module.

Package Includes:

1 × 2S 8.4V 2A Type-C Lithium Battery Charger Module

Disclaimer:

This module is intended for charging 2S (7.4V nominal, 8.4V full-charge) lithium battery packs only. It is not compatible with 1S, 3S, or higher-voltage battery packs. For maximum safety and battery longevity, use battery packs equipped with an appropriate 2S Battery Management System (BMS).
