4S 4A 16.8V Lithium Battery Power Charging Module – Type C

The 4S 4A 16.8V Lithium Battery Power Charging Module – Type C connected in series produce a nominal voltage of 14.8V and reach exactly 16.8V at full charge — that is 4.2V per cell at 100% state of charge. The Power Charging Module handles that charge termination automatically, accepting 5V DC through a Type-C connector and boosting it internally to deliver 4A into the connected 4S pack. Without precise termination at 16.8V, individual cells overcharge beyond 4.2V, causing permanent capacity loss and increasing thermal risk in the pack.

The 4s 4a power charging module takes 5V DC input from any USB-C power bank, laptop port, or 5V wall adapter — one of the most accessible input requirements for a 4S charger at this specification. At 4A charging current, a 4S pack built from standard 18650 cells reaches full charge meaningfully faster than a 1A charger would manage. The 4S Battery Charger Module onboard IC manages both charge current regulation and termination without external components, making it suitable for embedding inside device enclosures.

This module charges 4S packs only. Connecting a 3S or 2S pack to a 16.8V charging circuit will overcharge those cells past their per-cell maximum and damage them permanently. The 18650 Battery Charger Module Type-C suits engineers building custom 4S packs for drones, electric vehicles, and portable power tools. This 4s power charging module working on lithium battery management and build embedded portable power system.
