LORDWORLD 4S Type-C 16.8V Boost Li-Ion Charger Module 4A

SKU CH-TJW3-YP0R5

Boosts 3–6 V input to 16.8 V for four-cell lithium-ion packs at up to 4 A via USB-C

  • Charges 4S Li-Ion packs to 16.8V via USB-C
  • Accepts 3-6V DC input for flexible power sources
  • Delivers up to 4A charging current for fast replenishment
  • Boost converter topology steps up voltage efficiently

4S Li-Ion charger module with Type-C input

This module accepts a DC input between 3 V and 6 V and boosts it to 16.8 V for charging a four-cell polymer lithium-ion pack. It delivers up to 4 A of charge current through a USB Type-C connection. The board is designed for DIY battery projects that need a compact step-up charging solution.

Upgrades from basic linear chargers

Builders who previously relied on non-boost chargers or separate boost converters can consolidate both functions here. The jump is worth it when the available source voltage is below the pack voltage and a single board with Type-C convenience is preferred. It does not suit packs with a different cell count or applications that need a higher input voltage range.

Questions about this item

What input voltage range does the 16.8V boost charger module accept?

The module steps up a DC input between 3 V and 6 V to a 16.8 V charge voltage for a 4S lithium-ion pack.

How do I connect the USB-C port and battery leads without reversing polarity?

Plug the USB-C connector into a 3–6 V source, then solder the B+ and B- pads to the corresponding pack terminals; the silk-screen labels show the correct polarity.
