Lithium ion Charger 18650 Polymer Type C to 2S 8.4V 1A Booster Module

The Lithium ion Charger 18650 Type C to 2S booster module charges a two-cell (2S) lithium battery pack from a standard 5 V USB supply. It boosts the USB Type-C input up to the 8.4 V needed to fully charge two 18650 Li-ion or Li-polymer cells in series, with a 1 A current rating, so you can recharge robot, speaker and portable project batteries from a phone charger.

Lithium ion Charger 18650 Specifications

Lithium ion Charger 18650 Applications

• Charging 2S 18650 packs for robots and RC projects
• Adding USB-C charging to portable speakers and gadgets
• Battery-powered Arduino and ESP32 builds that run on 7.4 V
• Replacing a dedicated 8.4 V charger on the workbench

What's in the Box

• 1 × Type-C to 2S 8.4 V 1 A lithium charger booster module

Tip: Use this module only with 2S packs; it is not suitable for single cells or 3S packs. Pair it with a 2S protection (BMS) board and matched cells, and use a good 5 V USB adapter, because a boost charger draws more current from its input than it delivers to the battery.
