3.7V 2200mAh Lithium-Ion Battery with 2mm Connector

The 3.7V 2200mAh Lithium-Ion Battery with 2mm Connector is an 18650 Li-Ion cell with a pre-attached cable and 2mm pitch connector rather than bare terminals. A standard 18650 cell has flat or button positive and negative ends that need a spring holder, spot-welded nickel strip, or direct soldering to connect into a circuit. This variant replaces that step the cell comes with a wire lead already attached and terminated in a 2mm pitch connector that plugs directly into a matching header on a PCB or charger module, making battery installation and removal tool-free.

The 3.7 v 18650 battery is the preferred choice for where the battery needs to be disconnected and reconnected regularly bench testing, field-swappable battery designs, and development boards that include a 2mm pitch JST or similar header for single-cell Li-Ion connection. At 2200mAh the cell stores 8.14Wh of energy, running a 200mA load for approximately 11 hours per charge. The 2200mah 18650 battery charges to 4.2V per standard Li-Ion chemistry any single-cell Li-Ion charger module like the TP4056 that accepts a 2mm or compatible connector will charge this cell correctly.

The 18650 rechargeable battery with 2mm connector suits wearable electronics, handheld instrument, and development boards with onboard Li-Ion charge management. Confirm connector polarity against the target board’s header before connecting reversing polarity on a Li-Ion cell connection damages both cell and circuit. Available on StemVolt. This cell is working on connector-ready Li-Ion and portable power projects.
