A Clear Guide to Our Lithium Battery Wire Sequence
Use this guide to choose a connector and match the battery’s wire order to your device before you place an order.
Connector options and photos
On the battery product page, open Change connector to and select the connector that matches your device. Select any image below to enlarge it. Use the photos to identify the housing, then use the wiring diagrams below to check the pin order.
Two-pin wiring without NTC
Hold the connector with the metal contacts facing you, contacts up and wires down. Read the positions from left to right. In the product configurator, choose Standard or Reversed to match your device.
BAT+ / BAT−
BAT− / BAT+
Red is battery positive (BAT+) and black is battery negative (BAT−). If you select Bare wire (no connector), the connector polarity selector is hidden.
Add NTC and set the three-pin wire order
The NTC is a temperature-sensing lead. With a connector fitted, the configurator shows a 3-pin wiring preview. The default Standard order places NTC in the middle.
BAT+ / NTC / BAT−
NTC / BAT+ / BAT−
- Select your connector and choose Yes, add NTC under Add NTC.
- Read the preview from left to right with the metal contacts facing you, contacts up and wires down.
- Drag a pin to its new position, or click or tap the pin and then select the position where you want it to go. For example, select the middle NTC pin and then the left position to set NTC / BAT+ / BAT−.
- Check all three positions against your device’s pinout before you add the battery to your cart. The selected left-to-right order is saved with your order.
The default NTC is 10 kΩ at 25°C (B25/50 = 3435 K, ±1%). If you select bare wire, the three-pin connector preview is hidden.
Check the pinout before connecting
Using the wrong polarity can damage the battery and device and create a safety hazard. Confirm BAT+, BAT− and, where fitted, NTC against your device’s pinout before connecting. If you are unsure, contact our customer support team for assistance.
