Description ▼
The 3.7V 3000mAh 103665 LiPo Battery w/ JST 1.25 Connector is a higher-capacity option for Meshtastic nodes, Heltec and LILYGO boards, Arduino projects, and other 3.7V devices that have room for a larger cell. It is about 65 x 36 x 10 mm, so it is larger than the 2000mAh 103450 battery and is not a drop-in replacement for slim cases built around the smaller cell. Red is positive (+) and black is negative (-). Always check polarity before connecting, because JST 1.25 polarity can vary between brands.
KEY FEATURES
- 3000mAh (11.1Wh) capacity for longer runtime than the 2000mAh 103450 cell
- 3.7V 1S LiPo with a Micro JST 1.25mm 2-pin (SH1.25) connector
- About 65 x 36 x 10 mm (103665)
- Dual protection board
- 1C discharge rate; recommended charge current 0.4A (max 2A)
- Polarity marked: red = +, black = -
- Best for bare boards or roomier enclosures, such as the T-Deck, larger Heltec V3/V4 cases, and some E290 3000mAh cases

What's Included
- (1) 3.7V 3000mAh 103665 LiPo battery with JST 1.25 connector
NOTES
- This cell is larger than the 2000mAh 103450 battery. It is not a drop-in replacement for slim cases built for 103450 cells, including the Heltec Wireless Tracker V2, Vision Master E213, and Wireless Paper slim cases, and the official T114 shell.
- It is best for bare boards or roomier enclosures, such as the T-Deck, larger Heltec V3/V4 cases, and some E290 cases made for 3000mAh cells.
- For slim cases, use the 2000mAh 103450 LiPo battery.
- Always check polarity before connecting. JST 1.25 polarity varies between brands. Red = +, black = -. Reversed polarity can damage the board or the battery.
- This battery is not for the ODROID-GO, which uses a Molex 51021 connector.
- Lithium batteries ship by ground service only.
