This 3.7V 1800mAh Lithium Polymer (LiPo) rechargeable battery pack provides reliable power for a wide range of devices. Equipped with a standard JST connector, this battery is ready to go for most applications. For use with the Heltec V3, a 1.25 JST connector is required, but we’ve got you covered!
 
Choose the modified battery which includes one of our Reversed Micro JST 1.25SH Female to JST-PH 2.0 Male Battery Adaptors. This special adaptor is custom-modified by us with crossed-over cables on the JST-PH 2.0 side, making it compatible with the Heltec V3.

If opting for the modified version ignore the cable colors as they do not reflect the correct polarity. Instead, refer to the coloured dots on the plastic connector to ensure correct alignment with the polarity of your battery and node.

Fully compatible with the UKSN Project Lora Portable Node Case and the fully built Project Lora Portable Node 868MHz Standard Version, it's designed for seamless installation and reliable performance.
