Works well for LoRa boards. I put two in parallel with a charging board for 2000mAH in a tiny space.

Excellent IoT batteries
I purchased these for my Meshtastic builds. I am using them to power a variety of ESP32-S3 powered devices for Meshtastic. Nearly all are solar charged and with a small 2"x3" 60mw solar panel. The build quality has been excellent and on par with what I see from major hobby RC manufacturers. I have since purchased 3 more sets of different capacities for other projects.

Great for Meshtastic Heltec V3 in a 3d printed case
These are great for the meshtastic V3. Keep the devices powered for a hours and seamlessly work after being plugged in. Very happy with this purchase.

10.8mm thick
Works well w/ Heltec Lora32 V3, but pack is 10.8mm thick (not 8.5mm thick as advertised) and will not fit in cases that require a thinner battery such as the muziWORKS H1.

Works well with the Heltec V3 board
Hot glue one of these to the back case of TonyG's Heltec V3 mini case and you're good to go.

Great set of batteries.
I've had no problems with these batteries. Right now all four are in use on my various boards. But note that these 3.7 V LIPO batteries plug into Female JST 1.25 mm connectors. Two the the four batteries I purchased I had to cut off the 1.25 mm male JST connectors and replace with 2.0 mm JST connectors so I could use them to power my LilyPad Arduino USB + boards. LilyPad boards have the ability to charge these batteries, and once charged, these batteries can power the LilyPad boards for hours.

Appear to have the claimed
I just ran all four of these through three full charge-discharge cycles and capacity is as claimed, with two of them even testing >1100mah. This was with a 0.5A charge and discharge current, and 3.0V LV cutoff on an iCharger 4010. Keep in mind these are not rated for any high current application and do have a small connector. Longevity remains to be seen but I am happy with them so far.

Works With Haltech LORA Boards
This battery is terminated such that it directly plugs into Haltech LORA cards (e.g. V2).Basically they work with zero issues and appear to be high quality.
