My Meshtastic nodes came with 1000 mAh batteries that would only last less that a day. With these 3000 mAh ones they last at least a couple of days before I have to recharge them.

I use these for meshtastic with my heltecs and other devices. They work great and hold charge remarkably longer than other brands.

Overall great. Good price for the bulk. Be aware the jumpers and 2 pin connector are very very small.

well I was cautious when ordering these batteries as some of the reviews said that they didnt meet capacity. I just charged and discharged all 4 of these and they easily pulled more than rated capacity. Time will tell how long they last, but assuming that they will be used of Meshtastic nodes drawing very low current for their entire life, I think they will last years.The price is also super good considering they pull more than full capacity.

These batteries come with the JST 1.25mm connectors from the factory, they work out of the box with the Heltec V3 and will charge just fine, and they hold a charge for a long time if disconnected through a power switch. Be aware that you will need a case that is suitable to fit this battery, the dimensions are (±2mm): 65 * 36 * 10 mm (L*W*H) as written on the official Makerfocus website.

Looks like this might have been a return, the little box had been sloppily taped up.One of the batteries little coupler has been cut off.Fortunately I have someone who can fix it, as I need it faster than I can return it and get one that has not been tampered with.Disappointing.

They look good and are as expected. Not your problem, but I will need to change the connector for my project.
