About this item

  • Charging Method: The recommended charging current is 0.6A, the maximum does not exceed 3A. The discharge current is recommended 1.5A, and the maximum does not exceed 3A
  • Overcharge Protection: When charging the battery, when the voltage reaches the highest battery voltage (4.2V), the protection board will automatically power off and shut down, indicating that it will not continue to charge when fully charged, forms overcharge protection
  • Over-discharge Protection: When the battery is about to run out and the voltage is as low as 3.0V, the protection board will also be turned off and can no longer be discharged, forming an over-discharge protection effect
  • Short Circuit Protection: When an accidental short circuit occurs, the protection board will automatically shut down within a few milliseconds and will not be powered on again. Note that the cell is short-circuited (not through the protection board). The protection board will also fail due to continuous high current, or the components are heated and damaged
  • Note: The battery overcurrent protection is not a panacea, do not continue to charge and discharge the current and voltage with a large current beyond the range, otherwise the protection board will be damaged and invalid

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.

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.

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.

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

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.

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

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