  • Good battery.
Works well with my LoRa node. I've been through a couple cycles with it and it's working very well. 5200 mAh lasts about 2 weeks with the RAK 4631 module. It was a direct fit connector, but I did have to swap the wires in the connector to get polarity set right. I'm really happy with the quality of the battery thus far. ... show more

  • Capacity seems good so far
So far, so good. Replaced lion battery in temu lamp that had failed. Perfect fit but needed to cut off connector for expedient solution.

  • Big Capacity, Solid Option for DIY Projects
This 5200mAh battery is holding up well so far. I’m using it for a low-power outdoor project and the extended runtime has been great. The JST-PH 2.0 connector fit my setup, but definitely check the wire orientation—mine needed a quick swap. Nice to see it came with guidance on that. For the price, it’s a solid pick if you need a long-lasting 3.7V power source. ... show more

  • Fixed dead fan
The battery in one of my fans failed and this was a perfect replacement. Holds charge well and last longer than the original battery in the fan
