MakerHawk 3.7V 3000mAh LiPo Battery Rechargeable 1S Lithium Polymer Battery with Protection Board Insulated Rubber Tape, Micro JST 1.25 Plug for Arduino NodeMCU ESP32 Development Board (4 Pack)

These batteries are great. Came partially charged to get your project running so you can then fully charge them up. The size, obviously, is larger than the 1100 and 2000 size batteries so you know in case you’re choosing to put them into the 3D pre-printed Meshtastic style protective cases. Regardless they fit perfect with the option of being mounted externally. These batteries are very well constructed and securely wrapped with solid connection wires and the 1.25 plug tip. Price is super competitive for such an easy item to use.

Awesome batteries for makers. I have them in several of my Meshtastic devices, and the battery life is great. They are all standard size and fit my 3d printed cases for 3000mAh batteries great. Buy this for a great fit and function in all your maker devices, as they are reasonably priced and work well.

The battery life on my mesh T echo was very good with its original battery but I upgraded the 850 battery to a 3000 and now it lasts about a week without needing to be charged. The functionality quality and fit was perfect for upgrading my unit. I’m sure you can use this battery for many many different uses.

works as promised

Exactly what I needed. Fast shipping, perfect product.

Once my original Miyoo Mini Plus battery could no longer charge up. I needed to find an alternative. This fits perfectly and works well as a good replacement.

I got these for an Arduino project I am working on and they worked great. They are a little thicker then I expected. The charge and maintain charge just fine.

I use this on my PS4 game controller. Works great and last longer.
