MakerHawk 3.7V LiPo Battery 10000mAh 1163115 Rechargeable 1S Polymer Battery with Protection Board Insulated Rubber Tape, PH 2.54 Connector for Raspberry Pi Arduino ESP32 Development Board (1 Pack)

Very good and solid performing battery. I use this on my meshtastic TDeck with a custom care. The Tdeck last until nearly forever without a single charge. I'm very happy with the purchase and will be buying more to test on solar off grid nodes.

Works great, holds charge and last a long time. I use mine for a solar node I built. It's been in extream cold and heat, still working.

Powered a RAK meshtastic node for almost a month on battery alone. Just make sure your polarity is right. I had to switch mine to make it work

the first one came in with a completely detached power cable and a busted power management circuit. i returned it and order it again. The next one that came in is flawless.

Works great and love the bult in protectors for this module. Amazing capacity for how long battery last.

This was just a little too big for the case that I had. I kind of didn’t measure correctly and it was my fault but this battery is amazing for powering other small devices.

This listing lists this as a 10Ah 3C cell. This means it should be able to do 30A output for 20m at it's max discharge rate. However this battery is only capable of outputting about 2.5A, which is .25C based on the capacity and less than 1/10th what is listed. This is not fit for purpose, I did not receive what I ordered, this listing is fraudulent.

I have some ESP32 dev boards with integrated chargers, and this battery is exactly the monster I need to bump the run-time to the next level. I have been scrounging for mAh by learning how to use sleep mode and other techniques, but this MakerHawk battery provides more than enough capacity to keep my project (an intermittent environmental logger) running for weeks. The connector was exactly what my dev board needed, and the capacity seems legit. While I was a little wary of the potential danger of damage to such a high capacity lipo, I did 3d-print a protective shell to avoid physical damage. Current-wise, I haven't tested the max draw - I'm usually operating well under the < 100mA range, but this battery does have more than enough juice to drive a few servos (I was testing this w/ a boost module to drive multiple SG90s in a small Halloween mechatronic). The battery arrived in great condition, and well protected. I'm very happy with this battery, and will be trying additional MakerHawk batteries in the future. In passing, this battery does not provide an external temperature sense wire - it likely has a temperature sensor integrated into the internal BMS, but this is only a 2-wire charging cable.
