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.

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.

Battery works as expected and performs great

this battery discharges at rest way too high. Poor quality, unusable. low quality, poor function

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.

This battery offers 10Ah at 3.7v, which is a lot when using it for a microcontroller and LoRA. It is easy to use, with its pre-existing connector.Being Li-Po and not Li-Ion makes it able to withstand slightly lower temperatures without any issues, which is perfect for a upcoming project of mine to monitor my refrigerator's internal temps. I was concerned about how I was going to power the project, since all I had was a 10Ah Li-Ion battery, but with this Li-Po battery, since the fridge won't be dropping under 0C, it should be fine.Overall this is a nice battery, and it should not give you any trouble so long as you treat it right.
