MakerHawk 3.7V 1200mAh LiPo Battery Rechargeable 1S 3C 603450 Lithium Polymer Battery with Dual Battery Protection Board, Micro JST2.0 Plug for IoT PDA Camera GPS Smart Development(1 Pack)

I use this on my PS3 game controller. Works great and last longer.

The pinout was reversed for what I needed (powering an Adafruit HUZZAH32). After fixing that I gave it a full charge to 4.2V using a MCP73831T-2ACI/OT set to 500 mA charge rate and then tested the capacity with a HiLetgo Battery Capacity Meter with a 7.5 ohm load resistor. This discharges at approximately 500 mA, similar to the charger's rate. The capacity to 3.3V measured 1106mAh and took 2.5 hours to complete. To 3.2V measured 1205mAh.Since the description claims over-discharge protection I then set the tester to discharge down to 3.0V. If the battery indeed has discharge protection it should prevent this since this voltage level will degrade the battery over time. From 3.2V to 3.0V the battery quickly dropped voltage and provided an additional 49mAh before the tester quit. Without load, the battery measured 3.3V, so it appears that the over-discharge circuit is working.Recharging to full 4.2V took 3 hours.Overall a solid option. I'ts nice that this battery is actually rated at 1S 3C. Many lower cost batteries don't providing #S and #C ratings.

Great for getting started with Meshtastic. Especially with a T3S3. Battery life isn’t amazing, but that’s more so the fault of the ESP-S3’s power consumption than the battery itself. It does work as you would expect but be prepared to desolder and resolder the connections if you're looking to get a battery for the T3 series. I'm sure there are adapters out there but I chose to re-do the connection. Soldering on new leads was a bit nerve-wracking. Was my first time soldering essentially directly to the battery's PCB. Patience is key.If you're planning to do any soldering or modifications I recommend wrapping the battery in heat resistant Kapton tape for added safety. On top of that, after the I would temp gun the battery for at least an hour to ensure nothing went wrong with the resoldering job. I cannot stress enough that working on batteries can be dangerous and if you're a novice to this you should proceed with caution and try to keep the battery drained/not fully charged when doing this procedure. Overall its a small battery that would work really well with the RAK series boards as they're far more power efficient.

I have this powering a RAKWireless Wisblock, and it lasts me days. Charges easily, ONE ADJUSTMENT NEEDED: this will not fit a Wisblock until you remove the terminal pins and reverse them. then it connects in and does great. I have this on a solar USB C charging system ,and it goes and goes and goes.

Needed a small battery for a small, portable LED assembly. This fits the need just fine, and seems to charge happily with a generic LiPo charge/overcurrent protection board. A male connector, or longer leads, or both would be appreciated, but not a killer for the design. It does seem to be at or near the rated capicity and has no issues outputting ~0.6A.

Great little flat battery pack that is a form factor used by a variety of devices and great for home-brew DIY projects too. Using it with a little environmental sensor I'm building and it fits and work good so far. I haven't done a full cycle discharge-charge-discharge to do a basic capacity check based on the stated specifications yet. So I'll try to do so if the performance of this seems out of line. Otherwise, the received battery pack is exactly as described and shown in the photos from the product information page. Would recommend.

This battery is perfect for an RAK Wireless Wisblock Starter Kit for Meshtastic. It has the right plug to snap right into the RAK19007 base board and the Wisblock can serve as solar charge controller for the battery. It's the perfect size to fit into Rak's 'Unify Enclosure Solar IP65 100x75x38mm' for a nice small portable solar powered node. This battery should be able to keep it going for a couple of days even without any light. If sunlight is consistent then it would be able to go indefinitely. I will update this review if I have any problems with the battery.

Fit perfectly inside my Rc controller. Now I don’t need any throwaway batteries
