KBT 3.7V 1600mAh Li-Polymer Battery: 103241 Rechargeable Li-ion Batteries Replacement with 2.54 JST Connector for Headlamp, Ar duino NodeMCU ESP32 Development Board Raspberry Pi UPS Board

Works great with the 8bitdo M30 wireless controller. It’s an upgrade on hours too. You do have hm cut some plastic out from the back of the controller .

Word as expected.

I love these batteries and use them in all my DIY projects. They are a lot cheaper getting through Amazon than from the manufacturer or China. The only issue I have with these batteries is the plus and minus are switched on the plug end. No matter as it's easy to swap the around but you need to be careful not to short the together. Great shelf life as well.

My dash camera wouldn't hold charge any more, so instead of buying a new one, I decided to just replace the battery. Found these brand and is working great! And I have the second one just in case.

Purchased for a helicopter I fly in the house to amuse the animals. Have lasted well.

Sold as 9500 mAh - Measured at 8370 mAh capacity (at 70 Farenheit into 4 Ohms). The built-in protection circuit cuts out at 3.25V. Charging starts out less than 2A and drops rapidly below 1.5A. This seems very slow. Weighs 170g.

Worked fine, I was able to fix my dead coffee scale

I bought multiple sizes of these, and while the bigger sized met the specs as far as I can tell, the smaller ones do not. I was buying these because of the 3C discharge rate, however the 602035PL 380mAh battery maxed around 1.5C (585mA) instead. The big 5050 size over delivered a bit, and the 952259PL 1400mAh delivered right at 3C (4200mAh). Since my project requires a discharge of at least 1.8C (700mAh) the smaller batteries I really wanted to be able to use will not work (I need load not duration).

buen producto lo recomiendo
