3.7V 5200mah Rechargeable Battery Pack Lithium Ion Batteries with JST-2P Connector for RC Truck, RC Boat, RC Stunt Car

First things first.. MAKE SURE YOU CHECK AND DOUBLE CHECK THE CONNECTION TAB!. There are few out there that look similar, make sure you're positive you are getting the right connection. Now to the review. This battery pack is perfect for my needs. I have a foam sprayer that the battery crapped out after one change, somehow one of the leads inside the pack completely rusted out. So I ordered this pack and it fit perfectly. The battery capacity is nearly double what the original had. Installing took like two seconds. Connectivity is a breeze, the instant I connected it, the power button lit up, showing it worked. The price on this is great. Plus it saves me from having to buy a new sprayer, and saved mine from ending up in a landfill. The sprayer is charging as I type this, so I can say with confidence that the battery works and charges. I'll update if any issues arise.

Hold on to your hats, folks, because I've got a battery review that's going to blow your socks off! So there I was, sitting in the dark, staring at my glo ball like a lost puppy, wondering what could have possibly gone wrong. And then it hit me like a bolt of lightning - it must be the battery! And let me tell you, I was right on the money! Now, I may not be an electronics expert, but I do know my way around a screwdriver. And with a little elbow grease and a lot of determination, I was able to pry up that IR sensor and get to work on that LED mounting board. And boy, was it worth it! This battery is a real game-changer, folks. My old battery could barely hold 2000mAh, but this bad boy? It holds a whopping 2600mAh! It's like upgrading from a tricycle to a Ferrari. And let me tell you, the installation process was smoother than a baby's bottom. All I had to do was unscrew a few screws and unsnap a battery cable link, and I was good to go! I've been using this battery for a little while now, and let me tell you, it's a real lifesaver. My glo ball is shining brighter than ever before, and I've got this battery to thank for it. And at such an affordable price, it's a no-brainer. So if you're looking for a battery that'll last you for years to come, look no further. This baby is the real deal. Just make sure to double-check those connections and power/voltage specs before you start installing, or you might end up with a firework show instead of a glo ball. But other than that, I highly recommend this product for all your glo ball battery needs!

I used this battery to replace the battery in my Snapon LED inspection light it has a different connector is not the correct style, but I was able to solder the wires and it’s been going strong ever since definitely worth the price compared to the $125 fee that Snapon wanted for the battery replacement

The battery works great for my flag light.

I build portable arcade machines using a Raspberry Pi 5 and wanted to make it battery powered. I researched how I could do this which led me to purchase a Geekworm x1203 UPS Shield, and this battery pack. This battery is compatible with devices that use XH2.54 connectors which is what the Geekworm uses, and I'm able to get surprisingly good battery life on my builds with this 5200mAh battery even with the system potentially drawing up to 5A (I get approximately 2 hours per charge). Since the battery is quite small (2x18650 batteries), I may make a build using 2 of these batteries in the future since the Geekworm board accepts two battery inputs. In all my research this seems to be the best value battery pack for my build based on price and capacity.

POOR QUALITY BATTERY. BATTERY DIES WITHIN 30 MINS OF USAGE EVEN IF FULLY CHARGED. DIDN'T EVEN LAST 1 WEEK. TERRIBLE PRODUCT

Worked flawlessly with my drone controller

I purchased these for a pair of 8-year old Barebones Forest Lanterns that were starting to not hold a charge. I tried to purchase replacements from the manufacturer but the newer version of the lantern uses a different battery that is not compatible with the old model. This one worked great - the only issue was the reversed polarity on the connector. Fortunately the wires are easy to switch in the connector, and after that it was plug and play.
