About This Product

For all you DIY electronics folks and gadget repair enthusiasts, this 300mAh 3.7V LiPo battery is super handy to have around. The 602030 size (that's 6mm thick, 20mm wide, 30mm long) makes it compact enough for all sorts of small wireless devices. It comes with a JST PH2.0mm connector and two wires, which is pretty standard for lots of modern gadgets. The battery includes a protection board too - that means it's got safeguards against overcharging, over-discharging, short circuits, and overcurrent situations, which is great for peace of mind. You can use this for so many things - wireless earbuds charging cases, reading pens, fingerprint door locks, small robots, model cars, speakers, and tons of other portable electronics. If the wire polarity doesn't match your device, you can actually swap the red and black wires pretty easily (just be careful not to cause a short circuit while you're doing it). The 3.7V nominal voltage works with most small digital devices, and the 300mAh capacity gives you decent run time for compact applications. It's rechargeable of course, so you're not constantly buying disposable batteries. They even offer a 3-year replacement warranty, which is pretty impressive for a battery. Definitely one of those components that's good to keep in your repair kit for when you need to replace worn-out batteries in various gadgets. Much cheaper than buying replacement parts from the original manufacturer too!
