802030 3.7V Lipo Battery 400mAh 802030 Rechargeable Lithium Polymer Battery Pack with JST PH2.0mm Connector for Electronic Device

I made the dumb move of replacing the battery on my brand-new solar powered radio because the factory battery just wouldn't hold a charge. Turns out the factory battery wasn't at fault; it's the radio itself that's defective. It apparently continuously discharges the battery, whether you're using it or not. So... this battery was the perfect replacement and works great. Since the radio is junk, I now have a spare battery. I don't know what to do with it, but I'm sure I'll think of something. :-)

Worked perfect for my daughter's car

Battery works great for my heltec v3 running Meshtastic. Great value for money.

Product works fine, but be warned that the polarity on the connection was backwards, and nearly nuked my electronics. Take time to double check what you get, and use tiny screwdriver/pin to remove the small connections and switch them up if needed.

Bought this for a Lilygo t-deck. It works and requires a thicker back on the case, as well as a swapped power connector. Not a drop in replacement but it will work.

Our Rv tablet kept dying and wouldn’t come back on. After doing some research we found out this battery would work for our needs. It is performing as expected and our RVs systems are working perfectly. It fit in the case and was the size the description stated. It was easy to install after we got the tablet open. I’d buy again at this price! Good value for sure!

Those who are buying this specific battery with the connector to replace bad Keychron K4 batteries, this battery works with a small modification. The pinout on the connector is reversed. You don't need to cut the wires and modify it. Take a sewing needle and there should be a small tab on the plastic connector holding each of the black and red wire. Lift one of the tabs carefully and it should allow you to pull the wire along with the soldered pinout. Do the same for the opposite wire. Reinsert in opposite slots. Plug into keyboard and should work like new. Taking the pin outs from the plastic connector requires a bit of patience and finesse if you are doing this by hand. The tab that you pull up is really small and hard to see if you can lift it up, but if you have a sewing needle, you can definitely lift it up. it might be easier to place the plastic connector in a mounted vice while you have both hands to lift up the tab and pull the wire.

The title says it all. Good price and works great.The use I had for my old 303450 Lido battery lasted 20+ hours.On the first charge this new one lasted 16 hours. But I have heard that within the next charge or two the run time may increase.Overall a good deal!
