This (and other 606090 cells) are the right size for expanding your Vita 1000's battery life, assuming you don't have a 3G model and don't mind trimming out some plastic from the rear shell. And tearing open the stock battery to get the BMS and connector, that part's pretty sketchy ngl

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.

I purchased the Qimoo 606090 3.7V Lipo Battery to replace the battery in my Keychron K8 Pro, based on the listing’s claim that it uses a JST PH2.0mm connector. Unfortunately, the connector didn’t fit my keyboard, which was really disappointing given that compatibility was the main reason for choosing this model. While the battery itself appears well-built, it’s not useful if the connection doesn’t match. Make sure to double-check connector sizing before ordering. I ended up soldering the old battery's connector to this. Pros: - Solid-looking build quality - Good capacity at 4000mAh Cons: - Connector didn’t fit Keychron K8 Pro despite listed specs - Misleading compatibility—returned due to incorrect fit

Yo! This battery was perfect to extend the run time of my spy smoke detector cameras! The factory battery only lasted like 2 hours. Now these cameras run 10 to 14 hours a charge. LOVE IT! It was the perfect size

Esta bateria me quedo perfecta para mi teclado mecanico Keycron K10. Si es bien complicado el cambio pues hay que desarmarlo todo completo pero se puede. Tener cuidado con la plaridad pues venian invertidos y tuve que cambiar el + y - al revez en el conector de la bateria nueva.
