Perfect replacement battery for the Miyoo Mini Plus
I'm a big fan of my Miyoo Mini Plus. I've been using it regularly for several years now. I take it with me whenever I travel anywhere (Train, Plane, etc). Recently, I noticed the battery was starting to swell. So with some research, I came across this. It works perfectly. An easy replacement for the original battery. The connector is small as the review say, but after a minute of fussing with it, it fit right in, without an issue. ... show more

MIYOO MINI PLUS replacement battery!
Good replacement battery for the Miyoo Mini Plus. Great price, and the packaging was appropriate. The connector is the correct size, but since it's so tiny it can be a bit tricky to insert if you have bigger fingers, so you may want to use tweezers or something. Battery is charged up on arrival so you can play your system right away, and the charge seems to last quite a bit longer than the Miyoo stock battery. While the battery is the correct size and voltage, I knocked one star off of my rating because it is EVER so slightly too bulky and I had to work for a bit to adjust the cables a certain way so that I could fully close the battery cover. I figured it out, so it's all good now. Overall satisfied with this product and would definitely buy it again in the future if needed. ... show more

Miyoo Mini Plus Battery
replacement battery for my miyoo mini plus. have had it for a few weeks now and works great. It took a bit of patience to get the small wires plugged into the correct places but was worth the it!!

Amazing battery, could be smaller in size.
Worked great. It could be 2mm shorter in length but other than that no complaints. Had to force it into place so I could close the case on my Miyoo mini.
