    • Useful battery, but double-check the polarity!
Size: 112945 (1400mAh)
As noted in the product title, beware of the polarity. For some reason, there are two common wiring conventions. Since I've been using a lot of Adafruit boards lately, I needed it wired for "center negative." I tested it right after it arrived and quickly reversed the polarity. No soldering needed — just a male and female JST cable and some solderless connectors like Wagos. Moral of the story: always check polarity before plugging in a LiPo! Once rewired, it charged and worked perfectly with my dev boards. ... show more

    • Sedici Bluetooth battery replacement
Size: 602248 (620mAh)
I replaced the battery on my Sedici Bluetooth helmet. The battery is the same size, but the connector did not work. I had to splice the wires in with butt connectors. So happy to have a bluetooth that last more than 20 minutes.

    • Worked well for a BEM mini speaker.
Size: 542730 (340mAh)
I bought this to replace the battery in a BEM mini speaker. I did have to remove the connector to solder directly to the board inside but it's been working like new again. I ran the speaker for several hours after a full charge and it still had pretty of juice left. I would buy this again

    • Solid little battery pack for small devices
Size: 803048 (1200mAh)
This battery works great for powering speakers and other small wireless gadgets that take a 3.7 V Lipo with a JST connector. It fits neatly into compact builds and holds a reliable 1200 mAh charge through several cycles. The JST pigtail connector felt snug and didn’t wiggle loose even when I was moving things around. Setup was easy as long as you double check the polarity before plugging anything in — the warning in the listing is fair. My only small issue is that the battery doesn’t come with any mounting tape or foam pads, so you’ll need to improvise some cushioning in your enclosure if you want it snug. Other than that it’s performed consistently without swelling or dropouts. Great value if you need a lightweight LiPo pack for DIY projects. I’d give it four stars because of the lack of built‑in mounting aid but otherwise very solid. ... show more

    • Horrible
Size: 602248 (620mAh)
Battery was stone dead on arrival. Had to take the kapton tape off and directly charge with a precision power supply cause the 0.2v battery state wouldn't get recognized by any normal battery charger. Yeah it's pretty pucker inducing to have to charge a lipo pack that way. Longevity also seriously suspect for it having been in that state ... show more

    • So far, so good…
Size: 803048 (1200mAh)
I purchased this to replace and upgrade the battery in a shower speaker. It works great right now, but I will update this in exactly one year, and every year after that until it dies, so everyone can see how long they last.
