  • Highly Recommended: Perfect Battery Replacement for Monster Clarity Bluetooth Speakers
Style: 803040 1000mAh
This battery replacement for my Monster ClarityHD Bluetooth speakers was a perfect fit and incredibly easy to install. The process went smoothly, and the new battery is slightly smaller and lighter than the original—making it even easier to secure inside the speaker compartment. No issues at all, and the speakers work like new! ... show more

  • It’s a battery
Style: 1260110 10000mAh
This high-capacity LiPo battery offers reliable performance for electronic projects. The 10000mAh capacity provides substantial runtime, while the integrated protection circuitry safeguards against overcharging, over-discharging, and short circuits. The JST PH2.0mm connector is well-secured and compatible with many common development boards and electronic devices. Build quality is solid - the cell is properly encased with good insulation, and the wire gauge is appropriate for the current rating. The voltage stability remains consistent throughout the discharge cycle, which is crucial for sensitive electronics. The battery arrives partially charged, allowing for immediate testing while still maintaining safe storage levels. The form factor is well-suited for many project enclosures, though you'll want to verify dimensional requirements as it's substantially sized. The connector pins are properly aligned and make positive contact, though adding a small dab of hot glue for strain relief is recommended for portable applications. Self-discharge rate is minimal during storage. One consideration is the charging time - it requires patience with standard charging rates to maintain cell longevity. While not the most compact 10000mAh option, the protection circuitry and build quality justify the size. For makers and electronics enthusiasts needing reliable portable power, this battery provides a good balance of capacity, safety features, and value. ... show more

  • Fits Acaia Lunar with connector swap. So far works great.
Style: 503759 1200mAh
Perfect fit to replace the battery in an Acaia coffee scale. I did have to swap the connector. Hopefully this one lasts longer, but the price was good.

  • Good Replacement Battery for an Anykit Borescope
Style: 755068 3000mAh
Purchased this as a replacement battery for my Anykit 1080P borescope. It’s slightly smaller than the original but has a higher capacity (3000 mAh vs. the stock 2500 mAh), and so far it’s working great — noticeably longer runtime and holding a charge well. Swapping the original battery in the Anykit scope was a bit of a hassle, but the Qimoo battery connector had the correct polarity for my unit, so installation went smoothly once I was able to get the original battery unglued. ... show more

  • Connector Didn’t Fit My Keychron K8 Pro—Disappointing Compatibility
Style: 606090 4000mAh
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 ... show more
