1pcs 3.7V 10000mAh Lithium Polymer Rechargeable Battery 1S LiPo Battery with Protective Board, Insulation Coating and PH2.0 Plug for Raspberry Pi Battery Pack UPS and Other

Good value for what you get. I've been running this battery in my solar-powered Meshtastic node for nearly a year now, and have no regrets. The design and size of it fit inside the enclosure I purchased without issue, and functions just as I'd expect. Easy to hookup to normal screw-terminals common on Meshtastic radios. Would buy again.

So far so good on the RAKwireless Meshtastic node I am building for my roof. Takes a long time to charge but I think the charging circuit on these boards is not very powerful. Will need to do some run time testing before adding the solar enclosure. The goal with the big battery is 24/7 operation year around so we will see how it does. NOTE: the wires need to be pulled out of the connector first and swapped before you plug it into the RAK base board. Always check the polarity! EDIT: Ran the RAK Wireless node on my desk for over a month off this battery without plugging it in. This will most defiantly keep my node up during the winter here in Central CA.

This high-capacity LiPo battery has proven incredibly reliable for my Raspberry Pi UPS setup. The 10000mAh capacity provides excellent runtime, easily keeping my Pi running for extended periods during power outages. The integrated protective board gives peace of mind against overcharging and short circuits, while the insulation coating adds an extra layer of safety. Installation was straightforward thanks to the PH2.0A plug, which connected directly to my UPS board without any modifications needed. The build quality feels solid, and I appreciate that the battery came partially charged, allowing for immediate testing. After several months of use, I haven't noticed any significant capacity degradation. One minor consideration is the physical size - it's larger than some lower capacity options, so make sure you have adequate space in your project enclosure. The connector is well-secured, though I did add a small dab of hot glue for extra stability in my portable setup. The battery maintains a steady voltage output throughout its discharge cycle, which is crucial for sensitive electronics. While it's not the cheapest option available, the combination of reliable performance, built-in protection, and high capacity makes it worth the investment for anyone serious about their Pi projects or other electronic builds requiring stable portable power.​​​​​​​​​​​​​​​​

I bought this battery to replace the dying 4000mah battery in my Keychron keyboard. It was a tight fit and required some modifications to the rubber gasket on the keyboard, but after getting it all wired up, it’s been fantastic! My old battery was lasting me around 2 weeks between charges. I’m currently at 2 months and 60% remaining. The math doesn’t exactly add up, but the proof that this is working a ton better is right in front of me! One thing to note if you’re going to use it for the same thing I did was that the connector that comes on this battery was larger than what my keyboard used, so it required a little bit of extra work to attach the old battery connector to the new battery

Using battery on a Meshtastic solar node. Small charger controller and solar panel. So far it’s working perfectly. Just a 5V solar panel and tiny charger controller all working perfectly. Definitely recommend battery for your projects. Be sure to use proper charger.
