Worked great - as expected

They definitely are proud of this battery. A 2s can certainly be found quite a lot cheaper. That said, I didn't feel like dealing with possible fitment issues. This battery does fit (obviously) in my MT12 radio and lasts quite a long while. I don't know exactly how long, because I haven't wanted to risk losing power mid-drive. I've charged it, went on a RC outing with my brothers the next day (8ish hours of crawling), shelved it for a few weeks, then went out again (another 8hrs or so) and it was still at 7.7v at the end of that day. This single battery can certainly last through a full weekend of RC activities, at least while in the Radiomaster MT12 4in1 that I'm using. Also, it's convenient being able to just plug the radio into my phone charger, rather than having to hook up yet ANOTHER battery to my charger.

I charge my tx16s once a month or so now instead of every time I go flying. I highly recommend this as a qol upgrade for your tx16s if you aren't already using larger 21700s
