TX16S Battey 5000mAh 2S 7.4V XT30 JST-XH Plug TX16s Transmitter 1Pack

Works great and it’s a cheaper alternative to the other ones it fit right into my radiomaster boxer, battery quality and time is great size is small and not heavy

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

A good reliable battery for this radio.

I recently picked up the Radiomaster TX16S Battery (5000mAh 2S 7.4V) for my transmitter, and here’s my honest review: This battery is a solid upgrade if you want more usage time for your TX16S transmitter. It’s easy to install, and the plugs fit perfectly. However, it’s worth noting that charging this battery does take longer than expected. So, while you get extended usage, you’ll need to plan for longer charging times. But overall, if you want more power for your transmitter, this battery is a good choice.

Initially bought this for a Radiomaster GX12 but then bought a Jumper T15 because of the screen. It fits the Jumper T15 perfectly and it was easy to install. Battery tray was removed and the 2S balance lead plugs right in.

If your gear can use this 2 cell setup, do yourself a favor and get a few. Great quality!!!

I don't have any way to measure the capacity of this battery pack with a battery tester. But I recently bought this battery pack along with a RadioMaster transmitter. The battery seems to work fine. I'm thinking of testing the capacity of the battery pack by charging it to the maximum and then seeing how long the transmitter will run before the battery pack reaches 6.5 volts. I haven't done that yet because I haven't had that much time available that would allow me to check the battery often enough to keep it from over-discharging. If I find out more about this, I'll update this review with the results. At any rate, the battery pack seems to be working well. Update: The battery seems to be finally wearing out. It's got at least a couple hundred hours of use in a RadioMaster TX16S transmitter used for flight simulators (Phoenix, RealFlight And AeroFly). I'm getting about 3 1/2 hours use before the battery gets down to 6.8 volts. I used to get at least twice this amount of use before having to recharge the battery. I just ordered another new battery like this. You can ask yourself if 200-300 hours of use is good enough for this battery. I'm not really sure how long these batteries are supposed to last.
