SoloGood 7.4V 2S 6200mAh Large Capacity Rechargeable Lipo Battery with XT30 JST-XH Connector Compatible Boxer TX16S Transmitter RC Car Drone Controller

These lipos were specially designed for the TX16S & Boxer Radio and they fit perfectly and last a very long time, but they are heavy... These are the only batteries I use in my two radio's TX16S Max & Boxer Crush... Great investment...

Lasts forever in my boxer

Fit the radio as expected and works very well. Powers the radio transmitter for days before recharge is needed.

Works great, my son uses it for his remote control and says it lasts a long time.

Love it, fits radiomaster boxer perfectly, allowing me to use it for at least a week at a time

Very long battery life for radio master boxer

Great battery!

Have only fully charged it once.. still running my RM Boxer w/ a little less than ¾ of juice from first charge. It's nice not having to replace battery's often!. That goes for anything that takes batteries really. Lol I actually haven't been able to fly my 5inch just yet.. so really just been using the Boxer for Velocidrone Sim.. seems to not depleit the cells like you think it would. Fits nicely in battery compartment of Boxer, with long main leads to be able to run it out of compartment to power up an external module if you decide to do so. And as for mah, 6200mah
