RadioMaster 6200mah 2S Lipo Transmitter Battery For TX16S / TX15 / Boxer

Orginally thought RM 5KMAH Li-ION would be a better choice. Better for heat, less risk, charging, etc. No concerns with 2S Li-PO. No issues with heat, USB-C charging is great (researched this transmitter, balance charges), longer run times vs 5K Li-ION pack. TX16s uses a buck regulator reducing to a stable 5V. Either 5K Li-ION or this 6.2K Li-PO are great options. Having tested both, I sold my Li-ION and sticking with Li-PO. Transmitter power pull is predictable and low current. When not flying, I do pull my battery and run it down to safe storage voltage and park it in my LiPO firebox.

This is a great battery for my radio master 16s my 3.

Plenty of power for my TX15 and long lasting for many flights

Purchased this along with my TX15, no complaints at all.

Been Satisfied with it

So far so good

Good quality lipo. Must have for the rm boxer. Great service and fast shipping at helidirect.

RadioMaster 6200mah 2S Lipo Transmitter Battery For TX16S & Boxer

This really does stretch the battery life to the max for the radiomaster TX16s and Boxer radios. I have the TX12 and while it fits width, it doesn't fit the length as it goes into the expansion bay.
It is a bit of a tight fit on the TX16s as the foam on the battery cover really wants to push out the battery cover but so far it is holding.

Battery life for days and HeliDirect was great shipping time, cheapest price, and perfect service. Well done HeliDirect!

Perfect battery
