A Great Battery for the SAM Speed 4300 event

"The 850 RDQ 2S 8 50 mah lipos are my battery of choice for the Society of Antique Modelers Speed 4 00 RC event. They are easy to fit in the old time model designs; pack a good punch for the climb, and have more than enough capacity for the climb and glide parts of the flight."

6 charges. So far so good

More mah more flight

"These little guys are perfect for my cinebee75hd and 110 damfast frame. 850mah gives me up to 2 more minutes of flight than the 650mah. Best of all they have RDQ wrote on them."

Perfect Twig and 2s Whoop battery

"Great battery for both my whoop and my twig. 35g battery great flight time. Still using some from 3yrs ago."

Was hoping these would be

"Was hoping these would be an upgrade from the RDQ 720s but I'm disappointed. Worse performance in both handling and longevity. Maybe I got a bad batch, the internal resistance on delivery was ~25mΩ per cell or worse. With light flying it can barely make it to the 5 minute mark in my Pavo Pico w/ naked O3, something the 720s can do pretty easily."

They work as advertised so

"They work as advertised so far. Got the full range out of them, and I'm seeing about 0.5v of sag at 20A draw. Pretty happy with the way they perform."

— Jayson R. (5/5)

I like them

"The best thing I ever did was solder on a XT30 connection . with these 850s my tiny hawk gets 11 minutes of flight time."
