RDQ Series 3.8V 1S 660mAh 90C LiHV Whoop/Micro Battery - PH2.0

FAI F1 C

The batteries are used to power the electronic timers in our international class free flight model airplanes. The timer controls engine runs (less than 4 seconds) bunt, wing unfold, rudder setting, glide setting and DT. My only issue is I tried within minutes to change the number of batteries I needed but somehow you doubled my order and customer service did not respond to my request.

Awesome

Great batteries

Good battery. Pretty weak connector (not just rdq battery but many 1s)
