I use lipos, and lipo capable ubec's in all my nitro airplanes. 8-10 flights from a 3s 1050mah 5c battery, and STILL have 10.5 volts in the battery, recharge in 15-20 minutes, putting back in only +- 600mah. I know how my batteries will perform before I use them in the air, and am finding no need for access to an electronics lab setup to "monitor" them. My accucell 6 does that job for me...<div> </div>
