So I have few batteries. TB47's and TB48's all batts are complete discharged every 10 flights, only charged after about hour of cool down, no extreme hard flying, outside temps are in 70-80F, always land drone at about 20-30% of life left except every 10th flight when I drain them down to ZERO. all I can say batt's are well taken care of. I came from 3D helicopters (T-Rex 500 and T-Rex 600 electric) of last 7 years and I know all there is about lipo's, charging and taking care of batteries. all batteries about same story with life % of the batt's. after 12 charges showing 96% life 20-25 charges showing 95% life after 30 charges 93% life. you kidding me? if they keep up like that I figure month from now they'll be 50% life, LOL??? Anyone with resolution on this?
