RE: What's the latest in batteries?
QC, I, like Verne have charged my batteries with the Cellpro 10s charger for the last 3 years. Currently my IR readings for the Sky lipo 4400mah 20c 5s packs are between 1.7-2.6 after 24 flights. After 49 flights on the Nano 4000mah 25-50c 5s batteries the IR readings are between 2.8-3.7. BTW, the Sky lipo's and the Nano packs are still strong after 6 1/2 to 7 minutes and their performance is very similiar including the amps Hope this helps, Everette
