What is everyone using to discharge there batteries to the proper long term storage voltage?
Also are you using this same thing to bring the battery to the deep cycle voltage after 20 flights like DJI recommends?

Are these any good to use for this ?:

I only charge my batteries when I'm going to use them (or if they get too low in storage). If I charge them and don't use them (doesn't happen often), I let them auto discharge down to the storage level.

DJI batteries do not need to be deep cycled. You can safely ignore any recommendations to do so.

Hi, Thanks for your inquiry. May I know what specific drone are you using so that we could help you? Thank you for the support.

DJI batteries are smart batteries ie all the charge and discharge control is built in androne as said by msinger I also allow them to discharge themselves to the storage level and have done for almost two years.
