Long-Term Storage Voltage - 3.8V / Cell

With winter approaching I’m wondering if there is a better way to condition MA2 batteries for long-term storage.

I fly electric RC planes and helicopters and have several LiPo chargers that can cycle batteries and also set the voltage to 3.8V per cell for long term storage. See the photo below...

Right now, I quit flying the MA2 with about 10 minutes flight time left in the battery. It would be nice to connect the battery packs to a special charger to bring each individual cell to storage voltage.

Any ideas?

I don't worry too much about the mA2 batteries. They have been doing a nice job of discharging within the first few days of charging to a reasonable level for storage. I may tap them once a month just to ensure that they are not discharged to a very low level. If perhaps one doesn't discharge properly I would no longer trust the battery logic and not use it. I agree it would be nice to be able to do a closer inspection but I have not seen a reasonable way to do that.
