Before you replace your batteries remember cold temperatures affect SLA battery capacity. My batteries are doing a similar thing and they are less then a year old. Most likely your battery pack is fine. I suggest wait until a warm day arrives and then ride with a charged pack. If they still have a reduced range then replace them. But if they work normally again then do not replace them because it is the lower temperatures that is affecting them not damage or deterioration.

"What he said"...
Are you parked outdoors nights? Daze? No loose electrical connections (no connects etc feel hot after a ride)?

I've already verified this behaviour, as even on the warmer days these past several weeks, the speed and range have been lower than usual. I park/charge my bike indoors both at work and at home, so the battery pack is definitely being kept warm at those times.

Remember that a few months ago I had the issue with my charger possibly overcharging the battery pack, similar to what happened to yours Ken; so I'm thinking that the after-effects from this may be starting to show now.

Well now that you told me the details it does sound like it is time to replace your batteries.

With this talk about gearbox oil... thought you might find this thread amusing:

So to follow up on things, Monday evening I brought the Condor down to Bill's and charged it up for a bit. He's a good guy and I enjoy hanging around the shop and helping out if I can. So we took apart the battery pack and tested the individual cells, and after finding them all to be within normal parameters, we were a bit stumped as to what could be causing my problems. We were thinking motor, controller, electrical system... any number of possibilities.

Bounced a few ideas off each other, and ultimately, believe it or not, wound up loosening my rear brakes again. A LOT. It took about 10 full "turns" of the rear brake adjustment to get it to where it was supposed to be! They were so tight that, even after loosening it a few weeks back, the bike was resisting against the motor as well as going downhill, which was what really had me wondering before. I know the hub-motors do this sort of by nature, but not to the extent I'd noticed as of late. I also put a little bit more air into the rear wheel, since it seemed to have lost some pressure.

For the time being at least, my battery pack seems to be back where it should be, and the ride is faster again. I feel like a dolt, but it seems as if someone may have been messing with my bike when I'm not watching: this isn't the first time I've noticed something was "adjusted" while I was away from it.

Man, what a relief... now I just have to keep a closer eye on things!
