Being mostly a warm weather shooter, I've not much experience managing batteries in cold weather any helpful ideas or insight would be appreciated.
I'll be working from a base camp, there is no power at the base camp.
I'll be shooting for ten days with Pentax 645D charged battery is rated at 400-600 frames
I plan on bringing six fully charged batteries.
I plan on keeping these batteries warm inside my gear clothes/sleeping bag, and rotating them out as the working battery gets cold.
Most likely I'll hike out, hopefully only once to stay in town and recharge my batteries, and my batteries!
the expected mean temp is 0C
Again Any thoughts on cold weather/ batteries etc would be appreciated.
