Very cool, with you basically all the way. Batteries is not an easy choice, really. What we really want to know most (what 'sag' and other compromises happen at our abnormal power levels) isn't generally available. Not the sort of stuff most makers want to brag about. 'However, our product only....' is not considered a positive way to start a sentence.
My only quibble is I've tried both the 1600 and 2000 mAh AW IMRs and the 1600s are actually a little lower internal resistance. They sag less and heat less than the 2000s (which are still much better than most). After trying both I bought another 1600 next time. I basically don't deep discharge them anyway, I don't miss the small drop in capacity as much as knowing it's giving maximum heat where I want it and minimum where I don't. A very fine point.
Small world. We went up to Dawson then turned North on the Dempster Highway, then under construction, with the Arctic Circle our goal. It wasn't done yet. We drove around the road block, found the (dry) camp, swapped the guy pealing spuds half a bottle of brandy for a suggestion. He directed us to a gravel pit to hide in for the night, the next morning we had to hoof it the last half dozen miles past the end of grade across the tundra to the river. Damn near killed me. Nasty stuff. Anyway, we swam the river, had a smoke and it was all South from there. At that moment we were further North than you could drive.
Please do think of Jim and I when you pass that way next. Makes a guy feel kinda small, doesn't it? How in the world did the poineers ever make it to the coast in wagons without roads? They walked of course, they only ride in the movies, who wants to eat that dust even if you could ride. People were made of different stuff. Just like Dempster (ever read his story?).
