I’m not sure, I suspect this is way better. Just the 2S2P clunky battery carrier on the MF01 compromises it, as well as the size and weight, which is on the limit of usefulness.
I say that as an owner of an MF01, which has given good service, despite it’s quirks and some essential fixing-up required (fortunately mine was not glued up). This could be a worthy replacement
Just quickly slip 3 (or fewer, in an emergency) parallel cells into this, 350 or 650 long, All three cells perfectly balanced from the charger, and when removed.
No unwieldy heavy brass carrier to struggle with, three parts to drop, plus cells, only two hands, and multiple opportunities to get them in the wrong way around, in the dark, all those springs, studs, plastic rings and multiple contact points in the way, nevermind trying to prise out the cells from it without damaging the wrappers. I do not like battery carriers.
It even looks coat-pocketable with 18350 tube, balanced by some spares in the opposite pocket. The MF01 isn’t really, more a rucksack pocket device. Or a large brick when swinging from a wrist lanyard.
The fundamentals look good to me. Will be following early-adopter reports with interest particularly how well the new Anduril thermal control firmware performs in use.
