I found manual unpowered bow- or chain-saws (simple chain and handles, no motor etc) much better for just this purpose. They are easy to carry around and are faster to start and stop using - exactly what I need when something fell unexpectedly, not a clear-cut type of jobs.

"Ridgid" is a brand!?

Oof ouch owie my orthography

Smaller chainsaws can be more dangerous than bigger ones, watch out for kickbacks and learn how to use a chainsaw properly so you don't mangle yourself up. Do not get fooled by the lack of noise from an electric chainsaw, they can still fuck you up

Having said that, yes, you'll be able to handle them more easily. I don't know enough about that brand to comment on it, but as you said, you already have a bunch of batteries available for it. Watch your footing and have an understanding of possible tension and compression forces on those limbs

But do you really need it? Are debris a common occurrence on your hike? I won't deny chainsaws can be useful to have around, but you mentioned it would only be used on the trail and you already have a sawsaw

Btw, which blade are you using on your sawsaw? You might want to get a pruning blade if you are using a standard carpentry blade, as they can be way faster too

If you're using a chainsaw make sure you're wearing chainsaw chaps, a face shield, gloves etc. The chaps especially can save your legs and your life when the saw kicks back (and it will at some point) - especially if you're out in the sticks and alone.
