That's basically good advice for any smaller saw - not just battery jobbies. Keep the chain sharp however you prefer to sharpen them haha and the rakers at spec and they'll cut like little troopers. Also a good comment about the chain tension on the smaller bars - they definitely do not like being as tight as the bigger 3/8 gear.
The biggest disadvantage in my guesstimate from petrol to the battery saws is the little battery jobbies are heavier and the balance is just different. But then if you've used an electric saw the same comment applies - balance is just different to the petrol equivalent. With a good, freshly charged battery the battery saws are bloody good - but if you grab it after a few months and the battery isn't holding it's charge yeesh what a pain in the arse. Again though with petrol you have to be careful with storage life and having to fart about mixing fuel - no free lunches.
