What kind of battery should I get for my SX Mini? Should I get a charger for it or should I charge through the device?
^^This^^YIHI says you can charge in the device but recommends not doing it. I suggest Samsung 25R or LG HG2 batteries. They work the best for me. I'd also suggest getting them from Liionwholesale.com and a charger. I use the Nitecore I2 It's cheap and it works.
Do you have the M or the ML? If it's the M class the latest up date will give you all the features of the newer ML class, just get the English version not the Chinese.
