Outrageous! 117th battery, anyway! I do not put informed before buying my Canon G7x (device which is fine but has a much too low autonomy). I do not find it normal to have to pay 1/5 the price of a camera in a second battery.
I would know for the next time ... I hesitate even to go at Sony (with their RX100M3) just for that ... official batteries found in 24.00! (Chinese to 8euros ...)
In short, I am very disappointed to see Canon sell a single battery to 117 !!
