Hi and welcome
There is no other kind of batter for the RP to my knowledge. Nor does Canon have a battery grip, however there is a 3rd psrty on available that taked 2. You would use it at your own risk. Google RP grip to find it.
You could try the R7 that uses Canon's most piwerful battery.
cheers, TREVOR
