Here is a great battery mod by Enthusiast Guy a great video and he really goes into good detail as to what you need to do. Mario thank you from the community keep your videos rolling in :)
I purchased the battery off AliExpress. It was advertised at 4000 mAh, but measurements showed it's actually a bit over 2000 mAh. So, I wouldn't recommend buying that brand with the white and blue. Instead, look for batteries with silver cover and a code on them that describes the battery dimensions and capacity. For example, you would look for a battery that's 6mm thick, 8 cm long and 5cm wide to fit, so you would search for 605080 battery. Personally I bought batteries from this guy in the link below and they are ok. So I recommend buying from him:
