I was going to buy one of Rons battery setups but since I already had the battery box for making my own I did that-Go to the classifieds and Ron has a bunch of his setups there-You can also try just buying a new battery and see if that fixes your problem 😐

Thanks

Many replacement battery options if you search on Amazon for the Sony battery.

hi. with my gpx i have two batteries with the reference sony NP-F980L, i fully charge them, but when i put at the gpx after a few minutes, it start's beep, and turn's off. the sony battery say it has xx battery, but the gpx say it has yy battery, so i supose the batteries are finished (with a original gpx battery it doesn't happens... it last for a few hours). i attached some photos, and the connections that the last person had made to it. 

looking at the Lightweight GPX Battery kits at the internet, i see that who made them use NP-F970/F960 or NP-960/970, i see they put a wire inside the battery... but at this battery i have it's only connected at the top of the battery... does anyone have photos or a youtube video how they are made? 

or someone have lightweight alternatives of batteries? thanks
