WLTOYS K989 Battery Brackets
thingiverse
This is a modify battery holder for the WLTOYS K989 1/28 RC car which can accommodate larger lipo. I have been using this with a Gens Ace 520mAh 7.4V 30C for better runtime/power. Please note that I made the screw holes really small so you'll need to "bore" it out a bit as I wanted a tight fit...
