Hey Friends!!!!!
After a few years of chipping away at this project I have decided to release it.
DIY Onboard battery mount for your SR3

Comes with optional 2 pin lemo ports (up to 3)
Can have a fully functioning hinged battery converter for around $700 total
Instructions and parts list are found in the google drive in the description link
Instructions are still fairly basic but will update with better pictures in the future

IT'S DIY SO NO WARRANTY OR SUPPORT IF YOU BLOW SOMETHING UP.
Will try my best to answer any questions
