Ancheer 250 Electric Folding Bike 36v/8Ah Needs New Battery Or Battery Jump. Also needs New Screws For Batjtery Connecting Plate

This is a barely used ancheer 250 foldable e-bike. However the Battery does not seem to provide enough power to control the motor, but the bike will still turn on. It currently works as just a regular foldable bike, but with a new battery or jump, it should travel up to 17mph on full throttle. It has pedal assist mode as well and it has 20 in wheels I believe. I really wanted to fix it myself, however I still have way too many other projects that need to be done and I was thinking of getting a smaller e-bike anyways. But this thing is very fast on all terrains and can travel about 15-25 miles on a full charge. It's load capacity is 265 lbs and the bike its self weighs about 40lbs. I just want it to be known that although it needs a bit of work on it, it is still a sweet bike that should definitely be worth more than I'm selling it for since it costs about 600 brand new and I'm just hoping to get about 250 for it. Should be an easy fix and I will also include the extra motor controller just fir back up. I might see if I can find the missing screws, but I'm hoping the low price I set will make up fir that.
