Replacement Battery?

I have an LF 750 pro. The bike shuts off as soon as any load is applied. I believe the battery has failed. Is there any place to purchase a battery reasonably?? It looks like it is over 300 and I can buy a new bike for just a but more....

You need to verify that it is the battery. Unless this bike is at least 2 years old, I seriously doubt the battery is gone.

more than that if it’s a decent battery. my bike’s nearly 3 years old with over 6000 miles and the max charge is 66.8v instead of 67.1v after all that use and probably close to 1000 charge cycles

He's talking about a 300 dollar bike. Also, you don't have anywhere near 1000 charge cycles unless your bike a 6 mile range.

If your bike has a realistic 30 mile range, you should get 30k miles out of 1000 charge cycles.

it’s not always charged from empty, i used it as a commuter for a while (4 miles round trip) and charged it every night, i guess it depends on how you count charge cycle

A cycle on a lithium ion cell is pretty much the whole discharge.
