New Lithium -ion bike battery.

[melvyn]

I read somewhere that I should run my new battery flat twice to begin with, is that correct?

Not usually required with modern batteries, but there's no harm in, er, 'cycling' the battery now and again.

What you absolutely don't want to do is run it dead flat.

The battery management system on your bike should stop you doing that - it will cut the motor before you can do any damage.
