IF you use a decent 1 C battery you can charge and discharge the lithium battery at the C rating.

For example a 100 amp lithium battery with a 1 C rating can charge at 100 amps, it will be fully charged in 1 hour.

A 100 amp 0.5C lithium battery can generally charge/discharge at 50 amps, it will be fully charged give or take 2 hours.

It is not advisable because it will shorten the life cycles.
