Electric car modules are very good, a scooter might be able to handle them.They are designed for safety, this takes additional space and weight that may be too much for an ebike, but a scooter has more room and weight capacity.
The requirements for this battery aren't clear and they are not all in one place, they are spread throughout this thread. I would suggest you need to collect your requirements and budget in one posting, preferably the first in the thread, and be more specific about the max current.
Most RC or ebike batteries are not rated for unattended charging. People do it, but the manufacturer doesn't permit it. Most chargers are not rated for unattended charging either.
OK here goes.
48v minimum, up to 54v preferred.
Safety is important the bike will charge overnight unattended.
Hope to not have remove the battery from the bike to charge.
Minimum 10 miles per charge at 20-23 mph, 20 miles at 25 mph preferred (little to no pedal assist)
I don't have tools and equipment to build my own so that cost will need to be considered if building versus buying a ready pack.
$500-$700 price range.
