Hello all,
My first post here, nice to see that there is a huge community interested in EVs
My question:
- I intent to mount my own bike that will run at 45Km/h (maximum speed by law) and make ~60Km distance (if more, better, of course...)
- I have 4 (lead-acid) batteries, each one with 12V 20A, their connection outputs 48V 20A (I can´t escape from this, since I already have them from my brother "old" crashed bike, and that is all that is left for me)
So, I´m interest in one of these motors (in my case they must be BLDC motors only - to fit right in the middle of the bike frame - "mid-drive" motor)
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
So with the above batteries output specifications, what could went wrong with these motors, merely as examples?...
Motor N.1) 350W (36V/48V) 12.5A ...
Motor N.2) 1200W (48V) 32A ...
1 - Nothing, all depends from the controller?... (The amps and watts from the controller must have an exact match with the motor ones?)
2 - In the 350W the motor (with only 12.5A) will be overpowered and could be fried?...
3 - In the 1200W the motor (with 32A) will be underpowered... but it will run?...
4 - I really have to find and exact macth for my 24V 20AH batteries?...
Thanks in advance for all suggestions/tips/ideas!
