I just bought a Schwinn s500 electric scooter.
24V 500W motor, two 12V 10A lead-acid connected in serial.
I'm worried about the lead-acid battery, read that it shouldn't be discharged too deep. I'm thinking of replacing the battery to a NiMH type so that I can use almost all capacity every time.
Can I use 20 of D size cells (10000 mAh) all connected in serial, to make a 24V 10A battery pack?
I read some equations like 500watt/24V = 21A, so that I would need a power system that can supply 21A continous current. Does this sound right? If so, does that mean the D cells can only produce a current of 10A, so I'd only be able to use half of the 500 watt motor power?
How about using 20 of Ni-Cad?
Thanks in advance,
