So here is the system: 4 12v 10Ah sla batteries in series to create a 48v battery powering 1000w motor on demand. I want to put another motor in that has a friction wheel that can be engaged on demand to recharge the 48v battery when engaged.
Q1: will short (3sec-30sec) periods when the second recharge motor is engaged harm the 48v battery system?
Q2: is a 48v dc motor the correct choice for the recharge motor?
Q: Does charging the batteries as a 48v (paired from 1st use) unit harm them?
Q3: if you were building this system, and you wanted the recharge motor, when engaged, to SLOW the system at the same approximate speed that brakes on a bicycle(traveling up to 30 mph on 26" wheels) would, what wattage would you recommend? Given that the wheel that makes contact is 2-3' in diameter.
