I'm new to ebike building. My bike has a 48v 500w rear hub motor and integrated 500Wh 48V/10.4Ah in frame battery. Max controller current is 22 A. I don't know what type of dual battery balancer I need. I'm planning to get a 48v 30 ah battery with max 40 A dual battery balancer. Will it burn my bike? I posted a link to my bike' controller and balancers from internet.
