I Just joined! I have a Specialized "Stumpjumper" with a Heinsmann 400w rear hub motor, a Yiyun Tech yk31c controller and 3 12v 7Ah SLA batteries. The batteries have died over the winter and I am looking to replace them. I am looking for suggestions for a battery pack that is lighter and more compact. All and any ideas are appreciated.
Cheers!
