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!
 
Welcome to the forum. We usually only see Heinsmann hub motors on the Iacocca e-bikes. I almost bought one a few years back.
Most people like the Ping LiPo batteries packs, but they are pricey.
Plenty of LiPo pack choices on ebay like bottle batteries, frog packs, etc.
