I have an Electric Wheel 400 bike (EW-400) http://high5scooters.com/productinfo/ew400.htm. I am upgrading my electric bike and I removed the stock controller and connected my stock 36v lithium battery in series to another 51.8v lithium battery http://www.batteryspace.com/highpowerpolymerli-ionbattery518v10ah518wh40adrainrate.aspx with Lyen’s 18 FET 4115 MOSFET 84-132V Real Highway Speed Controller. In addition, I bought 100v diodes to place in series of the batteries. I also connected headlights, taillights, & horn running through a 12v converter in the series as well. In addition, have a Cycle Analyst running with the set up that reads 99v is in the series. I connected everything and it ran for about 30 ft and the power cut off. I sent back my aftermarket controller to Lyen and got it fixed. I’m afraid that I don’t have something connected correctly in series. I don’t want to connect the controller and have the same problem of not working again. I’m afraid the controller might burn out again since I didn’t change anything on my bike battery series. Would you please assist me in my electric bicycle battery and controller setup? Do I plug it in and hope it works and nothing else goes wrong? Please HELP!
