I live in a very rural area so I built with range in mind. That is why I decided to go with lithium. I don't think I could have gotten the range I needed with lead acid. As we all know lithium is more expensive and somewhat more complex but I am glad I spent the extra money to go that route. My only regret is that I scrimped on the doner as I had to spend alot of time and money to get her into shape.
Charger:
Cheap Yang Ming on board charger, BCO 6006BL balancing charger
Conversion time and cost:
About six to eight months. Ispent alot of time fixing up doner and waiting for batteries. Cost was about $6,000.00.
Curb weight:
Not sure but I believe it is lighter than stock.
Drivetrain:
Direct chain drive, 14t drive 60t driven
Lighting:
Explained in method for 12v system:
Method for 12v system:
For now I use stock battery for lights. Headlight and running lights are not hooked up yet. Contactor is run on stock 12v battery.
Typical range:
Effective range of about 50 miles. I road 60 miles but just barely made it home. My average ride is about 35 miles at 45 to 50 mph and I use about 20 amp hours per ride.
