My battery pack needs to be replaced and I'm looking into lithium. The new pack is 144 volts using CALB CA180BFI. The new pack will be 45 cells 34 in the engine battery box and 11 in the gas tank box. this will free up the front trunk battery box so I can carry a spare tire again. I'll be mounting the charger, relays and 12v battery on the wall between the gas tank/front trunk.
The current battery pack weighs 1152 lbs. and the new will be 562 lbs. saving almost 600 lbs.
The down side is the price about $13,000.00 and the people selling the batteries have the same ethic as Electro, no phone/email replies.
