Double your range with a new Sur-Ron battery and tripple up your Power, torque and acceleration with the ASI BAC4000 OR ASI BAC8000 Controller.
Now you can go twice the distance and race at speeds up to 80MPH.
Unlike Sur-Ron upgrades from competitors - this battery is laser-welded and assembled by hand using only authentic SAMSUNG cylinder lithium cells and pure nickel plates. No pouch cell technology is involved here. The powder-coated stainless steel case is waterproof and crash-proof, even in extreme outdoor conditions.
This is completely Plug & Play bundle for the Sur-Ron power upgrade!
Order a kit, install it at home or at ourworkshop - schedule a remote programming session with one of our engineers to get a fine custom tune - and you ready to rip the trails with the 3-4x more power in comparision with stock Sur Ron.
