Bac 4000 controller and 72v battery question?

[Derek91]

Does the 72v battery from litespeedbikes.com give you that much more speed and power than just having the bac4000 controller with the stock battery. If so how much more. I ordered just the controller for one of my Sur Ron’s and I’m debating On getting the battery but $1500 and giving up my stock battery for 3 weeks is allot.

Definitely dont give up you 60v battery if you do this. Pay the extra money for the 72v drop in and sell the 60v or keep it as backup. It will still work.
