I have a 48 volt system on my motorcycle conversion. Four 12 volt 55 AH 22NF-AGM Lead Acid UB12550 Batteries in series. An Alltrax AXE4834 300 AMP controller. A MARS ME0709 18 HP / 300 AMP peak motor (8 HP / 125 AMP continuous).
My current (no pun intended) top speed is 45 MPH.
To go faster I plan on adding 2 more batteries which will give me a 72 volt system. Of course I will have to upgrade my controller to either the AXE7234 200 AMP or the AXE7245 450 AMP.
To increase the range I need to up the AH, and that's where I am confused. I know in the parallel configuration the Amp Hours are added up, but where do the extra Amp Hours go when I add the additional two batteries like I am planning to do? I realize I will be carrying the additional weight.
If I limit myself to 45 MPH top speed Is my range going to increase at all?
