Battery upgrade

[springer03]

So after a ride last week with my wife we made it 39 miles with the stock rad battery, making it back just short of our car before the batteries cut off.
I've decided to upgrade our batteries on our bikes to get greater range. We will be getting 4 batteries, 2 each, so we both can bring a spare. I've been looking at the 52v batteries to get the most range.

We have already upgraded to the Bolton controller and Bafang 750 motor. (Radrover 5 and Radrunner Plus)

I'm looking at the Fat shark 52v 17.5ah batteries and noticed different Bms(30 and 40)and different max burst/max discharge amps(50,60 and 85a)
I don't really care about more power/speed so much(although it wouldn't hurt ), as most of our riding is on a mostly level rail trail using pedal assist 2 and the controller and motor upgrade has made any of the steep hills around my neighborhood no problem.
Would any of these outputs make much of a difference in range using only pedal assist? (with limited throttle use)
Would the 85a max burst be to much for a 35a controller?

Thanks!

the battery with the highest max burst rate will likely have a slight speed and range advantage.

the max burst rating of a battery is the max power the battery can provide for short periods. the max draw of the 35a controller is 35a. as long as the max burst rating of the battery is well over 35a there should be no issues.

Just wanted to be sure before I ordered.
