how much room do you have? I would either go with 4x 18ah batteries if room is not an issue and you want a long ride time, or 4x 14ah (same size as 12ah and 4 for 99$ shipped on ebay) If room and weight is an issue then 2x 10ah 6S lipo's run in series for 50v.

Would running 4- 25 ah battery cause any advantage or disadvantages?

advantage: range and slightly higher amp-ability
disadvantage: weight

other than that... not really, no

If you went with a better controller in the future capable of higher amp output the 25ah batteries would be better. Price per /aH the 18ah batts are hard to beat.

Please forgive me asking this as I’ve read several posts and stickies. What do you gain by increasing volts. From what I’ve read, a lower voltage motor can produce the same performance as higher volts.

That's probably somewhat true but you're looking at a specific motor rated at 48v for 1000w. If you had a motor rated for 2000w at 24v and you run it with 24, it's probably going to outperform your 48v setup (depending on weight, motor design, controller, maybe other factors.)

Someone who knows more about this may chime in but really it's a question of apples and oranges.

There is a point of diminished retruns on increased voltage, I believe primarily because of increased heat and insufficiently designed components.

It eventually boils down to watts, volts, amps, and maths.
