Is there an option of replacing the flooded lead acid batteries for LiFePO4?
I'm certain its doable. I've converted 3 golf carts from Lead Acid to LiFePO4, and its been quite easy. From 2 minutes of googling, it appears that Polaris utilizes 8 standard 12V batteries in a 48V setup. Would be quite easy to convert. Depending on the desired range and performance, you could convert for $2500 on up to $15,000 if you got really crazy with it. To match the standard 15kWh Polaris's oem lead acid setup uses will run about $6500, but remember the lead acid replacement is already over $3,000 thus its just a $3500 delta with upside in both discharge performance and batttery lifespan of 3X.
One potentially major downside to the conversion in a SxS setup is that this will relocate the center of gravity on the vehicle. It could possibly ride rougher as well. I have a Yamaha DRIVE2 ADVENTURER SPORT 2+2 which is their upgraded golf cart modified to be more in the SxS space and it needs softer shocks to smooth out the ride after 200+ pounds of weight loss.
